GD32F427 serial port idle interrupt DMA transceiver

Recently, I used GD32F427 to switch from the original ST HAL library to the GD library. It took a while to adjust the serial port DMA transceiver of GD32F427. Let’s go directly to the code. The same set of codes has adjusted USART0, USART1, USART2, and USART5. This article takes USART0 as an example. First […]

STM32F103 USART1 IDLE FLAG

STM32F103 USART1 IDLE flag will be automatically cleared after entering the interrupt ISR Currently, when receiving Modbus Frame of variable length, it is still based on RXNE. I want to try using STM32 DMA + USART IDLE to see if I can reduce the number of interrupts/CPU usage. Data transmission frequency is low, length RX […]
