Terminal is the great tool, but sometimes I want nice gui. I decided to start learning C++ Builder and made simple tool for led switching on my devboard with help RS232.
Lets look at USART module in pic microcontroller (uart module).
I’m going to move by two ways:
1. Using existing functions from hi-tech compiler.
2. Writing my own functions.
As you can understand from title, this article is short manual about assembling of device which allows to make connection between your uart device and a PC by COM port.
