A-10 UHF Values to 3.5in Arduino Diplay

[Rapti]

Hello friends, maybe someone can help me here. I want to show certain values of the UHF on a display in my A-10 cockpit (for example the preset). The display is a 3.5in Arduino display.

I must confess that I have little idea of DCS programming and do everything by Try&Error. I wrote the following program which writes the static text and graphics to the display. For the output of the preset channel I have the following code in DCS BIOS:

 

void onUhfPresetChange(char* newValue) {

/* your code here */

}

DcsBios::StringBuffer<2> uhfPresetBuffer(0x1188, onUhfPresetChange);

 

If I include this in my code then nothing happens in the display.

The code compiles without any problems

Could someone go over the code for a moment and tell me if I have a general problem in the code?

I can't get it to work either, and my character LCD display is showing the values changing, so it's not DCS.
Your code is too complex for me to fault-find this evening.
Maybe you should start over and make it modular to begin with.
Get it displaying a simple value changing first, then go into the fancy formatting.

Try to remove or comment the "Serial" statements within the Setup loop.

both of them?

Yes, both "Serial" statements as they may disturb the communication managed by DCS-Bios.

I just tried the OP sketch without those two lines and it now displays the changing number. Good call, Vinc. 

I would still suggest a rewrite in modular form, though.

Thanks for the reply

The Serial protocol seems to conflict the DcsBios communication. For debugging I mostly put Bios commands within compiler switches to separate them from Serial commands.

See below for your imagination.

// #define TEST  // uncomment for testmode

#ifndef TEST
  #define DCSBIOS_IRQ_SERIAL
  #include "DcsBios.h"
#endif

...


void setup() {
  
#ifdef TEST
  Serial.begin(115200);
  Serial.println("Booting...");
#endif

#ifndef TEST
  DcsBios::setup();
#endif

...

void loop() {

#ifdef TEST
run_display_test();
#endif

#ifndef TEST
  DcsBios::loop();
#endif

...

I usually send to an I2C character LCD for debugging.

Hi Vinc, thanks for your help. Works great!

thats the new code:

This was great. I tweaked it a little since it didn't seem to fit correctly on the elegoo tft display I have, I switched to all green/black as a matter of personal preference, and did some slight rearranging. https://pastebin.com/cS9vv56W
