In this Code Composer Studio graphing tool tutorial, graphing variables will be demonstrated in Texas Instruments IDE. The process is fairly straightforward and will be shown in a video as well as some screenshots so it can be easily replicated.

In this switch debouncing tutorial part 2 C code debounce algorithms will be looked at further, and their effectiveness. All the software solutions shown will be demonstrated on the MSP430G Launchpad. However the basic principle of operation shown in the examples, can be applied to all microcontrollers, particularly the last example which is based on some code found at Jack Ganssle tutorial, this can be easily implemented on any system using the C language.
In this switch debouncing tutorial part 1 the cause and effect of switch bounce will be explained and demonstrated, then a cost effective hardware debouncing solution will be discussed, with oscilloscope captures to demonstrate the results. The last section of part 1 will show a simple program based on the MSP430 , this can be used to see the effects of a particular switch connected to the GPIO. Switch deboucing tutorial part 2 of this tutorial will look at further C code debounce algorithms and their effectiveness.
Microcontroller GPIO protection is an essential element of any circuit design.
GPIO ports generally have maximum voltage and current ratings, if these are exceeded it can result in the microcontroller being damaged or completely destroyed.
