Central to sending and receiving data with a UART is the USART_SR (Status Register): The bits to look out for here are: 1. TXE(Transmit data register empty). 2. RXNE(Receive data register not empty). The first (TXE) is to be checked every time that we wish to send a byte: Vice versa, to read we need to … See more Which USART peripheral to use does seem like a pretty easy choice especially when the lower-end STM32F0 MCUs have only two USARTs. … See more As with the other peripherals, at boot the USART peripheral is unpowered. To change this, we must toggle a bit in the appropriate RCC … See more While there are a lot of positive things that could be said about the STM32F1 family of MCUs, their GPIO peripherals are not among these. The reason for this becomes once again apparent when looking at configuring AF mode … See more The general-purpose I/O (GPIO) peripherals do not have just one single function.

WebThis first sets AFIO_MAPR to 0x02000000 to disable the JTAG pins. Then, while remapping TIM4 it sets AFIO_MAPR to 0x04001000 which both remaps TIM4 and completely disables JTAG and SWD. This happens because the undefined read of the SWJ_CFG bits gets written back to the AFIO_MAPR. WebUnfortunately the related bits in AFIO->MAPR are write only. Reading these three bits is undefined. In fact, depending on the settings of AFIO->MAPR I observed that a 0x4 is …
