Transmitting interger to VGAX code then stops after 1 loop

why-a-cloak-007 · November 8, 2023, 9:19pm

I have two mega2560 boards, 1 sends a interger to the other and it connects to a VGA screen and displays the info, but after receiving the data and displaying it, the code doesn't save the value and runs the loop one more time without displaying the data and then the VGA display gets scrambled, but when i send it data again it repeats the process again, receives data then displays it, then displays no data, then VGA scrambles again.

Here is the sketch that sends the data, its just a integer.

#include <SoftwareSerial.h>
int datain=0;

void setup()
{
  Serial1.begin(115200);
  Serial.begin(115200);        
}

void loop()
{
  if (Serial1.available())
  {
    dataIn = Serial1.parseInt();
    Serial.println(dataIn);//monitor data from PC
    Serial1.println(dataIn);//send data to mega
  }
}

The VGA sketch is here

#include <SoftwareSerial.h>
#include <VGAXUA.h>

So, why not just fix the problem? Or find the person who wrote the code and tell them of the error.

why-a-cloak-007 · November 9, 2023, 4:38pm

I wrote both codes while looking at examples of other codes that used VGA examples and the VGA library. Something is happening in the background that I don't recognize, I need help identifying it and help fixing it.

Paul_KD7HB · November 9, 2023, 5:21pm

Create a new global, integer, variable and save the data.

why-a-cloak-007 · November 14, 2023, 8:51pm

I added a global interger and it doesnt fix it, the digit shows on the VGA then the VGA displays again without the digit then the VGA display starts to half fade or fill with rand lines. here is the code
