How to use CCS (CODE COMPOSER STUDIO)

1. Double click on the CCS icon and start execution of code composer studio. The default

location of where the projects are stored is given and can be changed to another location. Use

the default location given.

2. To create a new project, select from the File menu, Project and then Other (File -> project ->

other). Next, select CCS Project.

3. Select the desired project name and the desired version of the MSP430. For the experimenter

board it‟s the MSP430G2553. Also select the type of project: Empty C program, a Hello

World C program, or an Assembly Language program.

4. Highlighting the project makes it the active – debu g project. Also, clicking on the left arrow

opens all of the subdirectories and files associated with the project. Selecting main.c will

open the C language source file.

5. To build and compiler a project, select the Project menu and then the Build Project option.

CCS will then build the project and indicate if there are any errors that need to be corrected.

6. To debug a project, the debug option must be selected under the Run menu and the

experimenter board must be connected to the desktop. The Build Project and Debug options

should be selected every time the program source code changes.

7. To execute the program, the Resume option under the Run Menu is selected.

8. To quit the program, the Terminate option under the Run Menu is selected

PIN DIAGRAM OF MSP430G2553






MSP430F2013 TRAINER KIT






Note:

PxSEL --> configure the function of the I/O

PxDIR --> selects INPUT or OUTPUT mode

PxOUT --> If the pin‟s pull−up/down resistor is ena bled, the corresponding bit

in the PxOUT register selects pull-up or pull-down. Bit = 0: The pin is pulled

down

Bit = 1: The pin is pulled up

PxREN --> Each bit in each PxREN register enables or disables the

pullup/pulldown resistor of the corresponding I/O pin. The corresponding bit in the

PxOUT register selects if the pin is pulled up or pulled down. Bit = 0:

Pullup/pulldown resistor disabled

Bit = 1: Pullup/pulldown resistor enabled

Timers and Clocks and PWM

A clock in embedded electronics is what controls how fast the processor ticks. The MSP430 has

multiple clocks which can used for the peripherals and the CPU. MCLK is the master clock for the

CPU. SMCLK is the submain clock. Both of these can be selected for use in the peripherals such

as an ADC or Timer. Why so many clocks? Power efficiency. Different clocks are turned off in different low power

modes; for example LPM0 disables MCLK and the CPU but leaves SMCLK running so the

peripherals hooked up to it can continue to run. These clocks can be generated from a number of

different sources and can also be divided down from the clock input. The Timer keeps track of how many clock cycles pass without having to write specific code to

keep track of time. This can be useful not only for low power modes, but also for time sensitive

projects. To keep it simple and quick, a timer needs to be initialized and enabled. It will then

proceed to count as the clock ticks to a predefined value and then start over. You can set the Timer

to generate events at multiple times along the way to its end value; these events could be an

interrupt when it hits a certain number of clock ticks, or it can toggle, set, or clear a specialized

pin. Having the Timer change a pin without calling any interrupts or any specialized code is the

best way to create a simple PWM.

What is PWM? Pulse Width Modulation. As far as we are concered, it is a square wave that has a

duty cycle at a cetain frequency. Duty cycle is the percentage of time the wave is high across one

period. How is it useful? Motor control, light control. Think of an LED, the lower the duty cycle

(the less its turned on over a period of time), the dimmer it is. There are countless numbers of

applications for using PWM.





TITLE: Working with CCS. GPRECD/EEE/LVC(P)-Introduction Date: 18-04-2019

More about the Timer

There are a few things are required to know before start coding. The Timer counts clock ticks, in

reality it can be that simple, but it does not need to be. For example the Timer can count up to a

certain number or count up then down. The different functional modes are as follows 1. Up Mode - the Timer repeatedly counts from 0 to the value set in register TACCR0 2. Continuous Mode - the Timer repeatedly counts from 0 to 0xFFFF 3. Up-Down Mode - the Timer repeatedly counts from 0 to TACCR0 and back down to 0

The picture above is a visual representation of Continuous mode

As a programmer Up Mode the best, so it will be using that to build the PWM library. So you can

set up an interrupt for when the timer gets to TACCR0 or TACCR1, or you can toggle one of the

timer.

Setting up the Timer

First we set up our PWM pins. The code below sets P1.2 to output and enables the pin to be the timer output bit TA0.1.

P1DIR |= BIT2; // P1.2 to output P1SEL |= BIT2; // P1.2 to TA0.1

Next we have to set up the CCR0 and CCR1 registers, which determine when events happen and

how high the clock will count to.

CCR0 = 1000-1; // PWM Period CCTL1 = OUTMOD_7; // CCR1 reset/set CCR1 = 250; // CCR1 PWM duty cycle (25%)

Remember, the timer depends on the clock frequency it is running on. So if you have a 1MHz

SMCLK and want a PWM frequency output of 100kHz, CCR0 will have to count up to 10






leaving only 9 values for CCR1 to toggle the clock at. This limits the resolution the duty cycle can

have. The default DCO (digital controlled oscillator) which is the source of the MCLK and in this

case the SMCLK is approximately 1.1MHz, making the PWM frequency about 1.1kHz with a duty

cycle of 25%.

Setting CCTL1 = OUTMOD_7 does two things, one of which might not be so apparent.

OUTMOD_7 is the Reset/Set option,which means "The output is reset when the timer counts to

the TACCRx value. It is set when the timer counts to the TACCR0 value" (From User Guide).

This means that when the timer hits CCR0 it starts counting over AND sets the PWM output to 1;

this also means that when the timer hits CCR1 it will set the PWM output to 0. For this PWM program we will be using SMCLK and Up Mode for the timer. Now we have to set

which clock and which mode the Timer is going to use. The following line of code sets the clock

and the mode of operation.

TACTL = TASSEL_2 + MC_1; // Chooses SMCLK, and Up Mode.

In this register you can also set the interrupts to be triggered but we will not be doing that here

since the PWM pin will be toggled without needing an interrupt.
