MSP is a powerful platform provided by Texas Instruments for embedded projects, its versatile nature has made it to find ways into many applications and the phase is still going. Since now, we have covered the basics we can get into more interesting stuff like the communication portal.

In the vast system of embedded applications, no microcontroller can perform all the activities by itself.

Each communication protocol has its own advantage and disadvantage. I2C is a synchronous communication protocol meaning, both the devices that are sharing the information must share a common clock signal. It has only two wires to share information out of which one is used for the cock signal and the other is used for sending and receiving data.

I2C communication was first introduced by Phillips. As said earlier it has two wires, these two wires will be connected across two devices. The advantage of I2C communication is that more than one slave can be connected to a Master.

At any given time only the master will be able to initiate the communication.

Since there is more than one slave in the bus, the master has to refer to each slave using a different address. When addressed only the slave with that particular address will reply back with the information while the others keep quit. This way we can use the same bus to communicate with multiple devices. The voltage levels of I2C are not predefined. I2C communication is flexible, means the device which is powered by 5v volt, can use 5v for I2C and the 3. But what if two devices which are running on different voltages, need to communicate using I2C?

In this case voltage shifters are used to match the voltage levels between two I2C buses. There are some set of conditions which frame a transaction. After this all devices on the same bus go into listening mode.

So rising edge of SDA stops the transmission. Each bit is transmitted on each clock cycle, so it takes 8 clock cycles to transmit a byte. This ACK bit is generated by either slave or master depending upon the situation. It is certainly reliable to an extent since it has a synchronised clock pulse to make it smart.The timer IC is an integral part of electronics projects. Be it a simple project involving a single 8-bit micro-controller and some peripherals or a complex one involving system on chips SoCstimer working is involved.

These provide time delays, as an oscillator and as a flip-flop element among other applications. Introduced in by the American company Signetics, the is still in widespread use due to its low price, ease of use and stability. It is made by many companies in the original bipolar and low-power CMOS types.

Depending on the manufacturer, the standard timer package includes 25 transistors, 2 diodes and 15 resistors on a silicon chip installed in an 8-pin mini dual-in-line package DIP Variants consist of combining multiple chips on one board.

However, is still the most popular. Let us look at the pin diagram to have an idea about the timer IC before we talk about timer working. Output of the timer totally depends upon the amplitude of the external trigger voltage applied to this pin. Overrides TRIG which overrides threshold. Open collector output which may discharge a capacitor between intervals. In phase with output. Positive supply voltage, which is usually between 3 and 15 V depending on the variation.

For a timer working as a flip flop or as a multi-vibrator, it has a particular set of configurations. Some of the major features of the timer would be. The generally operates in 3 modes:. This means there will be no stable level at the output.

So the output will be swinging between high and low.

This character of unstable output is used as a clock or square wave output for many applications. This configuration consists of one stable and one unstable state. The stable state can be chosen either high or low by the user.

If the stable output is set at high 1the output of the timer is high 1. At the application of an interrupt, the timer output turns low 0. Since the low state is unstable it goes to high 1 automatically after the interrupt passes.

Similar is the case for a low stable monostable mode. In bistable mode, both the output states are stable.They are low power suitable for battery powered devicesinexpensive, easy to interface with and are insanely popular among hobbyists. And as a bonus it even looks cool, like a pair of Wall-E Robot eyes for your latest robotic invention!

Ultrasound is high-pitched sound waves with frequencies higher than the audible limit of human hearing. Human ears can hear sound waves that vibrate in the range from about 20 times a second a deep rumbling noise to about 20, times a second a high-pitched whistling. However, ultrasound has a frequency of over 20, Hz and is therefore inaudible to humans.

The one acts as a transmitter which converts electrical signal into 40 KHz ultrasonic sound pulses.

The receiver listens for the transmitted pulses. If it receives them it produces an output pulse whose width can be used to determine the distance the pulse travelled.

As simple as pie! Since it operates on 5 volts, it can be hooked directly to an Arduino or any other 5V logic microcontrollers. Trig Trigger pin is used to trigger the ultrasonic sound pulses. Echo pin produces a pulse when the reflected signal is received. The length of the pulse is proportional to the time it took for the transmitted signal to be detected. In response to that the sensor transmits a sonic burst of eight pulses at 40 KHz.

The eight ultrasonic pulses travel through the air away from the transmitter. In case, If those pulses are not reflected back then the Echo signal will timeout after 38 mS 38 milliseconds and return low. Thus a 38 mS pulse indicates no obstruction within the range of the sensor. If those pulses are reflected back the Echo pin goes low as soon as the signal is received.

The width of the received pulse is then used to calculate the distance to the reflected object.

This can be worked out using simple distance-speed-time equation, we learned in High school. In case you forgot, an easy way to remember the distance, speed and time equations is to put the letters into a triangle.

We will use the below equation. Here, we have the value of Time i. What speed do we have? The speed of sound, of course! You could do the math, but searching it is easier.

Anyway, with that information, we can calculate the distance! But this is not done! Now that we have a complete understanding of how HC-SR04 ultrasonic distance sensor works, we can begin hooking it up to our Arduino! Start by placing the sensor on to your breadboard.

Instead of triggering the ultrasonic sensor and measuring the received signal pulse width manually, we will use a special library.

Download the library first, by visiting the Bitbucket repo or, just click this button to download the zip:. If you need more details on installing a library, visit this Installing an Arduino Library tutorial. The NewPing library is quite advanced and it considerably improves upon the accuracy of our original sketch. It also supports up to 15 ultrasonic sensors at once and it can directly output in centimetres, inches or time duration.In the previous tutorial, we have seen the basics of Microcontroller like its history, features, packaging and few applications.

In this tutorial, we will continue further by looking at the Microcontroller Pin Diagram and Microcontroller Pin Description along with some other details like the basic circuit of the Microcontroller. We will first see the Microcontroller Pin Diagram and Pin Description as it will be easier to understand the architecture later in the next tutorial.

Pin Diagram or Pin out of a device will specify the pins of an electrical connector along with its functions. The pin orientation of an Microcontroller may change with the package but the Pin Configuration is same. The following image shows the Microcontroller Pin Diagram for these packages specifically. Now that we have seen the Microcontroller Pin Diagram, we need to understand the functions of these pins.

Hence, we will now see the Microcontroller Pin Description. The Pin Description or Pin Configuration of the Microcontroller will describe the functions of each pins of the Microcontroller.

Let us now see the pin description. During this time, the oscillator must be running. Generally, a Quartz Crystal Oscillator is connected here. It represents 0V and is connected to the negative terminal 0V of the Power Supply.

Additionally, when external memory is interfaced, PORT 2 pins act as the higher order address byte. PORT 2 Pins have internal pull-ups. Using this pins, external Program Memory can be read. Using this Pins, external address can be separated from data as they are multiplexed by Code from external program memory can be fetched only if this pin is LOW.

For normal operations, this pins is pulled HIGH. Now that we have seen the Microcontroller Pin Diagram and corresponding Pin Description, we will proceed to the basic circuit or schematic of the Microcontroller. The following image shows the basic circuit of the Microcontroller. This basic circuit of microcontroller is the minimal interface required for it to work. The basic circuit includes a Reset Circuit, the oscillator circuit and power supply.

Let us discuss a little bit deeper about this basic circuit of Microcontroller. First is the power supply. Next is the Reset Circuit.Optional external power adapter provides a maximum of mA or 2.

Enter your project name, select family as MSPand now variant is mspg Remember, this is a critical step.

To check your option, refer your chip on the Launchpad. It has a mentioned of the variant. For all the tutorial, I will be using mspg as the chip, so kindly change accordingly. In the bottom box, select Empty project with main.

Getting started with CCS for Launchpad - MSP430 (MSP430F5529)

Have a look at the basic structure of the code already written. The first line is your header file that depends upon the variant; you choose while creating your project. Next step is the main function. Inside the main function you can see, initialization of watchdog timer. The MSP and many of the new generation microcontroller includes a special timer called the Watchdog Timer. However, many developers used this timer in a scenario when they want to reset the controller when certain conditions are met.

For now remember to turn off the watchdog timer, as we will discuss it when we talk about timers in the tutorial. Now, here comes the task we want to do i.

Since the leds are on port1 and on pin 0 and 6 respectively, we will first have to make this pin or declare these two pins as whether they are acting as output or input. Here comes the use of P1DIR register.

P1DIR register is responsible for making your pins as output or input. Since we want to configure pin 6 and pin 0, we assign P1DIR as.

Next is to specify the particular pin of the particular port as high or low. For that, you can use P1OUT as the register. Since we are initializing things, I set the led on P1.

Next is the infinite while loop, in it there are two steps. First is toggling and other is providing a delay after each toggle to see the toggling effect successfully. This will reverse the state of pin6 and pin0. So initially pin6 was low it will become high, and pin0 will become low. This process would go on continuously.Page of Go.
