[binu G]

I have two controller in my design.
i plan to use SPI interface between the controllers

is there any other method to make the programmer life easy ?

U can use usart or uart (like RS232, CAN, I2c), if ur controller supports...

Hello!

If the design is not finalized, then the best method to make the programmer life easy
is to replace both microcontrollers with a bigger one.

Hi,
Your possibilities include UART, SPI, I2C(TWI), One-Wire Interface, etc. Since there are only 2 controllers, I think UART would be easiest. There are UART modules in many controllers (you haven't told us which you are using), so programming it isn't too difficult, and it only requires 1 wire for unidirectional communication (master to slave) or 2 wires for bidirectional communication.

Hope this helps.
