im sending the value 1500 from another MCU with
fdserial_txChar(transmit, send >> 7); // send Higher 7 bits
fdserial_txChar(transmit, send & 0x7F); // send Lower 7 bits
and was receiving it with code that looked like this
servo1 = fdserial_rxChar(receive) << 7; // get Higher 7 bits
servo1 += fdserial_rxChar(receive) & 0x7F; // get and add Lower 7 bits
how do i rewrite the receiving code so arduino will compile it?
Thank you.
here is the code im trying to get working
void setup() {
// physical pin 2=TX 3=RX
Serial.begin(9600);
pinMode(3, OUTPUT); // set LED pin as output
digitalWrite(3, LOW); // switch off LED pin
}
void loop() {
if (Serial.available()) {
// char data_rcvd = Serial.read(); // read one byte from serial buffer and save to data_rcvd
int data_rcvd = Serial.read() << 7; //get Higher 7 bits
int data_rcvd += Serial.read() & 0x7F; //get and add Lower 7 bits
if (data_rcvd == 1500) digitalWrite(3, HIGH); // switch LED On
if (data_rcvd == '0') digitalWrite(3, LOW); // switch LED Off
}
// if (digitalRead(8) == HIGH) Serial.write('0'); // send the char '0' to serial if button is not pressed.
// else Serial.write('1'); // send the char '1' to serial if button is pressed.
}
