RE: http://www.engineersgarage.com/microcontroller/8051projects/stopwatch-AT89C51-circuit
Dear guys,
What is the best way to display the times in the seven segment on a computer? Is it possible to use a parallel port pins connected to the seven segment display?
Hi Amith
Computers generally communicate serially; so for this you will need a device that could make a serial connection between the microcontroller and computer. The best method is to make use of controller's USART. Also to connect this with the computer's USB port, you will need a USB to TTL device. Now further you will need a serial monitor software installed in your computer that will help you see what the controller sends.
This might help
