In datasheet of 18F458 pag 23 section 3.0 (Reset) thereīs a schematic. I did a little changes to use a switch and make a reset through a switch... Itīs not the first time i'm using this circuit and in the others have been working!

I still prefer the KISS engineering... but it's my own opinion.
how about something like that

you can remove the toggle switch...
In fact to do ICSP i use the above in conjunction with a simple ICSP switcher like that

This allow me to do everything for developpement without install/remove the ICSP connector.

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.

Hi, leonel
Try a Schottky diode ( BAT 85 i.e. ) or Germanium diode ( OA ...) instead of the 1N4148 ... its leakage current will make your reset circuit work better !!!
that's not very elegant ...but will work !!!

What i did and it works was putting a R=100K between pin 1 and ground, in conjunction with my circuit.
What's the "KISS engineering"?
|
Well a pull;-down should be bellow 10K and will affect your current design.
KISS engineering... not meant to be ofendant by any way...of course
Keep It Simply Stupid Engineering.
That's my favorite method.

Everything that avoids a floating pin condition works ....
as Ralf wrote : RTFM !!! ( for humour here ... but found at page 9 or 10 !!! )
