Re: uart baudrate and source clock by napster7c6 » Wed Jun 21, 2023 3:25 am If anyone is interested, I found a reason and problem was hardware. Esp32 (3.3V) connected to sim-module (1.8V) and level matching scheme (from sim-module datasheet) doesn't work with high baud rate...
hal库中uart的AutoBaudRateMode hal_uart_irqhandler,一、查询模式1.二、中断模式1.中断接收。1.1先看中断接收的流程(以USART2为例)在启动文件中找到中断向量USART2_IRQHandler找到USART2_IRQHandler的函数定义 可以看到这里又转到另一个函数里去了,再找下去:该函
Let's assume we are using the common UART configuration of 8N1 here too and have to use a baudrate of 115200. We can use the following formula: Bytes per second = baud rate / total bits per frame. So, at a baud rate of 115200 bps with an 8N1 configuration, we can send 11520 byte...
