#142632 - it's not mine... Responding to: ???'s previous message |
Stefan,
that board is not mine, I mean, the board itself is, I bought the prototype which is on the pictures there; but the idea and design is of that guy (J.Bezstarosti). I think it could be converted to VGA relatively easily, although it would probably require a proper videoDAC (and more memory of course). Hovewer, a standard '51 has barely the horsepower to feed even the TV version - I am using 8-bit color at the moment, and a stupid clearscreen takes around half a second with a 12-clocker @ 22.1184MHz (all asm of course). This is an often overseen problem - graphics generation is computationally very expensive, and even some of the simplest operations results in huge amounts of data manipulation - and this of course takes time.

| yeah,well no not really | 01/01/70 00:00 | |
| buy a module | 01/01/70 00:00 | |
| this depends... | 01/01/70 00:00 | |

| Good reference thread.. | 01/01/70 00:00 | |
| an interesting project | 01/01/70 00:00 | |
| Not some but complete !! | 01/01/70 00:00 | |
| seems to be ARM based | 01/01/70 00:00 | |
| ah yes! | 01/01/70 00:00 | |
| thank You for dsPIC | 01/01/70 00:00 | |
| Stefan, are you kidding? | 01/01/70 00:00 | |
| Your TV board is nice | 01/01/70 00:00 | |
| it's not mine... | 01/01/70 00:00 | |
| so what You think - FPGA or not | 01/01/70 00:00 | |
| IMHO not | 01/01/70 00:00 | |
| now they have vga640 x480, 256 colol | 01/01/70 00:00 | |
| no need for external SRAM interface | 01/01/70 00:00 | |
sorry, just searching for opinions | 01/01/70 00:00 | |
| That was what I needed ... | 01/01/70 00:00 | |
| are there no modern alphanumeric terminals? | 01/01/70 00:00 |
