Connecting buttons to MSP430

In this new tutorial, we will see the easiest way to connect a push-button to the MSP430. I will be using msp430 Launchpad for the purpose of the tutorial, however you can use a bread-board too externally interface the push-button Before I begin, I want to tell you the advantage of Msp430 over other sets of microcontroller available in the market.  As you might have seen, msp430 is a pretty cheap microcontroller from the Texas family, and has a 16-bit wide data bus for processing the data but has very few number of pins. Only 2 ports of 8pins each are available for interfacing and that two without support for external crystal. If you want to connect an external crystal, you lose two more pins and that reduces the total… Continue reading
