RCEXL tachometer - alternative firmware
I made successful test with (new my own) alternative firmware into original hardware. Programming was via ICSP. Main difference is using all 4 digits for RPM value - the range must be lower, approx. 1000-9999. (this means x1, not x10). My gas engines are happy with this range, they don't need 10k or more The second difference is the addition new function: max. RPM - is shown approx. 3x per min.
I suppose that hex file or source code (maybe) I will publish it for all who is interested. Here are 2 videos:
Any comments or suggestions are welcome.
more info about tachometer is now on web:
direct hex file is not possible to upload here and zip file you can download from web:
