Today I messed around with the "f88 and got the code working to push updates to the three multiplexed displays in parallel. The controller, once completed, will be fitted to my dummy load. One A2D will read the voltage on the 1R shunt giving me current, the other will measure the input voltage. During the update process, the pic multiplies these two and gives a third readout in watts. These three figures are then pushed out to three shift registered with linked clocks and latches. Three four digit displays with just 5 IO.
