Working sketches - for reference

[lesthegrngo]

Guys, if you are like me and are pretty useless with coding on DCS Bios, then you are probably searching desperately for working sketches that you can copy.

 

So, I have decided to put this thread in when I get sketches that work, and with details of what I have used with it so that you can hopefully replicate it with no effort. It's about time I gave something back to the forum!

 

So, first up, I have got an LCD 1602A module like the one in the attached photo, which has the PCF8574 'backpack' attached that reduces the number of pins from 16 to just 4.

 

You need to install the LiquidCrystal_PCF8574 library ( https://github.com/mathertel/LiquidCrystal_PCF8574 )

 

The pinout from the Arduino to the PCF8574 backpack board is as follows

 

Arduino GND pin to PCF8574 GND pin

Arduino 5v pin to PCF8574 VCC pin

Arduino A4 pin to PCF8574 SDA pin

Arduino A5 pin to PCF8574 SCL pin

 

This sketch works with the above replicating the CMSC panel via USB

 

 

 

#include <Wire.h>

#include <LiquidCrystal_PCF8574.h>

#define DCSBIOS_IRQ_SERIAL

 

#include <DcsBios.h>

 

LiquidCrystal_PCF8574 lcd(0x27); // set the LCD address to 0x27 for a 16 chars and 2 line display

 

int show;

 

 

void onCmscTxtJmrChange(char* newValue) {

lcd.setCursor(0, 0);

lcd.print(newValue);

}

DcsBios::StringBuffer<8> cmscTxtJmrBuffer(0x1096, onCmscTxtJmrChange);

 

void onCmscTxtChaffFlareChange(char* newValue) {

lcd.setCursor(4, 0);

lcd.print(newValue);

}

DcsBios::StringBuffer<8> cmscTxtChaffFlareBuffer(0x108e, onCmscTxtChaffFlareChange);

 

void onCmscTxtMwsChange(char* newValue) {

lcd.setCursor(0, 1);

lcd.print(newValue);

}

DcsBios::StringBuffer<8> cmscTxtMwsBuffer(0x12b0, onCmscTxtMwsChange);

 

void setup() {

lcd.begin(16, 2);

lcd.clear();

DcsBios::setup();

 

}

 

void loop() {

DcsBios::loop();

lcd.setBacklight(255);

}

 

 

 

 

 

hope this helps

Very helpful stuff.

 

These forums aren't great for code though. I'd suggest using Gist and then just linking them, as it will handle the code a lot better.

 

Here is your last example, the radio panel for example:

https://gist.github.com/jwvanderbeck/1d53fa5ed17917fced92c3212de117f9

 

I'll definitely be looking at that one as the first panels I want to make are tacan and radio since those are the worst in VR. Don't need a display though :)

Hi Les,

 

 

Do you see any effect when using a value of 10 in "lcd.setBacklight"?

Is the Display's backlight more dimmed as if using the value 255 (like in the cmsc sketch)?

If you only want to switch the backlight (without dimming) just use: "lcd.backlight();" in the setup loop.

For dimming the backlight I think a PWM pin from the arduino has to be used.

Edited June 16, 2019 by Vinc_Vega

[lesthegrngo]

No, Vinc, you are right in that the value after the lcd.setBacklight seems to have no effect - the original value was 255, but I was playing around with it on later sketches, and as it seemed to have zero effect I just left it as it was.

 

If there is a line of code to affect it, it would be interesting to know, maybe include it for future sketches?

 

Cheers

 

Les

[Vinc_Vega]

I dont think dimming is possible via the PCF Chip. I use a PWM signal (eg. Pin 5) connected to the Background LED of the LCD. Instaed of direct connecting I use a small FET (2N7000) and the analogWrite() function to control brightness of the LED.

ILS panel via USB

Using a 1602A LCD panel with a PCF8574 this is the sketch for outputting the ILS and displaying the 5 character set plus decimal point frequency data on the bottom line

 

It also has two frequency control dials plus the on-off switch mapped to rotary encoders. Hopefully future versions will have the volume control mapped to a rotary encoder too, but at the moment I can't seem to make it work

The proper way to display code on the forum is to place it between characters that show up when you check the # in the menu above. That way you don't have to include a .txt file. This is what you will get by doing it the correct way and it makes it easy to copy the code and paste it into another app... IDE.

Thanks WarHog, HanSolo also gave me that tip, will use it from now on - will also go back an d edit the original posts to make sure of consistency
