ESP32 -通过UART通信时出现任务错误 ESP32是一款基于Tensilica Xtensa LX6微处理器的低功耗、高性能的Wi-Fi和蓝牙双模模组。它广泛应用于物联网、智能家居、工业自动化等领域。 在通过UART通信时出现任务错误可能是由于以下原因导致的: 配置错误:请确保UART通信的引脚配置正确,并且波特率等参数设置与对端设备一致。

However, I found that if I call `usb_serial_jtag_ll_txfifo_flush` (from `hal/usb_serial_jtag_ll.h`) it also works. But thanks for checking anyway! 3 posts • Page1of1 Return to “ESP-IDF” Jump to Who is online Users browsing this forum:Baidu [Spider],ChatGPT-Userand 2 guests...
串口驱动的核心文件为:bsp_uart_fifo.c, bsp_uart_fifo.h。 这里面包括有串口硬件的配置函数、中断处理函数,以及串口的读写接口函数。还有ptinft函数的实现。 每个串口都有2个FIFO缓冲区,一个是用于发送数据的TX_FIFO,一个用于保存接收数据的RX_FIFO。 我们来看下这个FIFO的定义,在bsp_uart_fifo.h文件。 AI检...
