Quote from: fano on 16:10, 29 April 18I'm amazed with color PCW , does it relies on dithering recognition ? (00 and 11 are colors 0 & 1 but 01 and 10 are colors 2 & 3 or something like this)
Quote from: Habi on 01:15, 30 April 18Hi.It's something like that; in 4 colour mode (360 x 256) the index colour is simply each 2 bits group (00, 01, 10, 11 are 0, 1, 2, 3 respectively). Same for 16 colour mode (180 x 256).In attribute mode (360 x 256), reads 16 bits; 8 for attribute (4 background, 4 foreground) and 8 for bitmap. It's similar to Spectrum / Timex, MSX, Thomson, etc. where you have only 2 colours in each 8x1 block, but could use all 16 colours at the same time without rasters at the same resolution as the 4-colour mode. It also facilitates ports from those platforms.
Quote from: fano on 12:47, 30 April 18Nice ! i love the simplicity (not in conception i suppose) and power of the 4 colors mode, do you plan to distribute this card ? does it will need modifcation of the PCW ? do you estimate the cost of the modification ?
Quote from: Habi on 13:21, 30 April 18It's just a prototype at this moment; I'm using a cheap FPGA board (about $10, link) and using about 1% of it.I don't think I'll publish a finished version in the near future because I want to make a bus interface, integrate DK'Sound, HDMI, ... But if you want to experiment by yourself I can send you the code, instructions, etc.
