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 (prototype with alternative firmware) (0 min 47 sec)

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.
