RPi 3 UART for RS232
I just got my RPi and after some time toying around I started a project. But I encountered some problems with the useage of the UART at the RPi 3.
Because of this problems and the fact that I found different methods on the web depending on which packages are used I used apt-get update + dist-upgrade. If i now type "uname -a" I get the following output:
Linux raspberrypi 4.4.13v7+ #894 SMP Mon Jun 13 ...
What I want to do is communicate with a device over RS232 protocol at a baud rate of 9600.
As I understood this there are 2 UARTs on the RPi 3. One connected to bluetooth and a different one (mini UART).
There are overlays to switch the UART which is connected to bluetooth back to the pins 14 and 15.
But do I really need to do this if I use a baud rate of only 9600?
If not is the mini UART the device ttyAMA0 or the other UART?
Does anybody know an example program + setup for RPi 3 with the current version or some kind of To-Do list for working with the UART?
I tried different configurations with the program from http://www.raspberry-projects.com/pi/pr ... g-the-uart but could not get any output at the Pins 14 and 15. I looked at the pins with a logic analyzer.
As I said I'm new to the RPi and if i missed something important please tell me.
