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.

Forum Index : Microcontroller and PC projects : PicoBoy might be of interest

Hi there,

I found this product through a magazine article at GOLEM (https://www.golem.de/news/picoboy-im-test-dieser-lerncomputer-macht-auch-erwachsenen-spass-2311-179186.html ) before Christmas and ordered it to play with:

https://picoboy.de/


https://picoboy.de/einfuehrung/das-geraet/
https://picoboy.de/einfuehrung/fuer-erfahrene-nutzer/

Also in the hope that the PicoBoy would work with MMBasic and not just the MicroPython and C++/Arduino mentioned there.
YES it works with the new version for the PicoMiteV5.08.00  

If anyone else in Germany or the EU is interested,
here is the option list:

OPTION SYSTEM SPI GP18,GP19,GP16
OPTION AUTORUN  ON
OPTION COLOURCODE ON
OPTION LCDPANEL SSD1306SPI, LANDSCAPE,GP8,GP9,GP10, 2
OPTION AUDIO GP14,GP15', ON PWM CHANNEL 7
OPTION MODBUFF ENABLE


This will run PicoSpin (https://www.thebackshed.com/forum/ViewTopic.php?FID=16&TID=16611 ) directly, the line "FRAMEBUFFER copy F,N,B" has to be copied out.
And playing a MOD file AxelF in parallel :-) So much for the mini-speaker only being able to play sounds. BUT extremely quietly!
Unfortunately no video with sound, just a picture:



I have not yet tested the accelerometer (also due to time reasons). But it should work via I2C. Has anyone got the STK8BA58 running under MMBasic? I would be happy to receive the correct i2c commands for initialisation and reading!

A fun toy for the pico collection.

I really like the idea of the powersupply via CR2032 battery! I already asked Peter whether it is possible to make use of the two sleep modes the pico has built in, but unfortunatly he says it isn't possible (but others seems to have no problems with it?!)...

So have you any experience how long the pico will last with the CR2032 (maybe with CPU clocked down)

Greetings
Daniel

From the Pico playground github

  Quote  Examples of using low power mode; these use pico_sleep from pico_extras which is not yet stable.


others may choose to use non-stable software but you would just complain if I implemented it and it was unreliable. Please stop with the innuendo

A CR2032 won't last all that long while the RP2040 is running no matter whether it's running MMBasic or anything else. You only make a real power saving in the minimal power mode, but then there are no clocks or oscillators running. It is effectively dead and will only wake up on an interrupt pin. The next level up runs oscillators (and a clock IIRC) so there is a power drain. The system still isn't fully functional though. You would use this mode to temporarily shut the device down to low power between operations, say as a temperature logger.

While the display is running this is all moot anyway. That has to be powered, together with its backlight, as well as the RP2040 or you'll see nothing. IMHO the CR2032 is little more than a gimmick really. It keeps the size down though. :)

It is a gimmick. Too small.

With 3x5cm it is one third of a credit card. When your (my) thumb is on the joystick, the display cannot be seen anymore. Have fun !!!

Nice Project
For controllers where you need a text output, certainly not less interesting
With a resolution of 128 x 64 Pixel on a 1,3“ b/w-OLED-Display, I can't imagine that this can become a competitor to Game*Mite.
