您好,看到了您issue,我最近也在研究这个单片机的Serial,问一下您使用Serial1的时候能正常的接收数据吗?我尝试好长时间都收不到,发送倒是正常
Can not reproduce any problem with the following code.
extern __xdata uint8_t LineCoding[]; //lineCoding of CDC is located in this array
__xdata uint32_t oldBaudRate = 9600;
void setup() {
Serial1_begin(9600);
}
void loop() {
if (USBSerial_available()) {
char serialChar = USBSerial_read();
Serial1_write(serialChar);
}
if (Serial1_available()) {
char serialChar = Serial1_read();
USBSerial_write(serialChar);
}
__xdata uint32_t currentBaudRate = *((__xdata uint32_t *)LineCoding); //both linecoding and sdcc are little-endian
if (oldBaudRate != currentBaudRate) {
oldBaudRate = currentBaudRate;
Serial1_begin(currentBaudRate);
}
}
编译示例文件USBSerialAdaptor的时候,使用Serial0可以正常使用,但是切换为Serial1的时候,不能正常收发数据, 主要是想使用CH552E的MSOP10小封装,只有Serial1可用
