#142484 - Not for the weak in heart Responding to: ???'s previous message |
Thanks Jan.
I read the other thread which was referred to and saw your summary on this MCU-driven-VGA stuff : However, a plain 8051 without any external "help" is not capable of the pixel rate the VGA requires. Note that the horizontal frequencies are in the range of 30kHz and higher, so to produce something like 200 "dots" horizontally (which is most probably not enough for what you want) you are in the range of >6MHz (there is some time neeed for the retrace/sync, so count up +20% for it), well beyond anything a '51 (even the faster derivatives) can produce as an output... Well this "is" the kind of info that I was looking for. No Googling will tell you this. I have already started looking for non MCU solutions for my requirement. Regards Raghu |

| 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 |
