Introducing the MSP430G2553 Hardware

In this example we are going to configure P1. A better approach is to use a dedicated timer.

You are datasheeg using your WordPress. You can achieve the same result as above more elegantly using the delay function that is included in the msp Notify me of new comments via email. The MSPG has two 16 bit timers i. Click here for more detailed instructions. Figure 2 Timer A block diagram. You will notice the first line in the code includes a header file that comes with the Energia Install.

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.

Again this function is convenient for creating short delays especially when initiating peripherals but m430t2553 not be used for controlling program datashset as it is very power inefficient and blocks the CPU. You have tested the install by uploading the blink code.


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 n430g2553 as P1OUT which contains the address of the 8 bit port 1 output register which is directly attached to pins labelled P1.

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.

You can use the system clock to increment the counter. You are commenting using your Twitter account. Your article help me a lot thank you very much!!!

You are commenting using your Facebook account. You can set the upper count value and get the timer to assert an interrupt when the maximum count is reached. Notify me of new posts via email. To test the system we will attach a potentiometer between P1. 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.


You have installed Energia.

Here we are going to use the Energia IDE and the msp-gcc compiler toolchain that comes installed with it. Most simple versions of the blink demonstration use a delay block that is based on making the CPU run many times through a loop doing nothing. To find out more, including how to control cookies, see here: Email required Address never made public. The serial terminal by default assumes that the received binary values are to be interpreted as ASCII characters.

The following example implements both the transmitter and the receiver. Remember characters are simply 8 bit binary numbers that are interpreted as characters using the mapping defined in the ASCII table. The receiver is interrupt based and assumes that a carriage return terminated string is transmitted from that computer. Leave a Reply Cancel reply Enter your comment here
