UART) can significantly boost performance while reducing workload on the MCU (microcontroller) core , therefore configuring the DMA controller in circular mode can be straightforward for peripherals. h files per peripheral' on the Code Generator Tab. After 1 successful data transmission, the state flag remains on BUSY. Normal mode: In this mode, DMA starts transferring data and when it transfers all elements, it stops. Maybe it is something STM32 specific that needs more special handling in a UART's driver implementation. Higher baudrate means lower frame time for single byte. 2 Installing the files To install the shell into an existing project, simply copy the source files into your project. Unlike SPI which is a communication protocol, the UART is a physical circuit inside the STM32 The UART errors aren't hundled when using blocking transfer mode and it is recommanded to use non blocking mode to avoid such kind of issues. c and shell. I have tested it on Macos, so there might be some issue if you are using different OS. Since I gave both uart 2 and uart 3 the same interrupt priority, I am stalling my receive interrupt handler which ultimately results in my missing bytes. I guess they are noise, frame and noise+frame(?) errors, and after this error the UART Currently HAL_USART Handler doesn't handle the case where RXNEIE=1, RXNE=0, ORE=1 and the USART ISR goes off constantly.
