I have the idea for several years but could never get the project started. I then found this website and downloaded the code editer and manuals. After 2 days of tinkering on my down time I was able to write some code to control ride hieght based on vehical speed.
I want to use the 20M IC and us the 4 adc channels to control 5 output pins. Everything works as I like on the simulator. Trying to design a PCB to house the processor and a freq to volt converter for vehicle speed and other hardware.
Can someone read through my code to see if there is anyway improve it? Any feed back on the project as a whole would be great.
The idea is to use 2 TPS type sencors, one placed on each axle and a pressure sender on the air tank, based on adc counts I can turn on or off 5 relay inputs. Compressor relay, front up, front down, rear up and rear down.
All the adc counts listed in the code will have to change once installed in the car of course. Any advise would be great Thanks Ryan
