C Designated Initializer

[[Category:C]][[Category:Work in progress]]{{metadesc|C Designated Initializer C99 feature}}
[[C Designated Initializer]]s is a feature which was introduced in the C99 standard.

== The problem ==

It is quite common in C programs, to include an array of strings:

<syntaxhighlight lang="C">
// Strings for debug
char *str[] = {
"Program start",
"Some stuff happened",
"Some other stuff happened",
"Disastrous error",
"Program end"
};
</syntaxhighlight>

These strings can now be used throughout the program by referencing the array element.

<syntaxhighlight lang="C">
printf("%s\n", str[0]);
</syntaxhighlight>

With only a few strings, this '''can''' be managed, but it is quite obvious that as the list grow longer, it will become unmanageable, and also statements like: "printf("%s\n", str[0]);" are not very readable.

To make the code more readable, it is common to include an enum or defines to refer to the array element.

<syntaxhighlight lang="C">
typedef enum {
STR_START = 0,
STR_STUFF = 1,
STR_OTHER = 2,
STR_DISASTER = 3,
STR_END = 4
} str_idx_t;

// Strings for debug
char *str[] = {
"Program start",
"Some stuff happened",
"Some other stuff happened",
"Disastrous error",
"Program end"
};
</syntaxhighlight>

The strings can now be referred like:

<syntaxhighlight lang="C">
printf("%s\n", str[STR_START]);
</syntaxhighlight>

Which is obviously much more readable.

Synchronization between the enum and the array is still the responsibility of the programmer, and as the list grow long, errors can and will creep in.

== The solution: Designated Initializer ==

The solution to the synchronization problem, was introduced in C99 as [[Designated Initializers]]. With those, the above piece of code can be rewritten as:

<syntaxhighlight lang="C">
typedef enum {
STR_START = 0,
STR_STUFF = 1,
STR_OTHER = 2,
STR_DISASTER = 3,
STR_END = 4
} str_idx_t;

// Strings for debug
char *str[] = {
[STR_START] = "Program start",
[STR_STUFF] = "Some stuff happened",
[STR_OTHER] = "Some other stuff happened",
[STR_DISASTER] = "Disastrous error",
[STR_END] = "Program end"
};
</syntaxhighlight>

The order of the strings in the array as written is no longer relevant as they will be sorted following the enum. Also if there are "holes" (undefined strings" it will result in a NULL string in the array,

After spending some time with first various AtMega 8 bit processors and then Espressif's ESP32 I decided to explore STMicroelectronics [[STM32]] series of micro processors. Initially that seems a daunting experience. There are literally hundreds of different [[STM32]] [[MCU]]s and understanding the differences is important in picking the right one for any given project.

According to Gemini, at the time of writing this, 1631 distinct STM32 microcontroller (MCU) model numbers listed in STMicroelectronics' active portfolio.

<div class="res-img">

In this article we will describe the naming conventions of [[STM32]] [[MCU]]s and help you understand what model to pick.

STM32 processors are grouped in a number of families. The following chart give a brief overview of these and the naming conventions:

Like most [[Streamline]] blades, this board got a number of solder jumpers which can be used to modify the default behavior:

<div class="res-img">
[[File:Sl io audio dac top render.png|1000px]]

By default, the blade will be connected to I2S2. This can be changed by removing the zero ohm resistors: R2, R3 and R4 and then selecting the appropriate I2S port using the 3, 3-way solder jumpers.

R1, R6, R6 and R7 are strap pins that select the default behavior of the PCM5102a. Remove these and use solder jumpers to select new default behavior.

Notes;

†† The STM32C071 has only one half-duplex I2S, and the _SD pin can either be in INPUT or OUTPUT mode. Many pins, how do we map?

††† I2S3_WS is ONLY mapped on PA15 (used for SWDIO), except on STM32C551 which ALSO has it on PB8.

Streamline Peripheral Pin Mapping

2026-09-10T06:10:18Z

Lth: /* SPI */

[[Category:Streamline]][[Category:Work in progress]]

== General notes ==
field means that all MCUs can be mapped identically.

field means it is missing the peripheral.

field means that pins are not same across all MCUs.

field is I2Sx_MCK only exist on one pin.

=== RP2350 ===

Trying to avoid 12 - 19 as these can be used for HSTX but they should be wired to backplane.

== SWD ==

Notes;

†† The STM32C071 has only one half-duplex I2S, and the _SD pin can either be in INPUT or OUTPUT mode. Many pins, how do we map?

††† I2S3_WS is ONLY mapped on PA15 (used for SWDIO), except on STM32C551 which ALSO has it on PB8.

Streamline Peripheral Pin Mapping

2026-09-10T06:06:21Z

Lth: /* SPI */

[[Category:Streamline]][[Category:Work in progress]]

== General notes ==
field means that all MCUs can be mapped identically.

field means it is missing the peripheral.

field means that pins are not same across all MCUs.

field is I2Sx_MCK only exist on one pin.

=== RP2350 ===

Trying to avoid 12 - 19 as these can be used for HSTX but they should be wired to backplane.

== SWD ==

Notes;

†† The STM32C071 has only one half-duplex I2S, and the _SD pin can either be in INPUT or OUTPUT mode. Many pins, how do we map?

††† I2S3_WS is ONLY mapped on PA15 (used for SWDIO), except on STM32C551 which ALSO has it on PB8.

Streamline Peripheral Pin Mapping

2026-09-10T05:36:20Z

Lth: /* SPI */

[[Category:Streamline]][[Category:Work in progress]]

== General notes ==
field means that all MCUs can be mapped identically.

field means it is missing the peripheral.

field means that pins are not same across all MCUs.

field is I2Sx_MCK only exist on one pin.

=== RP2350 ===

Trying to avoid 12 - 19 as these can be used for HSTX but they should be wired to backplane.

== SWD ==

Notes;

†† The STM32C071 has only one half-duplex I2S, and the _SD pin can either be in INPUT or OUTPUT mode. Many pins, how do we map?

††† I2S3_WS is ONLY mapped on PA15 (used for SWDIO), except on STM32C551 which ALSO has it on PB8.

Streamline Peripheral Pin Mapping

2026-09-10T05:32:52Z

Lth: /* I2C */

[[Category:Streamline]][[Category:Work in progress]]

== General notes ==
field means that all MCUs can be mapped identically.

field means it is missing the peripheral.

field means that pins are not same across all MCUs.

field is I2Sx_MCK only exist on one pin.

=== RP2350 ===

Trying to avoid 12 - 19 as these can be used for HSTX but they should be wired to backplane.

== SWD ==

Notes;

†† The STM32C071 has only one half-duplex I2S, and the _SD pin can either be in INPUT or OUTPUT mode. Many pins, how do we map?

††† I2S3_WS is ONLY mapped on PA15 (used for SWDIO), except on STM32C551 which ALSO has it on PB8.

Streamline Peripheral Pin Mapping

2026-09-10T05:31:46Z

Lth: /* I2C */

[[Category:Streamline]][[Category:Work in progress]]

== General notes ==
field means that all MCUs can be mapped identically.

field means it is missing the peripheral.

field means that pins are not same across all MCUs.

field is I2Sx_MCK only exist on one pin.

=== RP2350 ===

Trying to avoid 12 - 19 as these can be used for HSTX but they should be wired to backplane.

== SWD ==

Notes;

†† The STM32C071 has only one half-duplex I2S, and the _SD pin can either be in INPUT or OUTPUT mode. Many pins, how do we map?

††† I2S3_WS is ONLY mapped on PA15 (used for SWDIO), except on STM32C551 which ALSO has it on PB8.

Streamline Peripheral Pin Mapping

2026-09-10T05:30:04Z

Lth: /* UARTs */

[[Category:Streamline]][[Category:Work in progress]]

== General notes ==
field means that all MCUs can be mapped identically.

field means it is missing the peripheral.

field means that pins are not same across all MCUs.

field is I2Sx_MCK only exist on one pin.

=== RP2350 ===

Trying to avoid 12 - 19 as these can be used for HSTX but they should be wired to backplane.

== SWD ==

Notes;

†† The STM32C071 has only one half-duplex I2S, and the _SD pin can either be in INPUT or OUTPUT mode. Many pins, how do we map?

††† I2S3_WS is ONLY mapped on PA15 (used for SWDIO), except on STM32C551 which ALSO has it on PB8.

Streamline Peripheral Pin Mapping

2026-09-10T05:29:41Z

Lth: /* UARTs */

[[Category:Streamline]][[Category:Work in progress]]

== General notes ==
field means that all MCUs can be mapped identically.

field means it is missing the peripheral.

field means that pins are not same across all MCUs.

field is I2Sx_MCK only exist on one pin.

=== RP2350 ===

Trying to avoid 12 - 19 as these can be used for HSTX but they should be wired to backplane.

== SWD ==

Notes;

†† The STM32C071 has only one half-duplex I2S, and the _SD pin can either be in INPUT or OUTPUT mode. Many pins, how do we map?

††† I2S3_WS is ONLY mapped on PA15 (used for SWDIO), except on STM32C551 which ALSO has it on PB8.

Streamline Peripheral Pin Mapping

2026-09-10T05:29:05Z

Lth: /* UARTs */

[[Category:Streamline]][[Category:Work in progress]]

== General notes ==
field means that all MCUs can be mapped identically.

field means it is missing the peripheral.

field means that pins are not same across all MCUs.

field is I2Sx_MCK only exist on one pin.

=== RP2350 ===

Trying to avoid 12 - 19 as these can be used for HSTX but they should be wired to backplane.

== SWD ==

Notes;

†† The STM32C071 has only one half-duplex I2S, and the _SD pin can either be in INPUT or OUTPUT mode. Many pins, how do we map?

††† I2S3_WS is ONLY mapped on PA15 (used for SWDIO), except on STM32C551 which ALSO has it on PB8.

Streamline Peripheral Pin Mapping

2026-09-10T04:45:59Z

Lth: /* I2C */

[[Category:Streamline]][[Category:Work in progress]]

== General notes ==
field means that all MCUs can be mapped identically.

field means it is missing the peripheral.

field means that pins are not same across all MCUs.

field is I2Sx_MCK only exist on one pin.

=== RP2350 ===

Trying to avoid 12 - 19 as these can be used for HSTX but they should be wired to backplane.

== SWD ==

Notes;

†† The STM32C071 has only one half-duplex I2S, and the _SD pin can either be in INPUT or OUTPUT mode. Many pins, how do we map?

††† I2S3_WS is ONLY mapped on PA15 (used for SWDIO), except on STM32C551 which ALSO has it on PB8.

Streamline Peripheral Pin Mapping

2026-09-10T04:44:29Z

Lth: /* I2C */

[[Category:Streamline]][[Category:Work in progress]]

== General notes ==
field means that all MCUs can be mapped identically.

field means it is missing the peripheral.

field means that pins are not same across all MCUs.

field is I2Sx_MCK only exist on one pin.

=== RP2350 ===

Trying to avoid 12 - 19 as these can be used for HSTX but they should be wired to backplane.

== SWD ==

Notes;

†† The STM32C071 has only one half-duplex I2S, and the _SD pin can either be in INPUT or OUTPUT mode. Many pins, how do we map?

††† I2S3_WS is ONLY mapped on PA15 (used for SWDIO), except on STM32C551 which ALSO has it on PB8.

Streamline Peripheral Pin Mapping

2026-09-10T03:24:11Z

Lth: /* I2C */

[[Category:Streamline]][[Category:Work in progress]]

== General notes ==
field means that all MCUs can be mapped identically.

field means it is missing the peripheral.

field means that pins are not same across all MCUs.

field is I2Sx_MCK only exist on one pin.

=== RP2350 ===

Trying to avoid 12 - 19 as these can be used for HSTX but they should be wired to backplane.

== SWD ==

Notes;

†† The STM32C071 has only one half-duplex I2S, and the _SD pin can either be in INPUT or OUTPUT mode. Many pins, how do we map?

††† I2S3_WS is ONLY mapped on PA15 (used for SWDIO), except on STM32C551 which ALSO has it on PB8.

Streamline Peripheral Pin Mapping

2026-09-10T03:11:59Z

Lth: /* UARTs */

[[Category:Streamline]][[Category:Work in progress]]

== General notes ==
field means that all MCUs can be mapped identically.

field means it is missing the peripheral.

field means that pins are not same across all MCUs.

field is I2Sx_MCK only exist on one pin.

=== RP2350 ===

Trying to avoid 12 - 19 as these can be used for HSTX but they should be wired to backplane.

== SWD ==

Notes;

†† The STM32C071 has only one half-duplex I2S, and the _SD pin can either be in INPUT or OUTPUT mode. Many pins, how do we map?

††† I2S3_WS is ONLY mapped on PA15 (used for SWDIO), except on STM32C551 which ALSO has it on PB8.

== ADCs ==
ADCs are so numerous that comparative tables are difficult to establish.

Streamline Peripheral Pin Mapping

2026-09-10T03:11:20Z

Lth: /* UARTs */

[[Category:Streamline]][[Category:Work in progress]]

== General notes ==
field means that all MCUs can be mapped identically.

field means it is missing the peripheral.

field means that pins are not same across all MCUs.

field is I2Sx_MCK only exist on one pin.

=== RP2350 ===

Trying to avoid 12 - 19 as these can be used for HSTX but they should be wired to backplane.

== SWD ==

Notes;

†† The STM32C071 has only one half-duplex I2S, and the _SD pin can either be in INPUT or OUTPUT mode. Many pins, how do we map?

††† I2S3_WS is ONLY mapped on PA15 (used for SWDIO), except on STM32C551 which ALSO has it on PB8.

Streamline Peripheral Pin Mapping

2026-09-10T03:09:53Z

Lth: /* UARTs */

[[Category:Streamline]][[Category:Work in progress]]

== General notes ==
field means that all MCUs can be mapped identically.

field means it is missing the peripheral.

field means that pins are not same across all MCUs.

field is I2Sx_MCK only exist on one pin.

=== RP2350 ===

Trying to avoid 12 - 19 as these can be used for HSTX but they should be wired to backplane.

== SWD ==

Notes;

†† The STM32C071 has only one half-duplex I2S, and the _SD pin can either be in INPUT or OUTPUT mode. Many pins, how do we map?

††† I2S3_WS is ONLY mapped on PA15 (used for SWDIO), except on STM32C551 which ALSO has it on PB8.

Streamline Peripheral Pin Mapping

2026-09-10T03:09:30Z

Lth: /* UARTs */

[[Category:Streamline]][[Category:Work in progress]]

== General notes ==
field means that all MCUs can be mapped identically.

field means it is missing the peripheral.

field means that pins are not same across all MCUs.

field is I2Sx_MCK only exist on one pin.

=== RP2350 ===

Trying to avoid 12 - 19 as these can be used for HSTX but they should be wired to backplane.

== SWD ==

Notes;

†† The STM32C071 has only one half-duplex I2S, and the _SD pin can either be in INPUT or OUTPUT mode. Many pins, how do we map?

††† I2S3_WS is ONLY mapped on PA15 (used for SWDIO), except on STM32C551 which ALSO has it on PB8.

Streamline Peripheral Pin Mapping

2026-09-10T02:08:59Z

Lth: /* UARTs */

[[Category:Streamline]][[Category:Work in progress]]

== General notes ==
field means that all MCUs can be mapped identically.

field means it is missing the peripheral.

field means that pins are not same across all MCUs.

field is I2Sx_MCK only exist on one pin.

=== RP2350 ===

Trying to avoid 12 - 19 as these can be used for HSTX but they should be wired to backplane.

== SWD ==

Notes;

†† The STM32C071 has only one half-duplex I2S, and the _SD pin can either be in INPUT or OUTPUT mode. Many pins, how do we map?

††† I2S3_WS is ONLY mapped on PA15 (used for SWDIO), except on STM32C551 which ALSO has it on PB8.

Streamline Peripheral Pin Mapping

2026-09-10T02:07:25Z

Lth: /* UARTs */

[[Category:Streamline]][[Category:Work in progress]]

== General notes ==
field means that all MCUs can be mapped identically.

field means it is missing the peripheral.

field means that pins are not same across all MCUs.

field is I2Sx_MCK only exist on one pin.

=== RP2350 ===

Trying to avoid 12 - 19 as these can be used for HSTX but they should be wired to backplane.

== SWD ==

Notes;

†† The STM32C071 has only one half-duplex I2S, and the _SD pin can either be in INPUT or OUTPUT mode. Many pins, how do we map?

††† I2S3_WS is ONLY mapped on PA15 (used for SWDIO), except on STM32C551 which ALSO has it on PB8.
