Using GPIO15 as GPIO OUTPUT in ESP32-WROOM
Posted: Tue Sep 17, 2024 1:10 pm
Hello,
I have to use the GPIO15 of the ESP32-WROOM as output because it is connected with the enable signal of other component in a custom board.
I have it configured like this:
The GPIO14, GPIO02 and others with I have made some tests work properly. But when I put the level of GPIO15 to high, I get the following signal:
I have tried to use the "gpio_reset_pin" function in order to reset the GPIO15 because I have read that is a strapping and JTAG GPIO, but it doesn't work.
How could I use it as normal output?
Thanks in advance
