WARNING: Some Arduino IOs are shared with other functions:
Following ARD signals are multiplexed or shared with other functions. In case ARDUINO
UNO is connected, take care that the corresponding features are disconnected or well
configured :
ARD_D7 : DCMI_HSYNC/DE (Camera conflict)
ARD_A5 : STMOD+_PWM (STMod+ / PMOD conflict)
ARD_D15 : I2C3_SCL (shared with STMod+)
ARD_D14 : I2C3_SDA (shared with STMod+)
ARD_D13 : DSI_SPI2_SCK (SPI2_SCK shared with STMod+/PMOD and DSI option)
ARD_D12 : DSI_SPI_D/CX (SPI2_MISO shared with STMod+/PMOD and DSI option)
ARD_D11 : DSI_SPI2_MOSI (SPI2_MOSI shared with STMod+/PMOD and DSI option)
