Teensy4.1 <-> Platformio?

[Pito Salas]

Are we sure that the platforio on the linorobot.org install kit will properly compile code for Teensy4.x? Because the directories, the make file and so on all say Teensy 3.x and that is worrysome. 

Can someone confirm this? Thanks

I just pushed some changes for Teensy4.1 compatiblity here: https://github.com/linorobot/linorobot/commit/ce17dc24be44e9a2ea30386773540df77b8b04db

 

Take note that you'll now need to specify the board that you're using. Pull the most recent firmware and run:

cd linorobot/teensy/firmware

pio run --target upload -e teensy41

Success! These changes and switching to the 4.1 environment seems to have fixed the problem. Thanks!

Hi again

I have several linorobts, with teensy 4.1 and teensy 3.6. Is the linorobot/teensy source tree the same in each case? In other words, if I put it into GitHub and use the same one on the two robots, given that they are recomiled with the -e teens41 or -e teensy36? Or are they different and I need two different github repos?

Thanks for your efforts.

Hi Pito,

You don’t have to. The only difference is the definition of which Teensy board to use which is already done automatically by Platformio when u use the -e tag.

Hi Juan

Good chatting with you today.

This is the I2C interface:
https://github.com/simplefoc/Arduino-FOC-drivers/tree/master/src/comms/i2c

Which should support our small driver:
https://github.com/rosmo-robot/Rosmo_ESC#readme

Or the larger one
https://github.com/Twisted-Fields/rp2040-motor-controller#rp2040-motor-controller

I'll let you know if I have any success with the grant.

Thanks

Sam
