monsonite Posted August 23, 2015 Report Share Posted August 23, 2015 Hi All, It's been a few months since I last powered up the Papilio Duo, but today I have it running with ZPUino and the Adafruit GFX graphics library. The aim is to create a simple, stand alone imaging system that can be used to capture images from a Scanning Electron Microscope (SEM) The 800x600 VGA available will be fine for displaying static captured images - but I think I might need to hack the VGA resistor chain, so that I can produce an 8 bit monochrome image, possibly with an 8 bit colour overlay. The scanning system will be a pair of 12 bit DACs allowing an overall 4096x4096 field of view, but the VGA will only offer a small window into this - say 512 x 512. Image storage will be 8 bit monochrome bitmap to the SD-card on the retro-computing shield. Attached is a 720x576 scan of some artificially generated, unsynced test pattern. White field on LHS and below is for tool icons and text captions below As usual I will keep you posted to progress. Ken Quote Link to comment Share on other sites More sharing options...
