I have been running a custom built midi solution for the last five years. The solution involves two Teensy 3.2s and an LC. The Teensy 3.2s operate as an midi keyboard interface and sequencer respectively, and the LC as a 'Hammond' drawbar controller, 0.96 status screen, etc. Both Teensy 3.2s are equipped with PJRC SD adaptor cards and Wiznet WIZ850io/WIZ820io (forget which one!) ethernet modules that is integrated via MQTT to a Raspberry PI 3B+ that operates a 10" LCD touch screen enabling real time control of the solution. I am looking at upgrading to Teensy 4.x's and a newer Raspberry PI (less important).
Teensy 4.1 would be a gerat replacement considering that it supports both an SD card and ethernet. However, I would have to rebuild the solution. I noticed there is a comment on the PJRC site that the Teensy 3.2 and 4.0 pinouts are 'mostly' compatible. Minor pin incompatibilities can be handled. My question is two fold: Can I drop a Teensy 4.0 in place of a 3.2, and more specifically, would it be pin and functionally compatible with SD adaptor and Wiznet WIZ850io.WIZ820io ethernet module?
If the SD Card/Ethernet option is not compatible with the Teensy 4.0, then I will move on to the Teennsy 4.1 - a lot more work, but doable.
Thank you,
Anton
