No promises I'll have stuff for the GTG in time but I've got a Raspberry Pi 3B+ working with an SPI based encoder -- the lack of an encoder interface that counts pulses in hardware was what was keeping me off the Pi. The Beaglebone Black seems to have gone off into the sunset last couple years. The Pi has built in WiFi radio which removes a LOT of the pain of the dongle based one used on the black. The load cell will plug right in and work like it always did. The RPM/Torque/HP display will work on the same SPI bus as the encoder module and I'd like to keep those since they are so easy to watch in the sunlight and they do give you that satisfying instant feedback when running a saw.
I have some things I want to change to the software to support gathering all data at very high speeds and storing it raw (all of it instead of what was post process during data gathering) so things can be applied to the data after the fact such as tuning a digital filter to get decent hopefully much more usable graphs even with the vibrations we had from the brake disc etc.
For those who have no idea what this is about -- the electronics for generating RPM / HP / Torque graphs for a chainsaw dynamometer.
Messed with it a bit here and a bit there and getting close to putting this in the original box or perhaps a new box and see what we get...
