Re: 5x7 dot matrix screen

The Dot Matrix program now has a presence on github:

https://github.com/edriveX16/DOTMATRIX

Most of the source code is still missing, but will be added later.


To clarify licensing issues, I have placed the program under the MIT license.

Max. Voltage off PICO pwr adapter?

What is the max. input voltage of the PICO ATX power adapter? On the texelec site it states: "Input Voltage Range:11.4VDC—12.6VDC" But would it get fried, from a simple wallplug type rated at 12V (from the type of transformer, bridge rectifier, capacitor), with a no-load voltage of say 15V...

Re: create a new sdcard.img

Keine Ahnung wie und womit die Ersteller des ursprünglichen Image das gemacht haben. Dazu müsstest du die Autoren selbst fragen (oder es findet sich was in der Doku). Prinzipiell sind aber folgende Szenarien denkbar: Das Projekt wurde mit echter Hardware und echter SD-Karte gemacht. Oder es wurde mi...

Re: create a new sdcard.img

The x16emu has a command line option to specify a sdcard image at startup. https://github.com/rsbohn/x16-emulator/blob/master/README.md -sdcard lets you specify an SD card image (partition table + FAT32). (but the examples from your link somehow didn't work...

Re: float asm...read the value with peek?

We are on par. After I was half through the lessons, that "Dot Matrix" program idea came to my mind.

Still need to learn many things...
