Original question:
CC2650STK: CC2650launchpad
能写一份有关cc2650launpad uart接受和发送的程序吗？我在uart例程上改了好久，说是IDO-3，ID0-2系统默认打不开
例程中已经有了UART_read和UART_write的示例
串口引脚的定义在CC2650_LAUNCHXL.h中：
/* UART Board */#define Board_UART_RX IOID_2 /* RXD */#define Board_UART_TX IOID_3 /* TXD */#define Board_UART_CTS IOID_19 /* CTS */#define Board_UART_RTS IOID_18 /* RTS */
调了挺久的呢，能不能帮忙给一份打开串口IDO3，2的例程，rx接受不到数据，usb转ttl串口助手也搜不到数据，能给一份打开串口接受数据，串口调试助手接收数据的例程嘛，非常感谢呢。
对于特定的应用，需要自己修改代码，参考下面的说明文档：
