As a Two MEMS microphone MP34DT01 mounted on STM32F4-Discovery is connected to the Inter-IC Sound (I2S) peripheral. Normally, this address will be given in the datasheet of the slave device PSoC6 MCU Inter-IC Sound (I2S) Example www. I want the STM32F4 act as master to generate the BCK and LRCK to raspberry pi which is act as slave (as shown image below) for clocking synchronize purpose. The STM32F4-DISCOVERY is a inexpensive demo board from ST Microelectronics. Although the entry-level STM32 microcontrollers (like the STM32F030) don’t support I2S, many intermediate versions do support it and you don’t necessarily need to a controller as advanced as the STM32F469. stm32f4 i2s example
