各位大侠，小弟最近在使用ax5051射频芯片进行收发通讯，目前遇到下面两个问题：
1、接受每次开机接收数据的时候都要重新软件复位才行，不知道是什么原因。 2、在发送完转化接收的时候前面两包数据会丢失，收不到数据，不知道什么原因造成的，有大神是否愿意指导，如果方便也可以进行合作形式。谢谢！！ 代码如下： #include #include #include #include #include #include #include "../COMMON/uart.h" //#include "../COMMON/adc_example.h" /*********定义AX5051PWRMODE寄存器各种模式*****************/ #define POWERDOWN 0 #define VREGON 4 #define STANDBY 5 #define SYNTHRX 8 #define FULLRX 9 #define SYNTHTX 0X0C #define FULLTX 0X0D #define ADC_BUFFER_SIZE 40 #define TX_PREAMBLE 29 /*************定义DMA相关的参数*************/ struct DMA_descriptor{ void __xdata *bufaddr;
