Thanks for your replypygmy_giant wrote:Cool ... seems like its aimed at quadcopter type applications ... what sort of things do you imagine it being used for? Is it an expansion board or would it require the Pi to program and then run autonamously afterwards? Would replacing the 1K EEPROM with a 512K EEPROM cost much more or cause problems?
Hi. The reason was cost, I got a better price from Xilinx on the XC3S200A than the XC6SLX9. Well... it was when I started... they later came back with a closer price (still more expensive) but I was too far down to change so I stuck with the S3. I'd agree with you that the S6 is a better choice but 'cheaper' won the battle for now... The S6 is available in the same package so apart from some re-routing it shouldn't be too much effort to change it at a later date. Right now I'm fighting to keep the cost down so every peny saved give me a chance to put this into production.bswiec wrote:Hey Mark,
Out of curiosity, is there a reason you went with the older Spartan 3 device instead of, say, xc6slx9 for a similar price point? Has more resources/performance (including DSP slices and hard memory controller).
I haven't... But then I have years & years worth of experience with Xilinx & Altera FPGAs and haven't even heard of the IvanSense part or AK8975 so I went with what I know best. You can do anything with a Xilinx anyway...pygmy_giant wrote:Also have you considered using the IvanSense MPU-6050 and AK8975 ?
Very nice! I'm glad to see you're making progress.MrMarkus wrote:The PiXi-200 project is moving forward. I recently took delivery of a sample of the bare PCBs so I took the opportunity to pop a few connectors on one of them and take some pictures to help illustrate what it'll look like and how it connects to the Pi.
Thumbs Up! will keep update on your progress.. looking forward to buy one of these!MrMarkus wrote:Latest update...
Woohoo! - Christmas came early and the boards arrived early yesterday as hoped. So far it looks good. The Pi can program the FPGA, the lights flash, switches work... basic stuff but it'll be a little while before I've tested everything.
Anyway, I'll update the pictures on the website next and get on with testing the rest of the board - in between finishing off the Christmas shopping of course...
All for now, next update will probably be after Christmas, so have a Merry Christmas all!
That's the plan, we've had interest in the PiXi-200 from all around the world so we'd very much like to be able to support that interest and ship world-wide.Just "discovered" your board and I want the new one! Do you ship across the pond?
