Greetings While Brendan and Jaya have been furiously writing emails I have been working on my LPC2148 ADC code. Its taken me a while but I now have it clocking out the ADC at a rate of 520 K samples per second. I am over clocking the ADC a little at 5 Mhz but my noise is well within my required spec. I didn't think it was possible as I always hit about 320 K or so at best. My 512 pixel camera is now doing over 500 frame captures per second :) The caputured frames are dispatch to the PC via the USB HID example. I have not got the HID example to run very stable yet (has anyone ?). I can send packets (64 byters) to the PC no problem at a fair rate (5ms). Just when I send packets from the PC to the 2148 I intermittently get a permanent code slow down and the USB stops communication (but stays connected). If anyone knows the solution to this I would be happy to hear it. My Setup is: Keil 3.31 using the ADS realview that came with it. ARM mode with no optimising. Keil MCB2140 dev board with a ULINK. Cheers Keith
