MY system is windows, and my board is arduino mega.
i want to use the uart3(TX3,RX3) to communicate with another component.
my code is:
int buf[]={FF FF 00 07 03 1E 00 02 00 02 D3};
void setup(){
Serial3.begin(500000);
}
void loop() {
Serial3.write(buf,11);
}
but its said"27: error: exponent has no digits".
What can i do? I am a beginner, and I need the help of yours. Thanks!
