QUESTION
it seemed too easy. I stored an xml file on a sdcard connected to my esp32.
I use the SD.open()
function to access the files stored on the sdcard. For parsing the xml file I downloaded the tinyxml2 library and tried to use the xmlDocument.LoadFile()
function.
The problem is that the xmlDocument.LoadFile
function is using a std::File
pointer. The SD.open()
function return an fs::File
pointer.
The resulting error message in my ArduinoIDE is:
No matching function for call to
tinyxml2::XMLDocument::LoadFile(fs::File*)
.
Does anybody has an idea how to convert the fs::File*
into std::File*
?
Thank you very much!

as @Galik mentioned, his hint was the key for me. But in the long run @Juraj suggestion to use json the better way.

I am trying to serve a large float array with 8192 values from the ESP32 Heap with the ESPAsyncWebServer library for the ArduinoIDE. The µC is a ESP32 devkit c and I want to access the array with a browser. Here is the code for the array:

QUESTION
I am trying to use the 74HC595 shift register that I got with an Arduino kit in a project for my Raspberry Pi; however, the code that came with the Arduino kit does not make it clear how this would be done, as many of the functions called do not exist in C outside of the ArduinoIDE. The code provided is this:
...ANSWER
Answered 2020-Mar-26 at 22:37Arduino and C do not share the same libraries. Arduino libraries are saved under your_sketchbook_folder/libraries, while C headers are elsewhere. These are also not compatible in that you cannot simply and copy and paste the folders from one to the other. Each dependency has dependencies of its own, and moving the folders in this way leads to more errors.
QUESTION
I've just recently got an NodeMCUv3 ESP8266 and I've been trying to use the Arduino IDE 1.8.8 to program it on my Mac. I've successfully installed ch340* drivers and I can flash the ESP8266 using USB wire cable.
But after flashing the BasicOTA example (modified to connect to my WiFi), I am not seeing my NodeMCU listed as a network port. I only see a list of Serial ports even after restarting ArduinoIDE and NodeMCU.
I tried Bonjour Browser to discover my NodeMCU device and I cannot see it on the net as well.
Could you please suggest any ideas what could be the problem for appearing the network port for NodeMCU device in the ArduinoIDE?

MDNS.update();

QUESTION
I am newbie in C (I'm using Delphi/pascal instead) and trying to get some temperature sensor values and make them equal/fixed size to send to the MCU (with Arduino IDE- so I have to work with C).
Length of data (strlen()) can be 3(like 5.3, 0.9, 0.0 etc), 4(like -4.2, 19.8 etc) or 5(like -15.6) based on temp sensor and below code;
...ANSWER
Answered 2019-Feb-06 at 22:07At least three problems. First, temp_char[]
is declared at size 5, but you're trying to put 6 characters into it with "EEEEE" (which has a trailing zero), and by using temp_char[5]
(only values 0..4 are legal).
Second, the assignment temp_char = "EEEEE"
just changes the pointer, it doesn't actually copy anything into temp_char
. You need strcpy()
or something similar for that.
Third, you're confusing types:

...ANSWER
Answered 2018-Oct-05 at 20:10You shouldn't make a variable named after the tool name and put the EXE's full path in it. You need to edit the variable named Path
there in the list, and add the path to the folder that the EXE is in, followed by ;
, in front of what is already there.
