For Arduino!

Asked chat GPT and here is it's response.

Code: Select all

#include "esp_system.h"
#include "esp_timer.h"
#include "esp_log.h"

More simple, withOUT 3 #include!

Hello,
Can't find how at ArduinoIDE2 with ESP32S3 create and use simple SW or HW Time Counter (aka "stopwatch") without needing any additional libraries etc. No tasks, no interrupt, just count time in seconds from 00:00:00:00 (hr:mn:sc:milsc) at 24hr format maybe with days in front like 01:23:59:59 ...

I've found something useful: https://github.com/stevemarple/IniFile - but its too powerful&bulky.
I need just to open cfg files from SD, read it, set some settings. But I'm completely stuck with all this C++ mess "string String String() char char* etc". Guys, please, help with exact code for:
1 ...

Hello,
Does ESP32S3 + libraries Arduino,WiFI, WiFiClient, WebServer, ESPmDNS = can add lags to another tasks? For example for fast data transferring via SPI? How it's possible to turn them off or put to sleep mode?
Does ESP32S3 Bluetooth and other peripherals which NOT used at Arduino sketch use ...

Because all good (functional, power efficient, not too bulky, etc) libraries for file transferring via Bluetooth 5/LE and USB MSC is absent, this forced me to use "Web HTTP server".

Unfortunately standard sample "ESP32-SDWebServer" is synchronous which means that when anyone connected to this ...

You can certainly read data in with a for loop, and it is highly recommended to read full sectors (512B on an SD card, 4096 for flash) to get the fastest reads. A while(file1.available()) loop will repeat until it reaches the end of the file. If you prefer to read it line by line (slowly), you can ...

By using Bluetooth ;-) I.e. "Bluetooth classic", which is much more different from Bluetooth Low Energy than one would initially think. I don't see how WiFi Direct would solve any energy issues 'normal' WiFi would have. And USB-MSC... is probably the most resource-hungry option, albeit likely the ...

But it's even more true for BLE: BLE provides no "file sharing" protocol out of the box (see e.g. https://github.com/espressif/esp-idf/issues/7025). So instead of using available HTTP server code, you'll have to write your own "file server" protocol on top of BLE, which is somewhat cumbersome given ...

Hello,

I'm the newby so excuse my too simple questions please, but still please help with them.

I need to open config file from SD and then write data to another file at SD.

I'm search at google and find pretty powerful sample but because of lack of experience at this area I just can't understand ...

Running an HTTP server on the ESP is pretty much the standard way to do it. MQTT may also be an option. Plenty of examples for HTTP server (or MQTT client) are available.
Thanks for answers!
Yes, web-http now must be the most used data transferring protocol just because of internet.
But I'm not ...
