Serial.print prints random 255
hey, i working on mac app control arduino , works if send values 0-63 arduino using following code on arduino: code: [select] void setup() { serial.begin(2000000); serial.print("\n\nhello, rebooted\n\n"); } void loop() { uint8_t incomingbyte[2]; // send data when receive data: if (serial.available() > 0) { for (int = 0; < 2; i+=2){ // read incoming byte: incomingbyte[i] = serial.read(); incomingbyte[i+1] = serial.read(); } serial.println(incomingbyte[0], dec); serial.println(incomingbyte[1], dec); delaymicroseconds(5000); } } the print out should read 0-63 reads is: 0 255 1 2 3 4 ... 62 63 255 the shorter delay put in more 255 appear. idea on happening? thanks -korki why have baud rate @ 2000000? try setting 9600 , see happens....
