Audio

The STM32303C-EVAL evaluation board supports stereo audio play and microphone
recording by an external headset connected on audio jack CN11. An audio DAC CS42L52 is
connected to the I2S port of the STM32F303VCT6 microcontroller. The microphone on
headset or microphone which is reserved on board (U26, default unmounted) are connected
to ADC of CS42L52. The CS42L52 can be configured via I2C2 and be driven by either
I2S_MCK at PA9 or the external I2S clock mode supported by an external PLL (U12).
Note: Please keep VDD to 3.3 V (Power mode 1 in
The I2C communication depends on JP5 and JP6 jumper setting.

The I2C address of CS42L52 is 0b1001010, and that of External PLL CS2200 is
0b1001110.
Boot0-related jumper
Bootloader_BOOT0 is managed by pin 6 of connector CN8 (RS232 DSR
signal) when JP9 is closed. This configuration is only used for the boot
JP9
loader application.
