First of all, thanks for this code and schematic! I have modified it to also display separate color patterns at lower rpm's and as my first arduino project I am thrilled that it is working great! I have it up and running on my bench and it's working, but the shift rpm is constrained to be under 7650rpm but my car red lines at 8600rpm, how can I adjust the code to allow for higher shift rpm settings? I feel like it's something super simple I'm overlooking but I cant find where the maximum for the shift rpm is defined. Thanks!
So I found where the variable is set in the menu for shift rpm:
r2 = constrain(r2, 0, 255);
and if I change the 255 to 290 it allows me to display the rpm range I want (290*30=8700 which is right around where I want the shift rpm) but it wont save any value over 255 (displayed as 7650) and just saves a really low value like 29 (displayed as 870). How can I fix this issue? again, thanks for the help!
