CC1310 rfPacketRX 加入UART功能问题

Hi,

我尝试在rfPacketRx例子中加入Uart输出信息, 通过在rxTask中插入按键中断处理来实现,  程序上电后正常接收数据包, 按键一次, 能正常

输出package 数目, 但是程序就不能返回或者挂掉, 需要reset才能接受数据, 程序内容如下:

rf发送函数是不会返回的，建议按键程序中先abort rf程序，下次需要接受再重启

你好，问题解决如下：

/*
* ======== buttonCallback ========
* Pin interrupt Callback function board buttons configured in the pinTable.
*/
void buttonCallback(PIN_Handle handle, PIN_Id pinId)
{
/* Debounce logic, only toggle if the button is still pushed (low) */
CPUdelay(8000*50);

if (PIN_getInputValue(Board_BUTTON0) == 0)
{

// char input[10];

char buf[10];

// char test;
UART_Handle uart;
UART_Params uartParams;
const char echoPrompt[] = "\fEchoing characters:\r\n";
// test = 0;

/* Create a UART with data processing off. */
UART_Params_init(&uartParams);
uartParams.writeDataMode = UART_DATA_BINARY;
uartParams.readDataMode = UART_DATA_BINARY;
uartParams.readReturnMode = UART_RETURN_FULL;
uartParams.readEcho = UART_ECHO_OFF;
uartParams.baudRate = 115200;
uart = UART_open(Board_UART0, &uartParams);

if (uart == NULL) {
System_abort("Error opening the UART");
}

sprintf(buf,"%d",packet_rx_count);

UART_write(uart, echoPrompt, sizeof(echoPrompt));
UART_write(uart, buf, sizeof(buf));
UART_write(uart, "\n", sizeof("\n"));
UART_write(uart, "hello\n", sizeof("hello\n"));

UART_close(uart);//加上这一句就可以了

}
}

程序有好几处while(1);

为啥一直循环啊

谢谢前面两位朋友提供的信息
