Arduino ZX-ish VGA

Post by ajcasado »

Hi, I'm developing an arduino library to output ZX Spectrum graphics to VGA.
With an atemega1284p board overclocked full ZX Spectrum resolution can be achieved.

Check it out at https://github.com/ajcasado/ardvga

Excellent work but unless you've got dot crawl, it doesn't count :D

The dot crawl can be achieved with this https://hackaday.com/2015/02/26/attiny8 ... -air-ntsc/ :shock: :D

HI!,
I have updated the github repository.
For now it works on the atmega328p mcu boards.
The example prueba runs.
The schematic for nano on breadboard is ok, the schematic for uno is not tested but i guess is ok.
There are a couple of links to example videos.

Hi, I have updated the github repository with a new 1284p branch. It can do ZX Spectrum graphics in a VGA monitor with an atmega1284p clocked at 27MHz.
