Astralixi Lyra OS Megathread

PicoCalc

I recieved my Pico 2W board, switching my Pico 1 board with the Pico 2W, was a little bit of a nightmare, but I got it without breaking anything :slight_smile:

New Devlog Coming Out On Saturday

It will basically be me unboxing my Pico 2W, and then yapping about the build error iā€™m getting for around 30 secondsā€¦

Is there anything for Pico graphics in the Pico SDK?

232

The only aspect of the Pico that intrinsically has anything to do with graphics is HSTX on the RP2350, which is designed with DVI in mind but leaves the implementation details up to the user. Aside from that, the RP2040 and RP2350 can both be used with numerous different SPI and I2C displays. Consequently, the Pico SDK exposes interfaces for SPI and I2C but is display-agnostic.

233

@BlairLeduc Does you picocalc-text-starter have anything which does graphics at 1 bit level (monochrome)?

234

Astralixi OS API has been updated for Pika Python, instead of being a C header file!

235

No, it doesnā€™t. It is a starter library to get you going with the standard C library using printf and fwrite. The standard C library does not have graphic functions.

Though it would be awesome if someone ported SDL to the PicoCalc!

I could try make an SDL-like graphics thing for the PicoCalc.

237

You definitely could, though it would not be an easy path.

238

What if I try an merge a SDL like graphics thing with pkklib?

239

That is still not an easy path.

240

focus, get a basic text only screen working first before you add a whole graphics layer

I hoped for Vulkan support but SDL is great too! :grin:

Joke aside, maybe should take a look on SFML, they have an android port.
A lot of work indeedā€¦

NEW DEVLOG JUST RELEASED!!!

244

Different Codes for the OS:

  1. Main Source Code (only I will be able to access it)
  2. API code (everyone can access it)
  3. Preinstalled apps code (verified app developers will gain access to it)

Does this seem fair?

Here is the error message seen in this devlog:

Update: The issue is to do with the arm-none-eabi-gcc thing and Iā€™m trying to figure out whatā€™s wrong with it
