Hello all,
Consider the atmega48 microcontroller by Atmel corp. I want to connects its USART to my PC. Basically i want the microcontroller to talk to to computer.
How can i do this?
Thank you
Yes. You need an electrical level translator between the serial port of the chip and the cable to the PC. A representative chip is Maxim MAX232 and its derivatives.
Too complicated.
None sensible, if the idea is to use the serial port of the controller.
Or with a few transistors.
Unnecessary.
Not serial, but parallel port would be cheaper and faster.
ahmed, Now every microcontroller are having the pin connection and corresponding register for serial asynchronous communication (RS232), so you can happly use these facility for your application. But in between (PC - uC) you have to use some level converter (say MAX232), thats it.
