I am building a PSU and i decided to use an Arduino to control and display voltage and current.
I have made some investigation and I have concluded that I should use An Arduino Uno R3 for controlling
the voltage and current output and a TFT display for showing Voltage set, Current set and Power and other stuff.
I thought of using just the controller and embedd it in my design (after testing and programming).
I could not decide on the Display. I need a colour display, at least 2.4". Should it be a serial one?
Are any drivers available for this kind of display? Maybe with examples?
I have already downloaded the Arduino IDE and getting to know it.
Please advice me how to choose the most suitable hardware.
The Uno is a great way to start, a 16x2 or 16x4 lcd, or a 16x2 lcd shield is a much better way to start.
Most TFT screens and interface boards for the Arduino need the power and number of i/o lines only found on the Arduino Mega2560 board.
There are a few I2C TFT boards, but generally much dearer.
Have seen some folk talking about using then with the Uno, but no idea what its speed/performace is like.
Also depends on what you can buy in your area or wait for the Far East / Ebay ones to arrive.
Plus you need to find if there is a supporting Arduino C++ library for that specific display, otherwise you are faced with a big programing task to get it working.
Maybe this one? I have never used one, but I believe no drivers are needed, you send commands to it over serial. You may need to use the SoftwareSerial library.

I think this is what I will be using.
It is simple to use and with a good resolution.
Also, being serial, can be used with any Arduino model!
Thanks a lot!
