Turning Rotary Encoder Seems to Glitch ESP32 #16

Closed rdpowers closed 7 years ago

rdpowers commented 7 years ago

Power LED blinks out, indicating temporary short to ground. Does not occur with button press.

Datasheet seems to show 10k resistors on lines leading to uC I/O. Might be needed, but not sure if this will alleviate the problem.

Proto 3 has bodged in 10k resistors inline with I/O. This seems to fix the earlier issues of browning out the 3v3 line. Should also add small cap. on those two lines, also as shown in datasheet, for debounce.
