MSP430 Launchpad TUTORIAL
Launchpad processor msp430g2553
This MSP430 launchpad contains msp430g2553 - a small microcontroller in DIP package. In real world you may be using smaller package, but DIP package is great for learning. You should be able to replace this microcontroller with other similar microcontroller for experiments.
Here is a quick pin out of the microcontroller
It is a 20 Pin devic, Pin 1 and 20 being power and ground respectively. You could connect and external crystal at Pin 18 and 19, in case you want to. But the microcontroller, can also operate with its internal clock source.
There are 8 Port 1 Pins that can be used as IO pins. We also have 6 IO Pins on Port 2.
On the launchpad hardware there are two LEDs. The Red LED is connected on Port1.0. Here is the section of the launchpad schematics that shows the microcontroller.
We wil refer to this schematics again as we read the tutorial. For, just keep in mind that we have two LEDS and two input buttons. Refer to the schematics and find which pins are connected to LEDs and Input.
Exercise Questions
1. What port pin is Green LED Connected.
2. What Pin connects to the Switch S2
