Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Subs, pages 160-161

1. Seems Duplicated paragrapgh.
2. Seems Duplicated but edited.

If duplications removed, TEMPR START would not be split across pages 161-162 as it is difficult to follow read.

@Peter, Geoff, thanks for this release.

So far everything works fine.
One problem I ran into was the disruption of the I2C bus because I use old Arduino hardware like LCD displays 4x20 with an I2C module and no pullup resistors!
Mount the pullup resistors directly to the GP pins to 3V3. It turns out that the current bus speed is too high for these modules. (400KHz)
So I lowered the speed to 100KHz and it works fine so far.
OPTION SYSTEM I2C SDApin, SCLpin, SLOW

Greetings,

Jan.

I'm pretty new to the PicoMite and have just built out a VGA/USB system on breadboards. I have to say I'm loving it and thank you for the new firmware. Some nice improvements!

Question: where do I get the "help.txt" file for the help command to work and what do I do with it?

Thanks.

if you want something more solid than your breadboard solution, I recommend the PicoMiteVGA Construction Pack:

Hi ManiB,

Yes, that is the grand-dad of all the stand alone pico basic computers.

There is also a VGA design 2, where audio is added, and the optional RTC (and breadboarding footprints). I started, and still love, VGA design 2.


In this photo a breadboard footprint is used for a second pico, that runs a chess program. The main pico is for display of the chess board, and keyboard interface.
The "breadboard sockets" are very nice for playing with interfaces (like the SSTV interface, the MORSE interface, etc...).

Note that VGA design 2 is just an extended VGA design 1. Just RTC and Audio added (and the breadboard footprints).

If you desire to retro-fit audio and RTC in VGA design 1 added later on, Peter made a piggy-back board for that, I think the design files are on this forum.

Where are the details for this ?. I'd love something full featured that can fit in a small case with keyboard and touch screen plus lots of free i/o, space for several additional modules, holes for mounting a heatsink on the processor and dual 18650 batteries !
