Fieldnotes from the USB support system built into Annex32 version 1.51.8.
Posted: Fri Dec 29, 2023 9:52 am
I locate in my stash a small wireless keyboard with a built-in touchpad. However, I can't find any USB C male to USB female adapter, so I buy it at a large appliance store.
I put in fresh batteries, turn on the keyboard switch, and plug the USB adapter + wireless dongle set directly into a USB C port on my computer. I check using notepad that both the keyboard and the mouse (touchpad) work perfectly. When connecting it for the first time to the ESP32, we are going to go a little blind and it is essential to be sure that it works.
I solder the IN-OUT and USB-OTG pads indicated by Cicciocb in the new help 1.51.8 on my ESP32-S3.
I connect the ESP32 to a USB port on my computer and on the [Local Link Removed for Guests] page I update to the new version without any problem. Since I have only checked the box corresponding to firmware, it respects the previous configuration and the programs it contained. A round of applause for Francesco.
I assemble the entire system VGA monitor + ESP32-S3 VGA board + USB adapter + wireless keyboard receiver + keyboard with touchpad and turn on the assembly.
I load the little Cicciocb demo program at [Local Link Removed for Guests] and.... Disappointment. I don't get anything.
I comment on the line vga.pinout 4,5,6, 7,15,16, 17, 18, 8.3 which I remember was not necessary for my system and the screen begins to appear, but the execution is interrupted due to lack of fonts files , image, etc. I decide that to start on USB it is too complicated a program and I simplify:
The magic is done! In the log window, the keyboard codes and the mouse position quickly appear as I press keys or slide and tap on the touchpad. Bravo!
I grow up and write a more complicated program:
And the magic continues. The sensation of seeing the characters that I press appear on the VGA screen is curious. Something so everyday, but this time through an ESP32 and Annex.

Note: I can't get the [Enter] key to jump to the next line of the textArea, but everything will work. However, if Francesco gave me a clue...
