Re: Issue after running apt-get upgrade command , keyboard and mouse not responding upon booting

I am using Raspberry Pi model since last one year. Which model? There were several Raspberry Pi models available last year, knowing exactly which model you have could help. Model is Pi 3 Model B For power supply I am using the normal 110 V regular power supply. This tells me nothing. What is "the n...

Re: Solved it!

For those who are having similar problem as me, I would like to tell you that I have found the solution. Although it shouldn't make a difference, but my compilation was clear, when I used the header #include <RF24/RF24.h> before the other headers. Also, turns out that the syntax I was using for com...

Re: ERROR : setup my raspberry pi to receive message from Arduino using C++

What includes you have won't affect which libraries get linked (though if the headers were different then the mangled name could be different). Looking at your original compile line from the first post you appear to be linking against librf24 which I would assume should have the functions in it. Th...

That C++ program in your post has ZERO chance of ever working on any Raspberry. You've got code that isn't written for Raspberry hardware. It's not an Arduino microcontroller, it's a general purpose Linux computer. Dougie , I have seen few code construct where it works perfectly fine.. Please ref t...

You probably want to use UTF-8 on the Arduino rather than Unicode. https://playground.arduino.cc/Code/UTF-8 Thanks ! I will look into it.
