PicoMiteVGA: Raspberry Pi Pico Boot-to-BASIC Microcomputer

Күн бұрын

PicoMiteVGA boot-to-BASIC computer built from a Raspberry Pi Pico using the circuit designs and code available on Geoff Graham’s website here: geoffg.net/picomitevga.html The PicoMiteVGA was created by Peter Mather, Geoff Graham and Mick Ames, also building on work by Miroslav Nemecek, as detailed on the aforementioned page.
My previous video about the PicoMite, where we look in more detail at MMBasic and GPIO control, is here: • PicoMite: Running BASI...
There are a number of cool, short videos demonstrating various aspects of PicoMite VGA on Peter Mather's channel here: www.youtube.com/@petermather3...
The Siliconchip PicoMiteVGA kit that I could not order in the UK, but which looks excellent, is here: www.siliconchip.com.au/Shop/2...
If you wish to build a PicoMiteVGA, everything you require is available at geoffg.net/picomitevga.html However, I have shared the STL files for the solderable breadboard brackets I created here: www.thingiverse.com/thing:575... And my breadboard layout is here: www.explainingcomputers.com/i...
For information, the parts I ordered from Pimoroni and CPC Farnell were as listed below. Please note that I have no association with either company.
MicroSD card breakout: shop.pimoroni.com/products/br... -- also available from Pololu here: www.pololu.com/product/2597
Raspberry Pi Pico H: shop.pimoroni.com/products/ra...
Female headers to mount Pico: shop.pimoroni.com/products/pi...
2N7000, TO92 package MOSFET -- two required:
cpc.farnell.com/microchip/2n7...
1N4148 TR diode (100V, 200mA) -- two required, but minimum order quantity of five:
cpc.farnell.com/on-semiconduc...
Trimmer (trim pot), 25 Turn 200R - 3296W-1-201LFx1:
cpc.farnell.com/bourns/3296w-...
100 nF capacitor, one required, but minimum order quantity of five. This is a bypass capacitor for the SD card wiring, and as explained in the video, in the end I did not need to fit it. But you may need to add one of these capacitors for stable SD card operation:
cpc.farnell.com/multicomp/mcr...
15-pin D-Sub (VGA) socket:
cpc.farnell.com/itw-mcmurdo/h...
Mini DIN 6-pin (PS/2) socket:
cpc.farnell.com/pro-signal/ps...
Large perfboard (solderable breadboard):
cpc.farnell.com/sparkfun-elec...
Reset switch -- the one I had in stock was very similar to this:
cpc.farnell.com/multicomp/r13...
I also has in stock the required resistors, namely:
220Ω resistors (red, red, brown, gold), 0.25W or higher -- seven required.
10KΩ resistors (brown, black, orange, gold), 0.25W or higher -- four required.
Buying resistors like this individually is hard! These are the cheapest packs of these values I could find on CPC Farnell:
220Ω - cpc.farnell.com/unbranded/mcf...
and
10KΩ - cpc.farnell.com/unbranded/mcf...
Also used were eight M3 nuts and bolts, about 12mm long, and some wires. I actually cut up a Pimoroni jumper pack, as again buying a lot of different wire colours in small quantities is difficult: shop.pimoroni.com/products/ju...

There's already someone who turned the pico into a micro C64 with a tiny 320x240 display and hand-made mini keyboard/joystick. VGA timings and data were generated on-the-fly too due to lack of memory for a frame buffer. He's on YT somewhere just can't remember the channel name. It was an impressive little thing and nicely done too. I suppose it's not really hard to make a frame buffer out of an external 256 or 512 k memory chip. SOmeone will be working on that right now I expect, or even finished it.

@petermather3049 Жыл бұрын

The PicoMiteVGA has a framebuffer and the option of adding two extra framebuffers in Basic memory. One of them acts as an overlay area allowing objects to move over a background and the other can be used to get artefact free updates by copying it to the main buffer during screen blanking

Generally valid advice for both software and hardware: build it in the smalledt possible stages, test after each, and if it stops working, the cause is whatever you just did, In interesting challenge would be to fold up the design into as small a form factor as could be conveniently constructed, preferably in a generally-available container. The sockets would likely be the major constraints there. It could be a way to build test points into a larger system or piece of machinery, if a Wifi data stream isn't suitable for some reason.

Greetings from across the pond near Albuquerque, New Mexico. This video reminds me of my Radio Shack TRS-80, including the expansion interface containing an extra 32KB of memory to add to the original 16KB internal memory. Many people trashed the TRS-80, but not me -- I learned BASIC, good programming techniques, some assembly language programming for the Z80 processor, and even had a Fortran compiler for it. Had a Radio Shack dot matrix printer to go with it, too. Even the computer table came from Radio Shack. My boss had one too, so it made for great collaborations. We routinely ran 6-degree-of-freedom ballistic trajectory simulations in BASIC for work. Fun times! Oh to have an RP2040 dual-core 133MHz processor back in the late 1970s / early 1980s era. This video also reminds me how thankful we should be for USB, HDMI, Bluetooth, wireless and wired networking, gigabytes of on-board memory, terabytes of external storage, multi-core processors (still admire the Z80 processor, though), SBCs, 8K resolution, etc. Absolutely great video. Well done, Prof. Barnatt! 😀

Well, the PICO has only two cores. So one for VGA and one for your code. Sound could be another option. But that could probably be handled by the PIO's. The RP2040 in the PICO is a great MCU.

Thanks Chris for a very interesting video. This takes me back to the 80's, following circuit diagrams, soldering components (neatly) to a pcb the correct way round. The components were really cheap & more easily accessible back then.

Are you sure they were really cheaper back then? The prices and availability in the modern, global electronics market are generally better (at least pre Covid). The low cost microcontroller and SBC markets are incredible. The fact you can pick up a Pi Pico for around £5 is amazing.

@@another3997 I totally agree with you a Pi Pico for £5 is amazing. The components were cheap in the early 1980's, that's how we built a lot of projects back then! The things that were expensive were micro-computers i.e The Sinclair ZX81 an introductory kit in 1981 was £49.95 which would equate to £204 ($279) in 2023. The BBC micro model A was £235 & the Micro model B £335 in 1981 & equates to £1152 (A) & £1642 (B) today, how things have changed.

brilliant video. thanks now got another project to do :) these picos are such fun to tinker with

Awesome! I love the picomite but was pumped to see a stand-alone version that didn't need another computer to run

I will have to try this. I have Color Maximite 2 and love it.

This was a great video, lots of info. I like your simple bread board solution, thought it rather genius in its simplicity and very available from many sources for fairly cheap. Thanks!

This is a great build! It helps solidify some ideas for emulating an Apple II with a Rpi Pico. Thanks.

I just sit here thinking it's cool AF! Christopher, you're the man! Edit: That handling of VGA signal is a game changer. As a person who toys with Arduino/ESP32/Raspberry, i know that making of clear interference can often defeat the sole purpose of the prototype's existence. This bypasses the issue entirely and allows newbies to get sucked in seeing the potential of their projects without going through (often) painful design and implementation of the interface.

Really good video, really good introduction to basic electronics, good project for that. Really good example of using a solderable breadboard instead of a PCB. It's awesome that you can hook up ordinary PC peripherals to a microcontroller.
