Finally got the panels somewhat round. Also got rid of the FPGA dev board and designed my own. The power supply solution has been revised. While the electrical interface specification of HDMI is close enough to LVDS so that the IOBUFs of the FPGA can directly interface to it, there is no propper on-chip termination […]
Got the bigger panels to work. Unfortunately they are much stiffer than anticipated. Expected capton foil, got 0.5mm fiberglass (FR4). Well, we’ll need more force then. Also the HDMI sink now works. I’m genuinely surprised how easy HDMI is. Made my own EDID, the FPGA registers as an ordinary HDMI screen and is driven by […]
Just got all of my LED panel control scheme implemented and everything is working together nicely. Right now I am at 14+8 bit per subpixel (14 bit for each pixel and color + 8 bit for overall brightness). I am using line scrambling to increase the percieved steadyness of the image when the display is […]
