When the interrupt is triggered, the leve...

Discrepancy between WROOM-32 and ESP Hardware design guidelines

Hi, There is a difference in the two reference sheets "Hardware design guidelines" and "ESP32-WROOM-32 datasheet". Both can be found here: https://www.espressif.com/sites/default/files/documentation/esp32-wroom-32_datasheet_en.pdf https://www.espressif.com/sites/default/files/documentation/esp32_har...

Re: zlib on esp32

UPDATE: This code actually works. Somehow I corrupted my board. I tried the same code on a different board and it worked. Let me know if you run into any trouble.
