Hello everyone,
I'm having an issue with the Teensy LC.
I've connected an I2C accelerometer (MPU6050) and using teensy as a midi controller.
For debugging, I just compile in standard mode (usb serial) and it works great.
However I am trying to connect a RGB "analog" led strip (with R,G,B and 12V wires) with TIP120 transistors as described here : https://www.jerome-bernard.com/blog/2013/01/12/rgb-led-strip-controlled-by-an-arduino/
It seems to work but as soon as I connect the external power supply ground to Teensy ground, serial communication breaks.
As soon as I disconnect grounds connection, it works again.
Is there a way I can make usb serial work using the external power supply ?
Thanks a lot !
