Couple that with the streaming parallel port on the PIC, and it should be possible to transfer data from the AcqRAM to the PC at or near the USB2 Full Speed (12Mbps) transfer rate. Unfortunately it seems the SPP can only run in Isochronous mode. As far as I can tell, you can't just tell it "translate a read of 64 bytes from endpoint 2 into 64 read cycles on the slave port"... > To be honest with you, and this is my own opinion, forget the 'scope > options. I sense that a lot of people like hardware scopes (just like > DMMs) and the same people favour computer-based logic analyzers! (Go > figure). The reason I wanted the scope feature was because I wanted something similar to the old HP/Agilent LogicDart, but with a few more features. I keep finding myself needing to quickly check the voltage on the output of an opamp, while seeing what the PIC's doing with (e.g.) an SMPSU drive FET. If I want to do a quick signal check (e.g. is the PIC running, what's the noise level on the +12V line, etc), I'd rather have a little handheld box that can do simple checks than have to drag the logic analyser and/or the oscilloscope out of the cupboard. You can only do so much with a multimeter. > Regulatory approval is a b*tch everywhere. Can you circumvent CE by > selling a kit or "hobbyist" version? Maybe. I can probably get around most of the US FCC regs by declaring it for laboratory / industrial use only. ISTR that exempts the device from most of the EMC and RFI restrictions. I seriously doubt that you can pull the same trick in Europe. -- Phil. | Kitsune: Acorn RiscPC SA202 64M+6G ViewFinder philpem@dsl.pipex.com | Cheetah: Athlon64 3200+ A8VDeluxeV2 512M+100G http://www.philpem.me.uk/ | Tiger: Toshiba SatPro4600 Celeron700 256M+40G -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
