A10 CMSP Display Arduino Sketch?

[Kenpilot]

Building the A10 CMSP and using an Arduino Mega and IIC / I2C 2002 20x02 OLED Module Display. Anyone care to be kind enough to share their Arduino sketch for the display?  I'm clueless when it comes to writing them for displays. Thanks!!

Do you mean somethin like that?

// first charracter line on CSMP display
void onCmsp1Change(char* newValue) {
      lcd.setCursor(0,0);
      lcd.print(newValue);
}
DcsBios::StringBuffer<19> cmsp1Buffer(0x1000, onCmsp1Change);

// second charracter line on CSMP display
void onCmsp2Change(char* newValue) {
      lcd.setCursor(0,1);
      lcd.print(newValue);
}
DcsBios::StringBuffer<19> cmsp2Buffer(0x1014, onCmsp2Change);

Regards, Vinc

That looks about right, thanks Vinc! I'm still building the panel but I'll test it out once I finish it. Thanks again!!

Thank you for this code. This is useful, but requires additional libraries. Which libraries do I need to specify to work with this display (OP202i IIC / I2C 2002 20x02 OLED Module Display) and export using https://github.com/DCS-Skunkworks/dcs-bios? If you have a complete sketch, could you share it?

It may have the SSD1306 chip, try this library to talk to your display:

@Kenpilot Thank you very much for your sketch! I think I'm doing something wrong. I have installed these libraries:

https://github.com/DCS-Skunkworks/dcs-bios-arduino-library
, but I still get an error when compiling:

Very strange: I found library OLedI2C.h but maybe it is not for op202i 20x2 display. 8-( Can't make it works. 8-(

[Rapti]

We use this display. Don't know if its the same than yours.
IIC / I2C 2002 20x02 OLED Module Display

Our Code: 

this work on our side.

#define DCSBIOS_DEFAULT_SERIAL

#include "DcsBios.h"
#include  "Wire.h"    
#include  "OLedI2C.h"  
OLedI2C LCD;

/* paste code snippets from the reference documentation here */
void onCmsp1Change(char* newValue) {
   LCD.sendString(newValue, 0, 0);
}
DcsBios::StringBuffer<19> cmsp1Buffer(0x1000, onCmsp1Change);

void onCmsp2Change(char* newValue) {
   LCD.sendString(newValue, 0, 1); 
}
DcsBios::StringBuffer<19> cmsp2Buffer(0x1014, onCmsp2Change);


void setup() {
 DcsBios::setup();
   Wire.begin();
 LCD.init();  
}

void loop() {
 DcsBios::loop();
}

Can you post your sketch? Looks like something going on with DcsBios. Do you have the latest DcsBios library?
