Hi Nordic Team!
After developing our firmware on the nRF52 HDK, we designed our custom board, and we're starting to write our custom board configuration file.
The main problem I have is that there's no official documentation on how to do this.
From what I gathered around the forum, is that I need to define my custom board file assigning each pin it's function, and then change the board flag on the make file (see here).
On the other hand, there's also the possibility of editing the nrf_drv_config.h file (see here).
Finally, certain pins have to be configured trough their register if they want to be used for GPIO or other peripheral drivers (see here and here).
So my question is, do I have to do all three? Is writing the custom_board enough?
As a reference here's the mapping needed for our board design:
- GPIO Inputs: P0.00, P0.19, P0.20, P0.26, P0.29 and P0.30
- GPIO Outputs: P0.13, P0.17, P0.18, P0.21, P0.31
- Analog Inputs: AIN0, AIN1, AIN2, and AIN3
- TWI: P0.11(SCL) and P0.12 (SDA)
- UART: P0.28(TXD), P0.29(RXD), P.027(CTS) and P0.25(RTS)
- SPI: P0.14(MOSI), P0.15 (MISO) and P0.16 (SCK)
- PWM: P0.09
Our firmware is based on the nRF52832 using S132 SD and SDK ver 11.0 and we're using a GCC based environment.
Thanks in advance
