Re: SPIFFS Preferences and a file open simultaneously?

Hi

Great, thanks!

Another question then.

If I erase and init NVS using

Code: Select all

nvs_flash_erase();
nvs_flash_init();
will files stored in SPIFF, be erased, or will they remain?

SPIFFS Preferences and a file open simultaneously?

Hi

I am using SPIFFS with Preferences and files. Can I have a Preferences storage and a file open at the same time? Or do I need to close the Preference storage before I open a file, and vice versa?

Task scheduling, how does it work in this case?

Hi I have inherited some code using Task scheduling that I am not very familiar with and here's a section of code I can't quite wrap my head around. The code is running on an ESP32-WROOM, DevKitC V4, and I am using the Arduino IDE. There's a lot of code in several files, so I can't include it all he...

HIgh speed GPIO

Hi I have noticed that there are some different libraries and software out there that makes the ESP32 output VGA. One lib offers 640x480 resolution at 60Hz framerate. So this means a pixel rate of more than 18MHz, or about 50 nS per pixel. While the ESP32 is also doing other stuff. So I made a simpl...

Re: Some devices gets timeout trying to access webserver via WiFi.

This is NOT a signal strength issue. The ESP32 is using a high quality external antenna and all units are tested in close range. Some further tests seems to indicate this is related to the Wifi part of the ESP32 system, rather than the Webserver as could be intuitively suspected. But I've tried thre...

Some devices gets timeout trying to access webserver via WiFi.

Hi I have setup an ESP32-DevKitC with WiFi and Webserver.h I run the ESP first as an AP, and then as a client connected to my local WiFi network. As an AP I can connect to the WiFi AP with all my devices, but some android phones gets timeout when I try to access the webserver, Ping does also not wor...

How to get the max speed out of ESP32 for hardware related tasks?

Hi Sometimes you really don't now how well something will work, and then you just have to try it out. This is one of those occassions. So, considering the ESP32-DevKitC I happened to have lying around runs at a clockspeed of 260MHz, I figured it could do some pretty neat things, fast. So I wrote thi...
