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.

AMICUS

What is Amicus18?

Amicus is a multifunction development system inspired by the popular Arduino board, however, the Amicus board uses a Microchip PIC^® microcontroller instead of an Atmel AVR^tm type.

Comprehensive documentation and a helpful and friendly support environment, make using Amicus18 an easy and enjoyable experience for beginners and seasoned programmers.

Forum Moderator Mackrakit (Dave) very kindly ported the Proton BASIC Compiler code over to PBP3 and modified the original AMicus18 docuemts for PBP3 users.

Companion Sheild

The entry level shield is labelled The Companion Shield. This is a PCB laid out in the pattern of a solderless breadboard. The holes are single sided, which means that components can easily be removed using solder mop braid, or a solder vacuum tool, if a mistake is made, or components need to be re-used.

The (PBP3) Companion Shield Manual iCan be downloaded from here

GPS Shield

The Amicus GPS shield contains a multi channel GPS receiver, as well as a 16k byte (128 kbit) serial (I2C) eeprom, and a 3 Volt, 12mm battery socket in order to maintain the receiver's built-in RTC (Real Time Clock).

Available in our on-line store
