用2-FSK模式可以正常收发，下面是我2-fsk的配置
//基频：432.6M FREQ2 FREQ1 FREQ0
//前导字节为2个 MDMCFG1
//better sensitivity MDMCFG2
//Data rate:110 kBaud MDMCFG4 MDMCFG3
//RX filter BW: 325 KHZ MDMCFG4 MDMCFG3
//Deviation: 47.6KHZ
//Modulation format: 2-FSK
//Channel number: 0x0f
const RF_SETTINGS rfSettings = //channel number变了
{
0x00, //FSCTRL2;
0x08, // FSCTRL1 Frequency synthesizer control.

};
改成ask模式后，就不能接收了，试过很多速率，带宽等的不同配置，都不能接收成功，也阅读过N022的说明文档，对 MDMCFG2和 FREND1是做过相应修改的，通过调试后发现，当调用 halSpiStrobe(CCxxx0_SRX);//进入接收状态，
void halSpiStrobe(INT8U strobe)
{
CSN = 0;
while (MISO);//为低电平说明晶振开始工作
SpiTxRxByte(strobe); //写入命令
CSN = 1;
}
就卡在了while (MISO);//为低电平说明晶振开始工作
不能在往下执行了，下面我列一下我的一张ask的配置
const RF_SETTINGS rfSettings = //channel number变了
{
0x00, //FSCTRL2;
0x02, // FSCTRL1 Frequency synthesizer control.频率合成器控制 中频？？？ 04还是09 0D 怎么算???
0x00, // FSCTRL0 Frequency synthesizer control. 1
0x10, // FREQ2 Frequency control word, high byte. 1 决定基频 可以根据说明文档计算得到
0xA5, // FREQ1 Frequency control word, middle byte.
0x6A, // FREQ0 Frequency control word, low byte.???
0xf5, // MDMCFG4 Modem configuration. 调制器配置 由接收滤波器带宽和波特率共同决定
0x83, // MDMCFG3 Modem configuration.????? 调节波特率
0x33, // MDMCFG2 Modem configuration. 模式选择,是否使用曼切斯特编码，传输同步字节设置 33还是3b
0x02, // MDMCFG1 Modem configuration. 高四位决定前导码的最小位数 低四位 指数的频道间隔

};
网上的很多关于ask配置的例子，我也试过，都不能接收，求大师们帮我看看是什么原因，自己实在分析不出来了
