Re: freertos mutex semaphore crashing
Try giving the task more stack space. Divide and conquer if you can. Just add one task at a time.

The arduino forum has a post that will do what you want, basically take a picture and ftp it.

Re: ESP_CAM webpage code.
Just to keep things simple use a modified version of the index.html file. Just keep the sensor your using. You will have to modify the main.c file also since the removed index files are referenced there. The number is the size of the html file in bytes. I get the number by opening the compressed, zi...

Re: when the server stop the stream transfering?
Good question. No doubt that the javascript and the camera application is very advanced and not easily understood. The furthest I could get was "stop stream" button on the browser is pressed which runs the stopStream function which executes window.stop command. window.stop command discontinues loadi...

Re: ESP_CAM webpage code.
The html code is compressed and zipped and is stored in camera_index.h file in the project. Based on the sensor you are using that file gets sent to you browser to be rendered. I believe the header tells the browser it is a zip file. Anyways, the browser knows how to handle it. The link below shows ...

Re: ESP32-MINI-1
I checked the board files for arduino and did not see a esp32_devkitM-1 board file but there was a esp32_c3_devkitm-1 json file
So maybe espressif hasn't spun up a board file for that dev kit.

Re: Combination of live streaming and HTTP request for ESP32
What err msgs do you get. I would recommend start with one working then add code little by little until it breaks then fix it. Sometimes can get really confusing. Also the server serves up the html doc so that has to be correct also. Is the led flash code in the html code ? Is the html code in a for...

Re: Can I attach multiple alarms to one Timer?
The timer only allows one alarm value but if you know the alarm values then set your code for the first alarm at 100000, in the interrupt set the alarm for 350000 when that fires set the alarm value for 750000 then when that fires set it to 10000 and the sequence just repeats itself so you get the a...

Re: dual core programming
You can have two tasks that run at different frequencies on the two different cores. For example two timer tasks.
I am assuming you are not talking about clocking the two cores at different frequencies.
