在app_uart.h中提供了两键的uart函数APP_UART_FIFO_INIT和APP_UART_INIT,一个是带 FIFO 缓冲的初始化串口函数,一个是不带 FIFO 缓冲的初始化函数,一般情况下使用带软件缓冲的 FIF0 的函数,减小数据溢出错误的发生几率。配置代码具体如下: //声明参数结构体 const app_uart_comm_params_t comm_params = { ...
* @details This function will receive a single character from the app_uart module and append it to * a string. The string will be be sent over BLE when the last character received was a * 'new line' '' (hex 0x0A) or if the string has reached the maximum data length. *@snippet [...

Enabled Interrupts 可以看到哪些硬件中断被打开了。 7. 连接设备# nrf-connect插件,底层调用的是nrfjprog或nrfutil命令来连接开发板上的JLink。因此,需要通过USB线连接到JLink口。 以nRF52840DK为例,中间最大的带有贴纸的芯片为JLink主控(官方称其为Interface MCU),左侧为JLink USB口,此接口可以用来给整块板供电。
