Hi all, I just finished an emulator for the Hewlett Packard HP-97 programmable desktop calculator (teenix.org) and was thinking of having a go at building one just for a hobby project. The calculator is programmable from a magnetic card and also has a thermal printer. I have the "cards" working from an I2C serial EEPROM, but nothing for the printer yet. Arduino has a library for the Adafruit thermal printer. Does anyone know of a PIC interface? cheers Tony --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
