After connecting external keypad and display to ARM7 MCB2140,is there any software application to be loaded or executed to make it operate???
A microcontroller won't do anything at all without some code to run!
Thanks for valuable info, and where shall I get the Pin details for connecting keypad and pin details of the prototyping area in the ARM7 Board.
Pin info for the processor from the datasheet for the processor.
Info about the board from the manfucaturer of the board.
How to connect a keypad etc - your own knowledge plus the documentation for the keypad.
