Hi to all!
Like Vlado, i'm developping a board on my kart 125 shifter that cut-off the electric current of engine coil to permit me to shit without close the gas pedal.
And like Vlado, i have the same problem: after few seconds (with the engine on) the arduino resets!
So, reading this post i decide to apply the reset protection.
Both of these changes are implemented on all of my boards. http://www.wiblocks.com
1. I use a 10uH, 0.1uF low pass filter.
2. For the reset I have a 1N4148 from the reset pin to Vcc. I also include
a position of a 0.1uF cap from /RESET to GND. (NB If you use the
0.1uF from /RESET to GND the /RTS on close reset will not work
(* jcl *)
But i have a trouble with the 0.1uF cap from reset to gnd... After applying the cap the board come into a reset-loop status...
If i apply the cap after the first boot, the sketch start and anything go ok. But if i start the board with the cap mounted on, in this case it appen the condition described...
Any suggestions? Thanks a lot!
