Why Are 2 Data Points Lost During SPI Transmission?

Why Are 2 Data Points Lost During SPI Transmission?

Someone used the STM32F4 chip to validate the SPI functionality. When using two on-chip SPI modules for transmission and reception based on interrupts, it was found that there was always a loss of received data, seemingly losing the last 2 data points. The code used the HAL library’s API functions. What could be the reason? … Read more
