esp32 Cam implementation #182

Open kleffa opened 1 month ago

kleffa commented 1 month ago

anyone have pinout to conect SD to boards or it can be setup by thae code? Im trying to flah it to a esp32cam, wich comes with a SD card slot, but not sure if pins are already

probonopd commented 1 month ago

Good idea to use the esp32cam due to its built-in SD slot. I don't think I have tried using it so far.

Probably you would have to adjust

to match the esp32cam.

it should be
SPI.begin(14, 12, 13, 15); // esp32cam built in microSD{ what I'm doing wrong? by now SD is not working... what happend with GPIO 4 and GPIO 2? those should

by now werbserver and octoprint plugin work, some comunication to printer... but doesnt show ip on screen and webserver didnt show printers name (any idea?) I tried the last relase of a wemos D1, it show ip and SPIFFS, some kind of work, but when send print from pc, it just say terminated, so I´m not sure if has point???

here some changes I had made to work serial

in ESP8266Wiresprint...ino I make this

define LED_BUILTIN 33

HardwareSerial PrinterSerial(0); //esp32 cam only have this PrinterSerial.begin(serialBauds[serialBaudIndex], SERIAL_8N1, 3 ,1 ); // gpio3 = rx, gpio1 = tx

werbserver works and get response from printer, EX Free heap: 197268

File system: SPIFFS Filename length limit: 11 Uploaded file: cached.gco Uploaded file size: 272477

Last command sent: M115 Last received response: 0x400805f0"ok

also set definitions for this things to exchange for TTgoT1 or simple make changes for other esp32 models

Actually now I vaguely remember that I had looked at this some time ago and had concluded that the pinout of th ESP32Cam wasn't compatible. Don't remember the details though, and I might be wrong, so please take with a grain of salt. Anyhow, I don't know how to make it work on this board.

I read back some issues, I think problem was that serial UART0 is at GPIO 1 and 3, but never planted what if setup serial after and set to pin 0 and 16

So do we agree that it is not possible with this hardware?
