I'm using a STM32G4 and communicating with multiple devices that use a 16 bit + 1 bit (write/read bit followed by six register address bits, 16 data bits, and a parity bit MSB first) on SPI. What I'm seeing is on transfers i have to shift my data 1 bit to the left for the devices to accept the write and reads vary but are mostly unusable. Is there a way to send non standard frame sizes, preferably with the clock and bits shifting continuously until the parity bit? I was hoping for a built in HAL or api method, but from my research it seems I may have to implement this completely in software, which i have not explored how to do just yet with this hardware.
