Have you tried the steps from their ESP Setup Guide?

I managed to get it working.

After I had some trouble with the spiffs from your link I found a newer version of the mkspiffs tool
changed back to the official spiffs implementation and now it works.

Thanks for your help.

Hmm maybe I should try the third party SPIFFs.

However I was talking about the SPIFFs version that is integrated in the newer ESP-IDF not any other third party SPIFFs but perhaps it will work with them. Gonna try that.

Did somone of you manage to use the mkspiffs tool and the official spiffs implementation together? I created a folder containing two files on my pc and followed the steps descriped by the documentation for creating and uploading the spiffsimage.

Again sorry for the longer delay, I have tried it out and it seems to work. https://i.imgur.com/TIZNsMJ.png No longer delay between the transmission only the smaller 10µSec delay during the queueing. The code should be "super fast" now :D. However the flickering is still there. Maybe its because I a...

Does that mean one can within Arduino dedicate a task (or routine as i see it) to one of the two cores also?

Yes you can

Ok this makes sense. So I do have to get the result of a transaction before I can reuse it? I gonna try that out this evening. When it is right that getting the transaction result using spi_device_get_trans_result results in a task switch then it would make it even slower because then after each que...

Sry for the longer delay. This sounds like a good idea. Is there a way to check if a used transaction hadle that was queued is finished? I tried to use the post_transmission_callback where I set the user field of the handle back to NULL. On function side I loop through all of the 12 and check whenev...

Good evening everybody, currently im writing on a driver for my TFT display and run into some problems. The basic concept behind my code is the following: I have an array with 12 instances of the "spi_transaction_t" struct as transmission buffers. When drawing on the displays the first thing that ha...

It totally depends on what you are trying to archive.

The "problem" with the esp-idf is that there are way fewer libs you can use than when programming via arduino.
In some cases you end up in having to programm them by yourselfe.

Give us some examples of what exactly you want.
