hi guys, I have an error in this code. I want to send the hex bytes and receive the same bit long data serially...kindly help me
void setup() {
// Turn the Serial Protocol ON
Serial.begin(9600);
}
void loop()
{
byte message[] = {0xA5, 0x0D, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,0x00, 0x0d };
Serial.write(message, sizeof(message));
if (Serial.available()) {
byte byteRead[] = Serial.read();
}
}
See the Serial Input Basics thread and don't hijack this one.
Hi guys, I have an issue with this code. I want to send some hex value serially and expecting to receive the
same kind of data serially but I receive some garbage values on the serial monitor. I also select the same baud rate. Any help will be appreciable. Thanks,
const byte numChars = 88;
char receivedChars[numChars]; // an array to store the received data
boolean newData = false;
void setup() {
Serial.begin(9600);
Serial.println("");
}
void loop()
{
uint8_t message[] = {0xA5, 0x0D, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,0x00, 0x0d };
Serial.write(message, sizeof(message));
recvWithEndMarker();
showNewData();
}
void recvWithEndMarker() {
static byte ndx = 0;
char endMarker = '\n';
char rc;
while (Serial.available() > 0 && newData == false)
{
rc = Serial.read();
if (rc != endMarker) {
receivedChars[ndx] = rc;
ndx++;
if (ndx >= numChars) {
ndx = numChars - 1;
}
}
else {
receivedChars[ndx] = '\0'; // terminate the string
ndx = 0;
newData = true;
}
}
}
void showNewData() {
if (newData == true) {
Serial.print("data ");
Serial.println(receivedChars);
newData = false;
}
}
