Hi, my Teensy 3.2 was on a breadboard, connected with Raspberry Pi via its GPIO pins.
Teensy was the only module on the breadboard.
Everything, the sketch and I2C communication between Teensy and RPi worked, but I made a dumb mistake of connecting RPi's 5V pinout to Teensy's 3.3V in (instead of the 3.6-6V vin).
Teensy got really hot, and there was some smoke coming out of the black chip in the middle.
I disconnected everything soon, and let it cool down.
After a while, I made sure I connect 3.3V on RPi to 3.3V on Teensy, and tried I2C communication (Wire class). Teensy still ran the sketch that was uploaded, but Raspberry Pi kept not detecting Teensy.
I tried connecting RPi to another I2C device (OLED module), and it could detect the OLED module well. I also tried moving Teensy to another location on the breadboard.
Bottom line is, I can still upload code onto Teensy using the USB port connected to another computer, Teensy runs the script, but I2C (Teensy side) seems not working..
Has anyone had similar experience? Any advice for what to try?
Thank you in advance!
