rf_multi_pipe例程¶

1 功能概述¶

rf_multi_pipe演示了RF 297L增强型多通道功能在PAN262xb1_evb上的使用方法。

2 环境准备¶

Board: PAN262xb1_evb多块（另几块烧录不同地址的发送程序）
Micro USB线用于供电和查看串口打印Log
硬件接线：
- 将 J19 开关拔至TX侧，将P3_1与uart的TX引脚相连

3 编译和烧录¶

例程位置：01_SDK\example_basic\rf\rf_multi_pipe

打开目录下keil下的rf_multi_pipe.uvprojx工程，编译整个代码工程，并下载至开发板。

4 演示说明¶

4.1 PIPE0通道接收演示¶

发送端的例程采用01_SDK\example_basic\rf\rf_tx，rf发送地址如下：

RFConfig_t xdata gRfConfig =
{
    /*.Channel        =  */ 2418,
    /*.TxPower        =  */ 7,
    /*.DataRate       =  */ RF_DR_1Mbps,
    /*.ChipMode       =  */ RF_CHIPMODE_XN297,
    /*.WorkMode       =  */ RF_WORKMODE_ENHANCE,
    /*.EnAPL          =  */ ENABLE,
    /*.EnDPL          =  */ ENABLE,
    /*.EnTxNoAck      =  */ DISABLE,
    /*.EnWhite        =  */ ENABLE,
    /*.Crc            =  */ RF_CRC_2BYTE,
    /*.AddrWidth      =  */ RF_ADRESS_SIZE,
    /*.TRxAddr        =  */ {0x10, 0x22, 0x55, 0x0F, 0x71}, 
//    /*.TRxAddr        =  */ {0x11, 0x22, 0x55, 0x0F, 0x71}, 
//    /*.TRxAddr        =  */ {0x12, 0x22, 0x55, 0x0F, 0x71}, 
//    /*.TRxAddr        =  */ {0x13, 0x22, 0x55, 0x0F, 0x71}, 
//    /*.TRxAddr        =  */ {0x14, 0x22, 0x55, 0x0F, 0x71}, 
//    /*.TRxAddr        =  */ {0x15, 0x22, 0x55, 0x0F, 0x71}, 
    /*.RxTimeoutUs    =  */ 1000,
    /*.TxSetupTimeUs  =  */ 200,
    /*.TxBuf          =  */ {0},
    /*.RxBuf          =  */ {0},
    /*.TxLen          =  */ 0,
    /*.RxLen          =  */ 0,
};

编译下载至发送端evb板，收发两端代码运行后可发现接收端在pipe5通道接收到了数据包，抓取接收端部分串口log如下：
