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 MSP430 Launchpad used as a programmer tutorial, the MSP430 Launchpad board will be used to program a MSP430G2230 microcontroller. The MSP430G2230 is an 8 pin microcontroller and comes in a Small Outline Integrated Circuit package (SOIC), so offers the developer the chance to reduce the overall footprint of the project on a budget. As the MSP430G2230 comes in a SOIC package, for prototyping it’s often easier to increase the package size, which allows more conventional and off the shelf components to be used during the development stage. Texas Instruments sells a Dual In-Line Package or DIP adaptor PCB, the image below shows the board and it can also be found here.
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.
The EagleCad Tutorial Grid Size Unit Setting will cover how to edit the EagleCad eagle.scr script file. If you use EagleCad and find you want to use Mils or mm, or simple want to change the default grid settings, then this tutorial will show you how. There is also some basic information on this on the EagleCad FAQ’s page located here.
In this fourth and final part of the C2000 Solar MPPT Tutorial, the system set-up and testing will be looked at. This will involve the overall hardware set-up for testing, ADC calibration, reduction of noise on the ADC sampling, efficiency test and some improvements for future iterations. The final C2000 solar MPPT tutorial C code is also downloadable at the bottom of the page.
In this third part of the C2000 Solar MPPT Tutorial, the software will be looked at in greater detail. This will entail a look at the Perturb & Observe algorithm, ADC code and timing code to ensure everything operates in a controlled manner.
In this second part of the C2000 Solar MPPT Tutorial, the hardware and circuit design will be looked at in greater depth. The schematic for the system is posted again below for reference, which can be enlarged by simply clicking on it.
