GPIO 6 to GPIO 11 are exposed in some ESP32 development boards. However, these pins are connected to the integrated SPI flash on the ESP-WROOM-32 chip and are not recommended for other uses. So, don’t use these pins in your projects: GPIO 6 (SCK/CLK) GPIO 7 (SDO/SD0) GPIO 8 ...
I use GPIOS: 2 - Output 4 - No output 5 - No output 8 - Output 9 - Output 18 - No output 37 - Output (I have some others that I plan to use, but they tie directly into motor drivers etc, and as I'm still testing I haven't gotten that far yet.) The above GPIO are ...
Thanks but I still want to use GPIO to wake up DeepSleep. I noticed that External Wakeup can be used to wake DeepSleep with RTC GPIO, but I didn't find any description on the web about which pin of the ESP32 C6 can be multiplexed as RTC GPIO. ...
Pin configuration and the number of pins.To properly use the ESP32 in your projects, you need to have access to the board pinout (like a map that shows which pin corresponds to which GPIO and its features). So make sure you have access to the pinout of the board you’re getting. Oth...
There is no connection at all between the GPIO module and the DMA subsystem; the AI's are happily confabulating a connection here. Dependent on what you want and what specific chip you use, you may want to look into the RMT, the I2S (in parallel mode) or the LCD/camera module as ...

ready to send/receive data, this code uses a callback to set the handshake pin high. The sender will detect this and start sending a transaction. As soon as the transaction is done, the line gets set low again. */ /* Pins in use. The SPI Master can use the GPIO mux, so feel fr...

ESP32 comes with 10 GPIO touch sensor pins which sense the variation in electrical charge upon touching. We can use this feature in designing touch sensitive projects which can replace normal push buttons. Here we covered taking input and controlling LED using the touch sensor pin....
