ADF7242射频功率测试无信号，SPI状态读写正常，寄存器读写也正常，就是没有输出。
测试代码如下：
ADF7242_reset();
ADF7242_idle();
ADF7242_FskRate(3);//fsk RF RATE
ADF7242_setMode(0x04); //Set operating mode to GFSK/FSK packet mode
ADF7242_SetFrequency(Channel);//设置信道
ADF7242_syncWord(0x00, 0x00);
ADF7242_cfgPA(15, 1, 7); // Configure power amplifier (power, high power mode, ramp rate)
ADF7242_cfgAFC(80); // Writes AFC configuration for GFSK / FSK
ADF7242_cfgPB(0x080, 0x000); // Sets Tx/Rx packet buffer pointers
ADF7242_cfgCRC(0); // CRC - Disable automatic CRC = 1, else 0
ADF7242_cfgBasicPreamble(); // FSK preamble configuration
ADF7242_PHY_RDY(); // System calibration
// Clear T/R buffer to all 0x00
for(int i = 0x000; i < 0x100; i++)
{
ADF7242_regWrite(i, 0x00);
}
ADF7242_regWrite(tx_fsk_test, 0x22);
ADF7242_regRead(tx_fsk_test,&value);
//ADF7242_PHY_RDY(); // System calibration
ADF7242_transmit();
while(1);
有碰到过这个问题的兄弟吗？ |
