davedarko / gbprinter Goto Github PK

Hi davedarko,

I've forked your repo on octavifs/GBPrinter and added support to transfer images from the PC to the printer.

I've created a go client that converts an image (png, jpg or gif) to the binary format of the printer and then sends it through serial port. The arduino takes that input and sends it using the printer protocol (as you and Furrtek wrote). The sketch and library were also heavily rewritten. It is now a state machine that can keep receiving and printing tasks indefinitely.

Although some parts need a bit of extra work, such as error handling and finetuning the dither algorithm to improve the printing results, the project is very much usable. There are videos and results linked on the fork README.

I thought you might find this interesting, so I'm raising this "issue". I'd be glad to discuss the changes I've done on my fork anytime.

Happy hacking!

your site doesnt work anymore, it just writes ads here :(

I tried replacing the:
uint8_t row0[640]; uint8_t row1[640]; uint8_t row2[640]; uint8_t row3[640]; uint8_t row4[640]; uint8_t row5[640]; uint8_t row6[640]; uint8_t row7[640];

With the hex values used on your site (which also is broken and cannot generate picture, mind OpenSourcing it?) and still no avail.
