SPI bus communication

SPI signals are connected to the MEMS connector, Wi-Fi module and PLM. Use carefully
the signal enable of the listed devices to select only one at a time. SPI signals can be also
configured as analog inputs of the STM32 microcontroller ADC for optionally attached
analog MEMS module. Please refer to
