My next version was a PIC32MX and ran at 1Mega samples / second.
hi Nigel,
i'm quite interested in this. for the past few days i've been mulling over ways to use a pic32MX170 as a low-end DSO, and this evening started looking into the Cypress device used in the saleae clones. my plans with the MX170 were to use the internal RAM to hold around 50kpts of samples, and send them back to the host over a serial-to-usb bridge.
how adaptable would your pic32 software be for use on a pic32MX270 - with the ADX MUX controlled from the host PC? this would have potential for a single-chip (in DIP package) solution, connected via USB, with switchable input scaling via the MUX using little more than a few resistors in a chain.
cheers,
rob :-)
