How can I enable i2s support

[lihuate]

I want to connect (i2s), but I won't configure it. Please tell me how mpconfigboard should be configured 😂(‾◡◝)。,

I2S is supported out of the box on a Pyboard. Just ensure you have recent firmware. On a Pyboard 1.1:

>>> import machine
>>> dir(machine)
['__class__', '__name__', '__dict__', 'RTC', 'ADC', 'DEEPSLEEP_RESET', 'HARD_RESET', 'I2C', 'I2S', 'PWRON_RESET', 'Pin', 'SOFT_RESET', 'SPI', 'Signal', 'SoftI2C', 'SoftSPI', 'Timer', 'UART', 'WDT', 'WDT_RESET', 'bitstream', 'bootloader', 'deepsleep', 'disable_irq', 'enable_irq', 'freq', 'idle', 'info', 'lightsleep', 'mem16', 'mem32', 'mem8', 'reset', 'reset_cause', 'rng', 'sleep', 'soft_reset', 'time_pulse_us', 'unique_id']

No i2s ！ My Pyboard version 1.19 ＞﹏＜

I have installed the latest daily build and it is present:

MicroPython v1.19.1-782-g699477d12 on 2022-12-20; PYBv1.1 with STM32F405RG
Type "help()" for more information.

I also built from sources downloaded today, and it is present.

The poster uses a different board.

I think you should simply add something like this in your f429 mpconfigboard.h:

// I2S buses
#define MICROPY_HW_I2S1      (1)
#define MICROPY_HW_I2S2      (1)
#define MICROPY_HW_I2S3      (1)

Thank you all. This device is working properly. [](￣▽￣)* o(￣▽￣)ブ o(￣▽￣)o。

• Issue Status：solved
• mcu：STM32F429ZG
• edition：MicroPython v1.19.1-782-g699477d12

 //Write a mpconfigboard.h in
// I2S buses
#define MICROPY_HW_I2S2      (1)
#define MICROPY_HW_I2S3      (1)

result：

MicroPython v1.19.1-782-g699477d12-dirty on 2022-12-24; newPi with STM32F429
