Serial Communication - Parity Problem - missing zeros
Posted: Sat Aug 14, 2021 4:49 amHello ESP Friends, i am in trouble with the serial port settings of my ESP8266.
the 8266 serial port is configured to: 2400, SERIAL_8E1
the expected hex values would be: 68FAFA6853FF000167DB084B464D...............
the hex values i get: 68FAFA6853FF0167DB84B464D.......
so, there are missing "0" - for example after FF, after DB ....
the test prg i use:
It seems the Parity Configuration would be ignored.
The right HEX Values I got from a python Prg on the Raspberry Pi.

Code: Select all
/*
ESP8266 Serial Communication
*/
void setup() {
Serial.begin(2400, SERIAL_8E1);
}
// the loop function runs over and over again forever
void loop() {
if(Serial.available()>0) //Checks is there any data in buffer
{
Serial.print(Serial.read(),HEX); //Read serial data byte and send back to serial monitor
}
else
{
Serial.println("\n");
delay(1500); // Wait
}
}It seems the Parity Configuration would be ignored.
