I am trying to use the HAL driver - HAL_I2C_MEM_READ(....)The stm32 is the master and there is a slave i2c device that I want to read from. The I2C transaction goes like this: <start> <dev address> <register that I want to read address> <start> <dev...

STM32fxx I2C mem read issue

Currently we make use of three SPI busses on a STM32F405. SPI1 is a slave and SPI 2/3 are masters. I switch SPI1 to master mode and it just doesn't work. I suspect the APB2 bus but I think I have it set correctly.
