I would try a pic16f1827 it has internal SPI and can be used to drive the display in 8 bit mode... That takes out the errant ones that don't like the 4 bit mode I have found a few examples. there is an internal clock and it will run up to 32Mhz so its quick enough to manage a 2 or 3 wire SPI a keyboard and a display in 5(6) cables... (with a CS line) also no reason it couldn't drive a T6963 based graphic display either it just needs an extra line to the display (it has /Rd and /WR) Steve On 29 April 2014 14:01, Larry Bradley wrote: > Many thanks to all who responded with thoughts and ideas. > > If I were producing something, I would certainly choose the appropriate > chip(s) for the job.
