Electronics - Serial Communication Between AVR


Expert: Apurv - 9/9/2009

Question
Hi Apurv;
I want to transfer data between 2 AVR microcontrollers and I have just 3 pins to do this.
I think I must use I2C or Software UART.
I use Bascom AVR.
Can you help me please?

Answer
u can use UART or USART.
You need only three pins of serial communication. One for transmitting the data, another is for receiving data and third one in common (ground).
Check the datasheet of the AVR you are using and use the required instructions.
