I am trying to run theWS2812 LED Stripdriver on an STM32L431 using the SPI mode. The SPI is used asTransmit Only, and only theMOSIpin is connected and defined in the DTS. When the LED driver is writing to the LED's the SPI driver gets stuck in an infinite loop waiting for theRXN...

The SPI HAL drivercanbe usedasfollows: (#) **Declare a SPI_HandleTypeDef handle structure**, for example:`SPI_HandleTypeDef hspi`; (#)**Initialize the SPIlow level resources** by implementing the `HAL_SPI_MspInit()` API:(##) **Enable the SPIx interface clock**(##) **SPI pins conf...
stm32_spi_eeprom_interrupt You can use theopen_systemcommand to open the Simulink® models. For example, use this command for a STM32 Processor based hardware board: open_system('stm32_spi_eeprom_interrupt.slx'); Read and Write Data to SPI EEPROM Using the SPI Transmit Block, the SPI ...

I have only the one Nucleo, so I compiled the project SPI_FullDuplex_ComDMA set as master. This example is intended to transmit a message from one board as a master to another board as a slave. Since I don't have another board, I simply scoped the SCK pin and I see nothing when ...
