Arduino core for the ESP32Project mention: USB is not building | reddit.com/r/esp32 | 2022-11-26
So I came back to the Arduino error and started digging into the library itself. And, well, I mean there really is no soc/usb_reg.h in the library even though that same library points to that file (and others that aren't there either). The error points me to this file arduino-esp32/usb_periph.h at master · espressif/arduino-esp32 (github.com) . Which goes looking for soc/usb_reg.h (and others) which WOULD be here arduino-esp32/tools/sdk/esp32/include/soc/esp32/include/soc at master · espressif/arduino-esp32 (github.com) except it isn't.
U8glib library for monochrome displays, version 2Project mention: STM32F411RE and SH1106 OLED Display | reddit.com/r/stm32f4 | 2022-10-21
For displays like this, I strongly recommend the U8G2 (https://github.com/olikraus/u8g2) library. It has support for pretty much everything. However, you might need to find/write/tweak your own "hal" later, which is just a couple of simple callback functions that bridge it to the I2C or SPI ports of your MCU.

The Uncanny Eyes are, of course, from Bodmer's TFT_eSPI library, which has also recently been updated for S3 support. You all probly know this library very well, but here's a link to that as well: https://github.com/Bodmer/TFT_eSPI

The feeling of creating your own accessories is awesome! Though, I have been using Arduino-HomeKit-ESP8266, cause an ESP32 feels like overkill.

A simple E-Paper display library with common base class and separate IO class for Arduino.Project mention: MH-ET ePaper module 2.9" help | reddit.com/r/esp32 | 2022-10-16
Hi thanks for your reply. The thing is that i couldn't seem to find demo code on the website though i did find a GitHub repo by MH-ET Live. Going through to the ESP32 file bring me hereto the GxEPD zip file. I've downloaded, included the library in my Arduino IDE and tried running the example code, commenting out all the 2.9" variants but still no luck, the programme freezes at the init stage with no change to the epaper display.

Arduino Display Library for SPI E-Paper DisplaysProject mention: MH-ET ePaper module 2.9" help | reddit.com/r/esp32 | 2022-10-16
From what i understand, by uncommenting display class and display driver class in the GxEPD2_display_selection_new_style.h file, the display class object is constructed in line 144 for esp32, as that file is included in the GxEPD2_Example.ino file.

It's all local. I'm using ESPUI which hosts everything on the ESP.

The solution was an alternative library (https://github.com/lexus2k/ssd1306) which I found through here. It just needed wired to the default pins. Got a lot more to do with the black pill, group project for a prototype ECG

Quite a few firmwares available (RetroESP32 is my personal favorite) that improved performance and added new emulators over the original OS.
