Re: Serve HTML from SPIFFS

is there any example available on esp idf or elsewhere? I am just confused which api's will be usefull for that. I had an issue with creating a burnable file system, which you'll need to do. This link to my issue should provide you with some answers to your question since I went over what I did in ...

xEventGroupSetBits and task scheduler

Does calling xEventGroupSetBits cause the scheduler to immediately check tasks or does it still run at 10msec intervals. Asking for a friend. :lol: My coworker wants to sample the ADC at 1khz. The ADC read is in a task and he uses a 1khz timer callback to call xEventGroupSetBits. I'm thinking that i...

Re: Hybrid NiHM cells as battery source with tons of Amps

What is the voltage rating on the cap? And what voltage do you measure on the cap. Electrolyte/Tantalum caps will blow if you install them with reversed polarity. The first thing I would do is check the output voltage of the LDO and make sure you are using the right part and delivering the correct r...

Re: Hybrid NiHM cells as battery source with tons of Amps

Amps are pushed by the source. That's what voltage does. Looking at the data sheet you use up to 15V on the regulator. So that doesn't seem to be the problem I think your confusion about amps is that they are computed by ohms law, which requires both the output voltage and the input resistance of th...

Re: Write filesystem to spiffs

Can we not get an Espressif engineer to comment on this? I ask because it's part of the official v3.1.1 documentation posted on the Espressif site that this is supported, and it does not work.

Re: Flash memory available

The partition that holds your code in flash is defined by the partition file. You then take whatever flash that isn't being used as defined by the partition file, and create a partition to hold your MP3 files. When you burn the flash with your firmware it shows you how much is being written. You can...

Re: Write filesystem to spiffs

So now I've downloaded the file via HTTP and wrote it to the file system. I can read it back in my application. But if I use esptool to read the partition into a bin file, mkspiffss fails to mount the FS. I am using the latest mkspiffs build and the version info verifies it's built for the ESP32.......

ESP_PLATFORM has been the one I've used, but that one has been removed, at least when building using CMake in current master. There is a PR to get it back: https://github.com/espressif/esp-idf/pull/2601
ESP_PLATFORM works with my release 3.1.1 IDF. Looks like I'll use that for now.
