In this tutorial I will demonstrate a MSP430 voice control over Bluetooth, using a HC06 Bluetooth module. I will be using an Android App I programmed which can be downloaded and installed, the C code for the MSP430 is also downloadable at the end of the tutorial.
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.
In this second part of the MSP430 programming tutorial examples of GPIO register settings will be shown and explained. Additionally register examples for some of the internal peripherals will be demonstrated and explained. The first part of the tutorial can be found here.
In this MSP430 programming tutorial part 1 some of basic C operators used for programming the MSP430 will be looked at. The GPIO port registers will then be looked at in greater detail. In part 2 example code for the GPIO registers will be shown and explained, as well as examples for the the ADC peripheral register. The MSP430G2253 Launchpad will be used as the reference microcontroller, the primary IDE used is Code Composer Studio (CCS). The MSP430G series family guide, as well as other useful information can be downloaded directly from Texas Instruments webpage here.
In this MSP430 timer PWM tutorial the basic workings of the on board timer peripheral will be explained, along with some C code examples which can be downloadable at the end of the tutorial. Additionally the video below demonstrates the examples ‘A picture paints a thousand words, a video displays a thousand pictures’.
In this C2000 Programming Model Guide, the two basic approaches to programming on the C2000 will be over viewed using the C2000 Launchpad. Some code examples will be shown, as well as a code execution speed test comparing the two methods. All the code is written in Code Composer Studio (CCS) v5.5, with the latest version of ControlSuite released at the time of this article being posted.
