Thanks for posting this project Vivek, Very informative. Are there any serial ports other than the port that is configured as the terminal? I wonder If I can do a 9-bit serial stream on the Pi? So many questions!!

Thanks again,
Glenn

Also, if I run the program in python, it gets stuck when I read from or write to the uart.

In reply to Misha. Yes, you can use UART communication, but you should use lowest baud rate.

I am planning on sending integer data over a 433Mhz RF kit using 2 RPi’s. Now I have searched for a very long time and cannot find valid information. Please can you help.

I want to send numerical data(integers or floats perhaps) over the 433Mhz RF link kit using the UART pins. Now the data sent is constantly changing in an infinite loop.

1. I assume if I change the parameters defining what “data” is (referencing above code) then I could transmit anything?
2. What is the code for the receiver? what code can I use to read the numbers that I sent through?

All my code is in python like above and would like to keep it such
Any help would be appreciated.

Misha

In reply to Mayke Santos. Hi, Above tutorial not explaining to control your Pi through UART. It just shows how to use UART. We need UART communication for a lot of applications.
