In order to be able to support selection of SPI or UART functions connection on PMOD by
software, a quad SPDT switch has been added on board. It is controlled by two GPIOs from
MFX_V3 circuit and enables MCU signal choice for pins 2, 3 and 4: refer to
Table 20
STMod+ chapter for switch description details (pin 1, 2, 3 and 4 of PMOD are common with
STMod+).
By default, STMod+ connector is selected, so STMOD+_SEL_0 and STMOD+_SEL_1
needs to be modified to support one of the PMOD interface configuration. Also, PMOD
shares GPIOs with other functions of the Board: for more detailed information please refer
to
Appendix A: GPIO assignment and sharing .
Note: Limitation: the PMOD interface is not compatible with JP7 setting at +1V8.
11.8 Camera module connector CN2
An 8-bit camera module function is supported thanks to the 30-pin dedicated ZIF connector
CN2. The reference of camera module to be used is STM32F4DIS-CAM. This module has
to be connected with caution before powering on the STM32L4R9I-DISCO Discovery board.
The camera module I²C addresses are 0x61 and 0x60. Camera can be used by default, but
one might take care about GPIO sharing and multiplexing with other function, in order to
program the good configuration. For more detailed information please refer to
Appendix A:
GPIO assignment and sharing .
Note: Limitation: the camera is not compatible with JP7 setting at +1V8.
