The STM32 USART_Irq example program shows how to configure and use the USART1 of STMicroelectronics STM32F103xx microcontroller in interrupt driven mode. The configuration of USART1 is 9600 Baud, 8 data bits, 1 stop bit, no parity and no flow control. Retargetting is used to read a ...
STM32-USART DMA_Interrupt例程的学习 这是固件库里的一个例程,决定从这里入手依次学习一下外设,下面是这个例程的介绍: This example provides a basic communication between USART1 and USART2 using DMA capability, flags and interrupts. First, the DMA transfers data from TxBuffer2 buffer to USART2 Transmi...

Both events can trigger an interrupt. Not all STM32 have IDLE LINE or RTO features available. When not available, examples concerning these features may not be used An example: To transmit1byte at115200bauds, it takes approximately (for easier estimation)~10us; for3 bytesit would be~30usin...
