How can that be true? I really cannot understand... A simple cap with a resistor will give the required RC delay. And if you want to quickly reset again, the diode, reverse biased in parallel with...
Ioannis Yesterday, 11:06Anywhere off the mosfet drain or the regulator, it's just a switch
richard Yesterday, 08:40Where would a load go on this circuit (LCDs and other PICs)?
Demon Yesterday, 08:36if you are using 4 bit mode for lcd then the DL bit must remain unset in the command
my code assumes 4 bit mode
to get to lcd mode RE bit must be 0
so more like
lcdout $FE, %00100010...
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...
rocket_troy Yesterday, 05:53Yeah, 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.
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
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.

PIC hangs after interrupt when FT232RL is connected
I bought one of these boards on amazon to help with debugging:

The PIC hangs after the first timer interrupt is triggered. The FT232 is...
