I have measured the voltage on the pins and foud that some pins are ON.
They are: D14, TX0, RX0, D5, RX2, D15
When I flashed the board with another vertion of micropython (esp32-idf4-20210202-v1.14)
pin RX2 became OFF.
Do I need to swich them off using
Code: Select all
for example, in boot.py, if i need them in LOW state after reboot?
While writing this post, i have been measuring the voltage many times, and I noticed, that mostly i get 0-0.1v on the OFF pins, but sometimes all pins of one side from D27 to VP (d27 d26 d25 d33 d32 d35 d34 VN VP) show about 1v or 0,8v.
