#MSP432P401R WIRE LIBRARY DRIVER#

The peripherals in MSP432 are similar to those in MSP430, and there is a built-in ROM driver library that facilitates software reuse. The ARM Cortex-M4F architecture used in the MSP432 line allows up to 4 GB of unified program/data/peripheral memory, and has a built-in single precision IEEE754-compatible Floating Point Unit. IEEE754 floating point computations are emulated in software using integer arithmetic on its native 16-bit data, and are quite slow. Furthermore, MSP430 architecture does not include a hardware floating point unit.

The MSP430's 16-bit architecture was already once extended to 20 bits (MSP430X) to accommodate those needs, but the resulting 1 MB limit is still too small, and the instruction set extensions slow down the code execution. Modern embedded computing requires large amounts of data and code, and often calls for floating point calculations. 2 Relationship to other TI ARM Cortex-M devices.Here’s a short video that shows how the graph varies for different lighting conditions. NOTE: Make sure the COM port number and the baud rate is the same as that in the Energia sketch.ĭepending on your lighting condition you should start seeing a plot of the sensor’s lux reading. Plt.pause(.000001) #pause for interval seconds Plt.legend(,, loc='upper right', frameon=True) #place legend in upper right corner of the chart P1, = plt.plot(x0, y0, color='r', linewidth=2, marker='o') #plot x0 versus y0 - red line Plt.title('AMBIENT LIGHT SENSOR DATA', fontname='Comic Sans MS', color='white', fontsize=16) #set a title Plt.ylabel('LUX Readings', fontname='Comic Sans MS', color='white', fontsize=14) #set the label for the y-axis Plt.ylim(0, 12000) #set the y-limits of the current axis Plt.xlim(left=max(0, i-20), right=i+20) #set the x-limits of the current axis

Msp432 = serial.Serial('COM4', 115200) #(port number, baudrate) - create a serial object #Interactive mode may also be turned on via (), and turned off via (). #In interactive mode, pyplot functions automatically draw to the screen.

#MSP432P401R WIRE LIBRARY INSTALL#

Install the following packages: PySerial, Numpy and Matplotlib. P圜harm creates a new Python file and opens it for editing.

Select the project root in the Project tool window, then select File -> New -> Python file -> Type the new filename. Select Pure Python -> Location (Specify the directory) -> Project Interpreter: New Virtualenv Environment -> Virtualenv tool -> Create. If you’ve already got a project open, choose File -> New Project. Let’s start our project: if you’re on the Welcome screen, click Create New Project. > You are working with P圜harm Community. Serial.println(readings, DEC) //LUX ReadingsĭigitalWrite(ledBlue, LOW) //Turn OFF - Blue Ledīefore you begin, make sure that the following prerequisites are met: Upload the below program to the LaunchPad by clicking on the Upload button. The example code can be opened as shown in the figure. Select the correct serial port and board.Įnergia comes preloaded with the example code for OPT3001. It is an easy-to-use plug-in module that offers various analog and digital inputs and outputs at your disposal including an analog joystick, environmental and motion sensors, RGB LED, microphone, buzzer, color LCD display, and more.Ĭonnect the MSP432 LaunchPad + Educational BoosterPack to one of your computer’s USB ports. A light sensor is a sensor that measures the intensity of visible light.

We will be using a MSP432 LaunchPad + BoosterPack (TI BOOSTXL-EDUMKII) to send light sensor (OPT3001) data to PC serially and visualize the data in Matplotlib.

Here’s how you can do this in a few steps! It would look nice if we can represent this sensor data graphically. In general, this is the output response of any sensor on a serial monitor (for example: Arduino) i.e. separated by a new line:
