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:

RCEXL Tachometer (hardware) with my own alternative firmware (software) (0 min 12 sec)


Any comments or suggestions are welcome.

You are right, thanks for info. I overlooked that length of URL address was automatically reduced. The first link is also valid now.
