Two new PMOD prototypes are ordered from OSHPark ! 3bit and 12bit color depth HDMI interface. Can't wait to test them on the iCEBreaker! :D

Another day another PMOD! :) Today: 12bit HDMI PMOD module based on @bml_khubbard 's PMOD design. It was much faster as I already did the 3bit version, and I could reuse a lot. ;) https://github.com/icebreaker-fpga/icebreaker-pmod/tree/master/dvi-12bit/v1.0a
A small update today. Corrected pinout to be compatible with blackmesalabs original. And while I was already fixing this I added pinout legend on the silkscreen and a 3D model for the HDMI connector. ;) (you can find it here: https://github.com/icebreaker-fpga/icebreaker-pmod/tree/master/dvi-3bit/v1.0a )
Initial commit of 3bit HDMI PMOD module based/inspired by Blackmesalabs PMOD. Changes:
* KiCAD aka. there is a schematic for it :D
* 4 Layer PCB
* More decoupling capacitors
* Bit larger than the original

These P2 panels are really nice! 64x64 LEDs per 128mm tile! You can get some nice effects by shorting the enable pin to ground and “stroking” the ribbon cable :D Can’t wait to get them connected to the iCEBreaker!
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
Added PDM (Pulse Density Modulation) with gamma correction look up table to the iCEBreaker examples. Lesson?: Unless I am missing something obvious, as soon as you need more than one PDM generator the savings compared to a PWM generator start to diminish. https://github.com/icebreaker-fpga/icebreaker-examples/blob/master/pdm_fade_gamma/gamma_pdm.v
One more example added to the iCEBreaker repository. PDM (Pulse Density Modulation) LED fader. Lesson learned: you don't have to stick to the solutions you know from the MCU world you can go beyond! Thanks @iamtommythorn for sharing! https://github.com/icebreaker-fpga/icebreaker-examples/tree/master/pdm_fade
Another example added to the iCEBreaker repository. PWM LED fader with gamma correction. FPGA are made for this!!! :D The demo uses a typical 2.2 gamma, but can be easily changed in the lookup table generator. https://github.com/icebreaker-fpga/icebreaker-examples/tree/master/pwm_fade_gamma
Adding more examples to the iCEBreaker repository. PWM generator to fade LEDs anyone? :) https://github.com/icebreaker-fpga/icebreaker-examples
