#fabgl — Public Fediverse posts

@bonkers thanks to #FabGL terminal emulation is already working ... 😎 so now I have a nice little embedded development system (there's a PS/2 keyboard connected, but it's not in the photo)

Yay! 🥳

I just made my #TTGO #VGA32 use the #esp32forth variant with #fabgl enabled (a.k.a. #ESP32forthStation ) *and* properly recognize the onboard #sdcard !!

In the end the modification was quite simple, I had to tell the TTGO VGA32 the proper SPI pin configuration for the sd card via SPI.begin() and added that code to the SD.begin word definition.

By default, SD.begin would use the #esp32 default SPI pin configuration which is not being used on the TTGO VGA32 (see TTGO VGA32 pinout).

EDIT: but it took me hours to realize that I used a video resolution which consumed too much memory, causing each attempt to do a "SD.begin" in ESP32forth to fail ... lowering the resolution to 640x200@60 did do the trick! 😎

Time to go to bed ... 🥱

Happy holidays with #retrogaming on an ESP32-SBC-FabGL by @olimex based on the awesome #fabgl by Fabrizio Di Vittorio #vga #vic20 #cpm #dosgaming #pc #emulator

@freedosproject Another way to run #embedded #FreeDOS is to emulate it on #LilyGo #TTGO #VGA32 #ESP32 using #FabGL: https://youtu.be/eM4TYgdEDlo

@dillo Or #LILYGO #FabGL #VGA32 with #Dillo on #FreeDOS?

@tyamadon501 @freedosproject #fabGL can run many OS-es out of the box, including #FreeDOS, MS-DOS, #SvarDOS, CP/M, #GEOS, #Linux ELKS and even #Windows 3.0! https://github.com/fdivitto/FabGL/blob/master/examples/VGA/PCEmulator/mconf.h#L84-L96
