PC Based Data Acquisition System Using SPI and I2C protocol projects main idea is to implement sensor system which can monitor parameters like temperature, pressure, humidity, light intensity …etc. In general sensors are effected by atmosphere changes but these changes can be converted in to change in voltage.
Data Acquisition refers to reading the data continuously from any sensor. Here we are continuously monitoring the data through PC. We are concentrating mostly on serial communication. The data which we are receiving from the sensor is received by the microcontroller using ADC. Data monitoring is done in PC and for communication serial port communication is used. We can get the information like Date and Time along with our data.
The data that is stored in the PC is easier to monitor or retrieve at any time compared to storing in a particular memory. Nowadays we are using the same process as storing the data in the PC in any kind of industries.

Respected Team,
My name is Aiswarya , a student doing masters in VLSI and embedded systems. As part of my final year project, I have decided to do a project named” implementation of a protocol analyser ” (embedded systems).
In this project, we implement a protocol analyser which is capable of acquiring
data which is communicated between two devices that support 12C protocol ( it could be any communication protocol).This data acquired can be then displayed on PC and analysed.
I really don’t know how this can be implemented, it’s software and hardware requirements, components etc. Please do provide your guidance.
Abstract
A common feature of electronic systems is the need to share
information among two or more components. Engineers have
developed a number of standard protocols that help different
devices communicate successfully. When engineers design an
embedded system, a communication protocol is chosen that will
allow the microcontroller to interact with other devices in the
system. I2C bus ( Inter-integrated circuit bus) is a standard
bidirectional interface that uses a controller, known as a master,
to communicate with slave devices. A slave may not transmit data
unless it has been addressed by the master. With the I2C
communication protocol, data transfer takes place in the form of
messages. Each message has an address frame that contains
the binary address of the slave, and one or more data frames that
contain the data being transmitted. The message also contains
start and stop conditions, read or write bits between each data
frame. Protocol analyzers are used to capture and analyze these
transmitted signals over a communication channel. With the help
of the protocol analyzers, engineers and developers can design,
debug and test their designs through the entire development life
cycle of the product.
