libopencm3: GPIO pin configuration
WebI want to use the SPI as a full-duplex master (sending and receiving data simultaneously). I have read many posts about the NSS deficiencies in the STM32 implementation and I believe that although NSS may be asserted low automatically, it must be cleared high by interrupting on (SPI RX flag ?). If someone has the detail of how to configure the ...

WebApr 24, 2024 · 0. If each entry in the array can point to different port, the simplest way is to initialize the pins in a for loop one at a time. Take a port and pin, init it. Take next port and pin, init it. There are faster ways too, but since the IO ports are each dynamically set in run-time by the user anyway, it makes little difference how it is done. WebApr 26, 2024 · 1. I got a STM32 Nucleo-F410RB development board and was able to get my external DAC working with SPI1, both with busy-wait and with DMA. I then designed my own custom PCB, built it and was able to flash it. During the design phase I switched from using SPI1 to SPI5 because I needed the SPI1 pins for other functions.
