| 11:17.41 | wmat | SpeedEvil: that origen board looks very Pandaboard-like. Nice to see lots of low cost dev boards hitting the market though. |
| 11:18.10 | wmat | SpeedEvil: it wasn't that long ago when dev boards were in the many thousands of dollar range |
| 11:19.17 | SpeedEvil | Indeed. |
| 11:19.29 | SpeedEvil | I was more meaning that - rather than 'this board is awesome' |
| 11:19.55 | SpeedEvil | It would be nice if more of them would say 'we don't mind you building a product round this' though |
| 11:20.17 | wmat | the swappable cpu board looks interesting |
| 11:20.26 | SpeedEvil | Missed that bit. |
| 11:20.38 | wmat | and yes, they should all state that anyone can build anything around the board |
| 11:21.08 | wmat | although, in their defense, they don't really see dev boards as production platforms for products when they go out the door |
| 11:21.13 | SpeedEvil | Yeah. |
| 11:21.25 | SpeedEvil | And I suspect that in some other cases, they're subsidised. |

| 15:55.03 | RushPL | SpeedEvil: I'm asking for any part numbers because SRAM is quite erm .. expensive and I want at least 8MB of RAM. Performance of it is not crucial. |
| 15:55.20 | RushPL | RAM > no-RAM :P |
| 15:55.24 | SpeedEvil | If performance is _really_ not crucial. |
| 15:55.28 | SpeedEvil | You can bit-bang it. |
| 15:55.56 | SpeedEvil | It's not actually that bad - if you want to read/write large amounts at once. |
| 15:56.19 | SpeedEvil | As all you need to do is to setup the initial address, set the mode to read, then strobe the clock, reading the data after each clock edge |
| 15:56.42 | SpeedEvil | But for random access, the speed won't be pretty. |
| 15:56.49 | RushPL | SpeedEvil: I really need it for holding some bitmaps and then send it to a TFT controller. |
| 15:56.59 | RushPL | and flash .. is too slow on the other hand |
| 15:57.18 | SpeedEvil | I was looking at something similar - and I realised by happy accident - that I could do something similar to the above. |
| 15:57.25 | RushPL | SpeedEvil: what about SDRAM refresh? |
| 15:57.51 | SpeedEvil | But if I setup the enables right - I could simply clock both the camera and the chip at the same time, and it'd read directly into the RAM from the camera |
| 15:58.07 | SpeedEvil | Enable self-refresh mode, and a couple of other cautions. |
| 15:58.13 | *** join/#edev shodan45 (~chris@mail.duxware.com) |
| 15:58.36 | SpeedEvil | All I needed to do was to do a line from the camera, then setup a new address, and do another line. |
| 15:58.44 | RushPL | SpeedEvil: can you throw me some part number I could look the spec for? |
| 15:58.48 | SpeedEvil | Very little CPU involvement in reading in the whole frame. |
