| 8051 to VGA | | 01/01/70 00:00 |
| nope..... but i do know | | 01/01/70 00:00 |
| Video | | 01/01/70 00:00 |
| well, if throiughput is a problem | | 01/01/70 00:00 |
| VGA vs. NTSC (OK, PAL) | | 01/01/70 00:00 |
| especially on CRTs? | | 01/01/70 00:00 |
| flicker | | 01/01/70 00:00 |
| Distortion | | 01/01/70 00:00 |
| until today... | | 01/01/70 00:00 |
| Logical Processors | | 01/01/70 00:00 |
| not likely ... | | 01/01/70 00:00 |
| sure, but what problem is that | | 01/01/70 00:00 |
| It's the demand for precise timing | | 01/01/70 00:00 |
| Monochrome? | | 01/01/70 00:00 |
| He may be a bit misguided | | 01/01/70 00:00 |
| Ive used an spi interface | | 01/01/70 00:00 |
| This is the arbitary display overlay jobby | | 01/01/70 00:00 |
| A NICE VIDEO GENERATING AND PROCESSING EXAMPLE!! | | 01/01/70 00:00 |
| Is it VGA? | | 01/01/70 00:00 |
| Video Buffer | | 01/01/70 00:00 |
| and a "video DAC" | | 01/01/70 00:00 |
| Well there are ways and ways .... | | 01/01/70 00:00 |
| but VGA is twice as fast | | 01/01/70 00:00 |
| VGA Pixel rate is faster but ... | | 01/01/70 00:00 |
| If the MCU can\'t do it all ... | | 01/01/70 00:00 |
| how about this one | | 01/01/70 00:00 |
| "stuffer" | | 01/01/70 00:00 |
| it'd better be a really cheap MCU | | 01/01/70 00:00 |
| why? | | 01/01/70 00:00 |
| the guy who pays for it would notice. | | 01/01/70 00:00 |
| why? | | 01/01/70 00:00 |
| The extra MCU contributes nothing. Why use it? | | 01/01/70 00:00 |
| because | | 01/01/70 00:00 |
| TEXT => Pixels = character generator | | 01/01/70 00:00 |
| sure, but | | 01/01/70 00:00 |
| True, but only sometimes ... | | 01/01/70 00:00 |
| HUH? | | 01/01/70 00:00 |
| so ... which MCU has those built in? | | 01/01/70 00:00 |
| those? | | 01/01/70 00:00 |
| Here's what "those" are ... | | 01/01/70 00:00 |
| options | | 01/01/70 00:00 |
| working examples | | 01/01/70 00:00 |
| Nice to think folks remember Don's "cheap video".. | | 01/01/70 00:00 |
| What do you mean, Phillip? | | 01/01/70 00:00 |
| A notion not to radical or heretical ... | | 01/01/70 00:00 |
| I still think it's either/or and not both | | 01/01/70 00:00 |
| Like the vhdl that you'll find | | 01/01/70 00:00 |
| Here's an ARM7 Driving a VGA Display direct | | 01/01/70 00:00 |
| 75 Ohm? | | 01/01/70 00:00 |
| 75 Ohm it is... | | 01/01/70 00:00 |
| dc motor | | 01/01/70 00:00 |
start a new thead - and be specific | | 01/01/70 00:00 |
