WiringPi | Arduino wiring-like WiringPi Library

I have connected a Bright Pi to my Raspberry Pi 3 B and through the use of Unosquare RaspberryIO and WiringPi dotnet I am trying to control the LEDs.

I have followed this Quick Start guide and can confirm the LEDs work based on the steps documented there...

If I run i2cdetect -y 1 on the device I see the following output.

I am calling c++ code from python and I was wondering why I am not getting an integer value back from my function which returns an int. I keep getting None in python.

This is my c++ code:

I have installed windows 10 IoT core on my Raspberry Pi 3B and connect my raspberry pi and my pc to the same connection. but when I want to run a simple program written in Visual Studio 2022. these errors appear:

• The code

This is a project on Raspberry Pi using WiringPi. I have the following three member functions of a template class, along with pure virtuals for read() and write(). This base class is then subclassed by more specialized classes that provide the read() and write() function (sample shown down below):

I have build a prototype board with a STM8L, and I want it to be used and configured as a SPI slave. I am testing it with a raspberry pi as master.

I use the lib provided by ST called "STM8 Standard Peripherals Library" for this, but the documentation is very poor and doesn't expain how to do this...

I can send data from the Raspberry Pi with no issue and receive it on the STM8 but I can't send back any data to the raspberry from the STM8 on MISO.

Is anybody known how I can send back some data to the Raspberry Pi master? Where is my mistake?

Here is the main code:

I have been testing UART communication in C++ with wiringPi.

The problem:

It seems that C++ isn't outputting whole data into the UART port /dev/ttyAMA0. Perhaps I'm doing it the wrong way?

Investigations:

Note : I am using minicom, minicom --baudrate 57600 --noinit --displayhex --device /dev/ttyAMA0 to check the received data.

Also! The UART port, RX & TX pins are shorted together.

The python code worked perfectly however when I tried to implement it in C++, the data received is different.

The expected received data should be: ef 01 ff ff ff ff 01 00 07 13 00 00 00 00 00 1b.

Code used

Python:

I am working on a project on my raspberry pi 4 that uses GPIO.

I cross compiled Qt 5.14.2 and I created a QtQuick application

so I am working with the wiringPi library, I followed this tutorial https://www.youtube.com/watch?v=HxNHlhv74tA and I created a GPIO class that contains a private attribute m_value (it didn't work also when putting my attribute public).

so I created an interrupt (rising and falling) and every time that an interrupt is detected I changed the value of my attribute m_value and a signal was emitted (I check with qdebug that everything is working fine ) and based on the value of the attribute I wanted to change the opacity of a rectangle and it didn't work.

I need to send char* (command) with serial WiringPi. How do I do it if serialPutchar (int fd, unsigned char c) needs an unsigned char?

I have a problem with the following code. I think it's a pointer issue but I don't know how to solve it.

I want to call the SIM7070_Start function from main. This function calls SIM7070_SendCommand and then the error appears. It is related to the 'serial' variable of WiringPi?

please help
