PC Flights A10 Flaps, Hyd Press and Fuel Gauges Help

Kenpilot · May 19, 2021

Does anyone have any of the PC flights gauges for the A10 and uses them with DCS Bios and Arduino? I can't get them to match what the in game DCS gauges are reading. I've looked them up and their values are 544, 2400 and I've messed around with those values in the Arduino sketch but I can't get them to match up for the life of me. If anyone has these and has gotten them to work, please let me know what your values are in your arduino sketches! Thanks!

Hi Ken,

I use a PWM servo driver board for the pcflights fuel gauge, but maybe the values make sense even to your setup.

If not, it could be a way to start from and adjust to your needs.

#define SERVOMIN_R  265 // 6000 lbs for Fuel Qty Right
#define SERVOMAX_R  438 // 0 lbs for Fuel Qty Right
#define SERVOMIN_L  232 // 0 lbs for Fuel Qty Left
#define SERVOMAX_L  420 // 6000 lbs for Fuel Qty Left

Regards, Vinc

Thanks Vinc, I'll definitely give it a shot!

After going back and looking at the arduino sketch, mine looks nothing like yours. Did you get that sketch from the DCS Bios control reference for the A10? Or did you create that sketch on your own?

Vinc_Vega · May 22, 2021

I use a PWM driver board, therefore the sketch is different from yours (example from adafruit).

But as the values were questioned, I was thinking about modify the code like this:

DcsBios::ServoOutput fuelQtyR(0x10cc,PIN, 265, 438);
DcsBios::ServoOutput fuelQtyL(0x10ca,PIN, 232, 420);

My full working code for theA-10 fuel panel with some other connections. Four Servos for LHYd RHyd Lfuel RFuel and a 128x32 0.91" OLED for the total indicator. Enjoy it. You have to set new Values on the servos. I use small gears for 270 degrees rotation.

I've now rolling digits for the total display integrated. Thanks to middlefart. I used code fragments from his altimeter with rolling digits:

Can you modify this just for the oled display so I can test it and tailor it for f-16 fuel total gauge? where is the characters.h file?

Funny thing is I found it...lol. I will post the F-16 Fuel Total Gauge for the display in another thread. Thanks!

Kenpilot · May 22, 2022

I'm back at it again trying to find servo settings to work for my fuel and hydraulic gauges so that they match the gauge readings in the game. I've tried the settings that everyone has suggested so far and none of them have worked. Does anyone else have any suggestions or is there an easy way to figure out what the settings should be for the servos that I have?

Is this of any use:

Do you power your PC Flights gauges from the arduinos? or do you have an external power supply? how much current do the gauges draw?
