Re: The MagPi does C :-)

utter [MOD EDIT - PROFANITY REMOVED], surely tutorials exist somewhere especially about wiringPi, and other ones may exist at other places about different subjects. I already wrote that above: "For a MagPi C vol.II , of course one could set up on existing tutorials, e.g. wiringPi, and even API lib d...

Re: The MagPi does C :-)

yes, of course, among others, it was a wiringPi tutorial about GPIO LED blink and pwm and i2c for an MCP23017. And it was by working on a given (already fine working) code about Pi-to-Arduino i2c and UART communication. The goal was of course, to make that chip or the Arduino work with the Pi by C p...

Re: The MagPi does C :-)

I doubt that people using a Pi and using C just do that because they want to learn C. They want to become able to use C to achieve some practical goals, so C is not the goal, C is just a tool, means for the purpose. The same it's basically about Python or Scratch or perhaps Java or C#. So a C tutori...

@Gordon: I know that you have your own website providing tutorials, and I know that on github there are just forks, but my conditionally unreal assumption was: what would be if there was just something on github and no tutorial?

Re: The MagPi does C :-)

I personally have some basic skills for C - the question is, how to program one's projects requiring different hardware drivers and different software libs. And as there are Python tutorials for the Pi (to graphics, openCV, HATs, a.s.o.), one would need similar C/C++ tutorials. Also your wiringPi li...

the crucial question is: how to utilize one's C skills if the Raspi (org) dosn't support C programming, at least hardly not worth mentioning? here's 2 other topics which point out to what is needed now to be able to use C for the Pi: heaps of tutorials to applied C programming! https://www.raspberry...

Re: i2c pin availability

what a pity for the Pi3 users, and what a waste - at least it must be optionally switchable.
And finally: why is it led out, when it's just internal?
I'll stay with my Pi2s then as long as possible, a Pi3 would actually be a downgrade then.... :|

Re: from Pi: access files located on PCs in Windows workgr

the same for me, it's just for my personal purposes, and I have nothing to hide from myself on my Pi or on my PCs.
But how networking works - no idea, neither in Windows workgroups nor in domains nor with or without Pis. It simply just should work.

Re: Rpi UART to Arduino.

for the void loop() I would suggest instead:

Code: Select all

void loop() {
  if( Serial1.available() ) {
     // delay(10); // allows more serial data to be received together
     while( Serial1.available() ) {
        int data = Serial1.read();
     }
     Serial1.write(data);
