But these solutions are above my skills for now. When I look at Leo Bodnar's USB load cell interface, it seems a bit complex. Someone in this topic would try using those techniques maybe. Cheers all!
  2. Hi all! Thank you Alexey! Everything works now. Now I wonder why our DIY pedals have apparent interference noise? As I see from your, and other guys videos, you have that too. When I watch videos from Sim Racing Garage, all proffesional pedals look so smooth on their calibration screens. They are not using special cables or connectors. I used 0.22uf capacitors at first, there was heavy noise. I kept searching about noise and found that information on a forum: Now I use 100uf caps: https://electronics.stackexchange.com/questions/591849/minimize-load-cell-amplifier-noise-and-interference-ina122p I also tried 47uf, 470uf and 1000 uf. But after 100uf, there was not a noticeable improvement. So I kept 100uf caps on all 3 pedals. Video of my calibration screen (clutch pedal is dismounted. Axis 1 throttle, axis 2 brake): https://drive.google.com/file/d/1Ae_bYKV_8YsdbNuA9ggUdfZYK7rfo_F4/view?usp=sharing
  3. Hello to everyone. Alexey I especially want to thank you. (I've read all messages. Maybe I have faulty or fake chips but i don't know for sure. My measurements are in pictures at the bottom link. I'm about finishing the pedals. I soldered all the components to the PCB. There are AD627 SOIC chips. I uploaded opensimhardware hex file to STM32. I then soldered the STM32 to the PCB. (5v, 2xGND, 3xOutput pins) But in this case, when I connected it to the PC via USB, the PC did not recognize it. I also noticed that the LED of the STM32 was not lit and the USB inputs and outputs as well as the GND and 5V bridge cables were hot. The chips did not get hot at all. GND and 5V were short-circuited when I checked with my multimeter. I've desoldered STM32. It is running now and has the program in it. I did a diode test on the chips.The values are the same for all 3 chips. I bought new chips from another store (AD620 this time), they seem to have those similar values when i check with multimeter. What should be the readings of these type analogue chips in normal condition when I check with the multimeter? What could be the problem? Thanks again. Link to pictures (imgur)
