frame2bmp outputs Microsotft Bitmap, not RGB888. It just so happened that the BMP file contains actually RGB888 after the header

here is some more info on the 54 bytes: https://en.wikipedia.org/wiki/BMP_file_format

BMP files have a header before the pixels that have info on what that image is, what resolution and more. If you need only the pixels, skip the first 54 bytes. If you want to open the BMP on a computer, do not skip them :) Grabing in JPEG and converting is possible because it happens in a thread and...

I'm not very good with explanations, but I will do my best here. 1. ESP32 is MCU, not a computer. As such it has limited amount of memory and processing power. 2. It is just not technically possible to acquire all of the bytes necessary for 888 and write them to the PSRAM chip. Even on resolutions h...

There is a branch in the arduino repository for IDF4.0 that you can try, but to answer your question, wee will skip 4.0 and go directly to 4.2 (current IDF master) because of support for ESP32-S2. If you want to try that, there is an "esp32s2" branch that you can checkout

It's already added, just not in the master branch. Check the arduino repo for "esp32s2" branch and give it a go. Be warn that it's a work in progress so some things might be broken.

OK So I see two issues.

1. You should use SDMMC on Wrover-Kit
2. If you want to use SPI and use the LCD as well, you need to init first a new SPI port (HSPI) and then init the SD card to use that port.

LCD and SD do not share pins and the SPI port is going to the device initialised last.

You are not sending a response to the request in the alarm handler You must request->send(response) in every handler.

The exposure settings on those sensors is actually measured in lines. So for max res of 1600x1200 you can expose for the whole duration of 1200 lines. Not sure if that makes any sense :). For smaller resolutions you get less lines and less exposure. There are 3 main resolutions from which all others...

Hi Lucas, As far as I can understand, you want to collect all frames in the loop and give the latest to the web server. Am I correct? I will continue based on that assumption :) You should not use busy loops inside threads, instead you should use one of the FreeRTOS objects that allow for threads to...
