    random phase difference between signals on ICE40

    The input signals (5 of them) come out of the retro machine. I send them though an NVT2006PW voltage level translator to pull them into the ICE40 fpga. The chip they come out of in the old computer is a proprietary one, so I was lucky already to find the pinout I guess. Unfortunately I have no...

    random phase difference between signals on ICE40

    That is what I thought. One option I could try is to use the original data to recreate sync instead of creating sync from scratch. Or at least use that original signal to start the counter. That would solve the problem probably although it frustrates me not knowing what is causing the current...

    random phase difference between signals on ICE40

    Hi! I'm a starter using FPGA's and was hoping somebody here could point me in the right direction... To code my iceFUN ice40 HX8K I use icestudio. I am pulling a 5 bit wide signal into my iceFUN board. This signal contains pixel data from a retro computer. The machine also makes sync with...
