Kikus The Mars Atmosphere and Volatile EvolutioN or MAVEN mission will orbit Mars to explore how the sun may have stripped Mars of most of its atmosphere, turning a planet once possibly habitable to microbial life into a cold and barren desert world. TI also provides periodic free automatic updates to CCS. Learn how your comment data is processed. Using the Timer Interrupt Before working with timer A, review the section on interrupt vector addresses located in the datzsheet sheet and the timer A section in the user guide. The primary science instrument on Explorer 1 was a cosmic ray detector designed to measure the radiation environment in Earth orbit.

Melkree In this example we are going to configure P1. Most simple versions of the blink demonstration use a delay block that datqsheet based on making the CPU run many times through a loop doing nothing.
You have tested the install by uploading the blink code. Click here for more detailed instructions. You are commenting using your Twitter account. The receiver is interrupt based and assumes that a carriage return terminated string is transmitted from that computer.

You have installed Energia. You are commenting using your Facebook account. To test the system we will attach a potentiometer between P1. The serial terminal by default assumes that datasbeet received binary values are to be interpreted as ASCII characters. The MSPG has two 16 bit timers i. By continuing to use this website, you agree to their use.
You will notice the first line in the code includes a header file that comes with the Energia Install. Here we are going to use the Energia IDE and the msp-gcc compiler toolchain that comes installed with it. You can achieve the same result as above more elegantly using the delay function that is included in the msp Figure 2 Mg A block diagram. Again this function is convenient for creating short delays especially when initiating peripherals but should not be used for controlling program flow as it is very power inefficient and blocks the CPU.
Notify me of new comments via email. Often we would like to control the amplitude of an output signal to vary for example the brightness of an LED or the control the speed of a motor. A better approach is to use a dedicated timer. This header file is developed by the chip manufacturer and defines all the hardware addresses in the chip and control bits with easy to remember mnemonics such as P1OUT which contains the address of the 8 bit port 1 output register which is directly attached to pins labelled P1.
You can set the upper count value and get the timer to assert an interrupt when the maximum count is reached. Remember characters are simply 8 bit binary numbers that are interpreted as characters using the mapping defined in the ASCII table.
The disadvantage with the approach is that while the CPU is running through the while loop just to provide a delay it cannot be doing something else of indeed sleeping to to save power. A PWM signal is a pulsed signal with a period that is chosen to be much faster tun the response time of the device of system that you want to drive.
Figure 1 20 pin device pin functionality. To program in c with Energia you simply delete the Energia code that appears when you open a new project and then open a new tab using the drop down arrow in the Energia toolbar.
