I have discovered an unusual situation with my project which I think points to some kind of a bug, but I'm not sure what exactly. I have a project which grabs raw grey-scale 8-bit data using https://github.com/espressif/esp32-camera, slightly modified to run on my particular hardware. The project wo...

Terrific. Thank you everyone! Paul, thank you for posting the code snippet -- I was able to drop that into my ESP32/Arduino code and use it right away, making the ESP32 act as a serial loopback for the FTDI USB/serial interface that is connected to it, and then extending that further to be a cross-p...

In the TRM's section on peripheral output via the GPIO matrix, there are some details that seem to suggest that signals can be steered from one GPIO pin to another GPIO pin. I've used such a technique with Cypress PSoC's and would love to be able to do it with the ESP32! The GPIO Matrix table shows ...

Sorry for replying to my own post, but it turns out (with help from a comment from Reddit) that the initial pin state is described in the ESP32 datasheet, nearly at the end of the document in the Appendix, in the A.4. IO_MUX table. At reset, output drivers are turned off, BUT a number of pins have w...

I have an NodeMCU-32S using a ESP32 WROOM module which I am interfacing to a Displaytech INT024BTFT LCD module. The LCD module has a LCD controller (timing+"graphics engine") and an Atmega (which pre-configures the device at power up) that connects to the host via a parallel bus and some control lin...
