Re: Graphical Displays with PBP3

Haven't tried 1st suggestion yet, but I've been playing around with your 2nd suggestion... well... I can't find a datasheet for my displays so I've been playing the old game of finding a ST7920 DS...

Re: Complete circuit RESET

Yeah, that would work, but I thought this was cool with the delay. :D

And I've never touched a 555 or 7404, so it was a learning experience.

Re: Complete circuit RESET

seems an awful lot of circuitry to achieve not a lot, would it not be easier to turn it off, count to 3 turn it on again :D

for all that work i would expect at least a single button on/off facility

Complete circuit RESET

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.

Re: Graphical Displays with PBP3

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...

Re: Graphical Displays with PBP3

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...

Re: What is the difference between MCLR and switching VDD OFF-ON?

Got a complete system reset working with a 555 timer, 7404 inverter and IRFZ44N mosfet:

Re: System RESET works, sort of

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...

Re: System RESET works, sort of

I tried this guy's idea of a RC delay on the mosfet.
