The WTFpga #hackaday #supercon workshop was a great success! Thank you everyone who attended! If you were there I hope you had fun! :D The complete code and updated booklet are available on github. https://github.com/esden/wtfpga The only thing missing is the availability of the iCEBreaker and PMODs. I am working on that now and the crowd funding campaign will hopefully launch soon! :D https://www.crowdsupply.com/1bitsquared/icebreaker-fpga
The Crowd Supply Pre-Launch page for iCEBreaker FPGA development board is finally live! If you want to be notified when the campaign launches make sure to add yourself on the page. Or just follow me mere and I will tell you. I am very excited that we are one more step closer. ;-) https://www.crowdsupply.com/1bitsquared/icebreaker-fpga
Assembled the new RGBI DVI Pmod! It works! Using the hdmi_text 1080p design by @tnt Looks really nice and crisp! It is pretty amazing what the small ice40up5k on the iCEBreaker can do. :D https://github.com/smunaut/ice40-playground/tree/master/projects/hdmi_text
After figuring out from the Chinese datasheet that the part requires an init sequence I found a very helpful thread on @HennerZeller rpi rgb led matrix repository. You should read it if you want to know the details: https://github.com/hzeller/rpi-rgb-led-matrix/issues/746#issuecomment-453860510 Attached are the init signal traces.
Here is an improved schematic. Fixing some signal names. Thanks to the sharp eye of @vogelchr :D
I am sure you were burning with the desire to know how the drive circuit of an RGB LED Matrix panel looks like. Me too! I have started a repository to collect drive chipset schematics and datasheets. https://github.com/esden/led-panel-docs
New prototype of iCEBreaker single Pmod DVI with 4bpp. Extended 16 color palette, using only one Pmod connection. Ordered from OSHPark (Thanks @tnt for the suggestion!)
@vifino And as I threatened yesterday I did indeed create my first effect for sled. A classic fire! :D
To celebrate Sunday I got @vifino sled (Satanic LED controller) running on my iCEBreaker driven LED panel! It is a nicely modular and flexible tool. The effects are great! Thanks to everyone who contributed! Now I want to make some of my own! :D github.com/shinyblink/sled
Success! If you want to make your own SPI flash programming fixture for the TOMU FOMU v0.0 FPGA board: https://github.com/osresearch/fomu-hardware/blob/master/hacker/fomu-jig.svg
