12.000m的晶振,22pF的独石电容,5脚用104的独石电容接地。应该没问题啊,可是CH372就是不产生中断信号,初始化函数放下面:void Init_CH372(void) { uchar8 a; // Write_CMD_CH372(CH372_CHK_SUSPEND);//设置CH372的挂起检查方式 // Write_Data_CH372(0x10); // Write_Data_CH372(0x04); Write_CMD_CH372(CH372_SET_USB_MODE);//外置固件模式 Write_Data_CH372(0x01); do { a=Read_Data_CH372(); #ifdef DEBUG_CH372 Prints("The Operator Status is:"); PrintHex(a); Prints("\r\n"); #endif } while(a!=CH372_RET_SUCCESS); //while(Read_Data_CH372()!=CH372_RET_SUCCESS); }
