The purpose of this circuit is to provide sufficient time for the PICs and LCDs to make a complete reset once powered down and back up. 9797 Thread and video: ...
does it make a difference if you power it down verses a reset >\? also if you look at the data sheet you can see what commands are needed to make a routine to revert to lcd mode, do a clear screen...
No luck. Maybe 1 in 10 starts I still get the zeros. Tried increasing the DEFINE LCD_COMMANDUS 1000 to 1500 and DEFINE LCD_DATAUS to 100 and inserted the code you suggested. I didn't mention I need...
Got a complete system reset working with a 555 timer, 7404 inverter and IRFZ44N mosfet: https://www.picbasic.co.uk/forum/showthread.php/26810-System-RESET-works-sort-of?p=156426#post156426

GOT IT! Reinstalled the 555 timer with 7404 inverter. I had to up the capacitor to 100uF. Works beautifully with 10K. Just over a second (by eye), so now I can blip the button and reset is...
I tried this guy's idea of a RC delay on the mosfet. https://electronics.stackexchange.com/questions/322142/how-to-implement-a-delayed-release-for-a-reset-button/322184#322184 I tried with...
Nope, no difference.
Maybe you just need a cap in parallel of the button and a diode in parallel with the resistor, cathode to +Vdd. 10uF would be a good start. Ioannis
