sx126x_set_cad_params()函数具体内容

以下是Semtech公司sx126x芯片驱动库中sx126x_set_cad_params()函数的具体内容：

void sx126x_set_cad_params( sx126x_t* sx126x, const uint8_t cad_symbol_num,
                            const sx126x_cad_detect_t cad_detect_mode,
                            const sx126x_cad_symbol_duration_t cad_symbol_duration )
{
    uint8_t buf[3];

    buf[0] = ( uint8_t )cad_symbol_num;
    buf[1] = ( uint8_t )cad_detect_mode;
    buf[2] = ( uint8_t )cad_symbol_duration;

    sx126x_write_command( sx126x, SX126X_CMD_SET_CAD_PARAMS, buf, 3 );
}

该函数首先将CAD参数cad_symbol_num、cad_detect_mode和cad_symbol_duration打包成一个3字节的数组buf，并调用sx126x_write_command()函数向芯片发送SX126X_CMD_SET_CAD_PARAMS命令，将CAD参数写入芯片的寄存器中。

需要注意的是，在使用sx126x_set_cad_params()函数之前，需要首先初始化sx126x的SPI接口，并通过sx126x_init()函数初始化sx126x芯片。除此之外，还需要包含sx126x.h头文件。
