Hello
I'm currently developing a Midi controller to control GrandMa on Pc (Lighting control software).
The main part of the controller is the fader wing. It consists of buttons, encoders and motorized faders.
These are controlled through dedicated chips by a RP2040 over i2c. A simplified schematic is attached.
I've already got these PCBs produced and tested them successfully.
At the current stage I'm thinking about how to tie the fader wings and future expansion together (See the second schematic).
The RP2040 could be used standalone as it does supports MIDI over usb, which is the main thing I need.
But I though about using a more powerful and feature rich MCU to increase performance and allow for as much expandability as possible.
The Teensy 4/4.1 could be a good option, but the RT117x seems to be even more promising (1GHz, dual ethernet with TSN, 2D GPU, etc...).
I've read the Future Teensy feature thread, where the RT117x is already mentioned.
This would be great as developing a board incorporating this MCU on my own is not an option.
Furthermore all currently available dev boards do not seem a good option (Coral micro, EA uCOM, Avnet MaaXboard) due to support, availability, footprint or pinout.
Now that I want to start developing the firmware, I could use a currently available Teensy board with the plan to migrate to a next gen Teensy board.
I'm aware that I'm relying on something that does not exist yet, but this is a hobbyist project with an open timeframe, thus I'm willing to give it a shot
Would this be a viable temporary solution? How much effort would it be to migrate from a Teensy 4/4.1 to a RT117x?
And last but not least, can there be anything said regarding a potential Teensy 4.1 successor?
I would appreciate helpful input regarding this.
