Calculators

Post by i_myself_matthew » Wed Nov 12, 2003 10:22 pm

Does anyone know what protocol Texas Instruments graphing calculators use? <p>I am thinking of making a device to send data such as variables from a PIC chip to a graphing calculator and I was wondering what kind of provisions I need to make for such a design.
The PIC would not be doing anything else during transmission, and can be run up to 20MHz.<p>Thank you for your insight.<p>-Matthew
