Re: ESP32S3 GPIO36配置成Dedicated 写入值后没有输出信号 PostbyESP_morris»Fri Oct 14, 2022 10:19 am 看这个write函数的第二个参数:mask – [in] Mask of the GPIOs to be written in the given bundle, 指的是你要操作的gpio在这个bundle中的位置,不是实际的gpio号了。你应该试试传0x01 ...

Interesting fact: the longer the wire on the external button is (lets say about 10 to 20m connected), the more the EN line will be dropped to GND, sometimes completely so that the whole ESP performs a reboot ... Thanks for sharing your ideas!
Every time I read the state of GPIO39, GPIO36, GPIO34, GPIO35 on the first Core of ESP32 and I draw a picture to LCD via SPI on the second core of ESP32 the value of GPIO39, GPIO36, GPIO34, GPIO35 is corrupted. ( this time nobody sends a signal to this GPIO !!! ) ...
There is some hardware problem with GPIO36,39(SENSOR_V*) on ESP32-WROVER-E and cant be used as inputs I checked the schematic of this module (v1.4 Datasheet), don’t see any capacitors attached to those pins (as they were to blame in some other topics for the same problem, but ...
