How to calc CRC16 for Modbus?

2021-06-01
My controller is STM32L462. I need to compute CRC16 for Modbus application. There is CRC initialization function:void MX_CRC_Init_CRC16(void) { hcrc.Instance = CRC; hcrc.Init.DefaultPolynomialUse = DEFAULT_POLYNOMIAL_DISABLE; hcrc.Init.DefaultI...

SPI CPHA affects NSS

2021-04-05
I use MCU STM32L462ET6TR. When I set CPHA=1, the NSS signal is always at low. When CPHA=0, NSS signal works normally. There is my initialization code:void MX_SPI1_Init(void) { hspi1.Instance = SPI1; hspi1.Init.Mode = SPI_MODE_MASTER; hspi1.Init...
