Using ESP32Cam

I have produced a sketch which I hope may help people to get started programming the esp32cam modules as I personally found it difficult to get started with them but they are really impressive devices especially for the price and well worth having a look. It is for the Arduino IDE and does not requi...

Re: ESP32 WebServer doesn't respond / responds too late sometimes

Hi,

I have experienced this problem on my esp8266 projects and I resolved it by add ing the command: WiFi.setSleepMode(WIFI_NONE_SLEEP);

I have not experienced it with esp32 but maybe the same issue?

Re: ESP32-CAM Problem with not enough pins

Some additional info. on using 1-bit mode on the sd card to free up some io pins: If you access the sd card in 1-bit mode with the command: SD_MMC.begin("/sdcard", true) you can then use pins 12 and 13 as general io pins (although 12 must be low at boot) You can also use the Flash LED on pin 4 no pr...

Re: OTA does not work on AI Thinker ESP32-CAM board

I have used OTA on an esp32cam board but found that for it to work I have to select "ESP32 dev module" instead of "AI Thinker ESP32-Cam" in the Arduino IDE.
also make sure "Partition Scheme" is set to "default 4mb with spiffs" and PSRam is enabled.

Re: ESP32-CAM only saves in FRAMESIZE_CIF

It could be your esp32 camera module doesn't have a psram chip installed in which case the line "if(psramFound()){.." would set it back down to CIF.

Where you able to use OTA with this device?

Hi,
I have used OTA sucesfully with the esp32-cam but instead of selectingthe "ESP32-cam" board in the Arduino IDE, use "ESP32 Dev Module" and make sure PSRAM is enabled and Partition iis set to "default 4mb with spiffs"

Re: problem with settings on esp32-cam module

In case anyone else has this problem I have had a bit of a breakthrough. I think my problems all along is the camera has auto gain and exposure which I am fighting when I try to make adjustments to the image. It is not very clear what many of the settings actually are/do but I now have it working us...

Re: ESP32-CAM Problem with not enough pins

You can use the sd card in "1 bit" mode which means you can then still control the onboard led (gpio4) when using an sd card?
gpio12 and 13 are then not used by the sd card

Re: problem with settings on esp32-cam module

Basically what I am asking is, why does this work? sensor_t *s = esp_camera_sensor_get(); s->set_brightness(s, 0); fb = esp_camera_fb_get(); but this stops both brightness and contrast adjustment working at all: sensor_t *s = esp_camera_sensor_get(); s->set_brightness(s, 0); s->set_contrast(s, 0); f...

Re: ESP32-Cam and SD Card

Hi, Just wanted to confirm that if you start the sd card in "1 wire" mode with: SD_MMC.begin("/sdcard", true) you can then still have full control of the illumination LED :-) I have also included "pinMode(2, INPUT_PULLUP);" - I have not yet tested if this is actually needed on this board? I have jus...
