On March 26, 2014, I delivered two sessions of my seminar "Embedded Systems and Robotics using 8-bit and 32-bit Microcontrollers". Each session had an audience of about 200 students of Electronics and Communications Engineering (ECE) stream of Bachelor of Engineering (BE) program. These were all either 3rd year or 4th year students.
The seminar started with a discussion on what are Embedded Systems and where we can find them in our daily life.
After that a brief analysis of generic Embedded Systems and their application areas was presented. After this a brief introduction to Robotics was given.
A demo of an simple obstruction sensing robot was given. This robot detects obstructions closer than 50 cm or less. If the robot detects an obstruction it stops, reverses for some time and then turns left while going forward and starts looking for the next obstruction.
The demo was followed by an explanation of the robot's components and its working.
Then the most interesting section, How to learn Embedded Systems was delivered. This section covered both Hardware and Software areas of learning.
This was followed by a brief introduction of 8-bit and 32-bit microcontrollers and their advantages & disadvantages. The seminar concluded with a discussion on skills and knowledge that Embedded Systems industry is looking for in its future employees.
The second and final demo was of the HID USB Mouse implemented using ARM9 based NXP2148 microcontroller. Here's a link to the video of the HID-Mouse.

Next batch of Embedded Linux and Linux Device
Driver training course is scheduled to start in month of March 2014.
This training is very effective for those developers who are working in
Linux and C development and want to learn higher skills in the same
Designed for working professionals - Working professionals who need a change in job level should join
this course. Morning classes on weekdays, before office hours.
I am starting a new batch for Embedded Systems Design training. It will start in March 2014. This is going to be weekend-only batch.
The syllabus includes C refresher, 8051 microcontroller architecture, Assembly programming and Embedded C programming. Interfacing 8051 with LEDs, 7-segment LEDs, LCD, DC Motor, and ADC will be covered. The program ends with a mini-project that will be designed and implemented completely by the trainees with my guidance. Stress in the entire training would be on the trainees learning to do everything on their own, instead of running existing codes.
Course fees is Rs. 15000/person, inclusive of a 8051 Microcontroller based development board worth Rs. 2000. Details of the hardware kit
Training content and syllabus is available - http://rupamdas.com/docs/EmbeddedSystems-8051-2011.pdf

Posting after a long long time. Hopefully this time the gaps will be lesser.
I had to give a guest lecture to 3rd and final year students of EEE stream in MNM Jain Engineering College on July 3, 2013. Normally I just give a lecture and share my thoughts about Embedded Systems. This time I wanted to show them a demo of a project that evolves from a simple idea to a standalone product, or even a system.
So I decided to take the example of Digital Thermometer based on 8051, which is a simple project for beginners to Embedded System development.
A small project on converting a simple digital thermometer into a wireless temperature sensor node. The temperature sensor is converted into a wireless node by interfacing the MCU's UART to a ZigBee node. The companion ZigBee node is connected to an ARM Cortex M3 based board's UART that receives the temperature data and sends it to the data logger (the laptop here) through another UART port
Here's the demo video of the Wireless Temperature Sensor
This is just a proof of concept. Adding more wireless nodes with additional features can convert this into a wireless network to manage a building or factory or such large areas.
Slides of my lecture on the project prototype are here:

If you are new to Keil uVision IDE, you may have noticed that whether you
use ASM code or C code, the HEX files are not generated when you compile your
programs. This is because Keil does not generate the HEX file by default. In
case you are wondering what HEX file is, HEX file is the output of Keil that is
generated after compilation and linking of your application and this is the file that is 'burned' or programmed into your microcontroller or microprocessor.
So, to enable generation of the HEX file follow these steps:
Step 1) Create the Keil project by adding your ASM and/or C source files
Step 2) Open the project options. Use any of the three methods given below: - Click on Project->Options for Target (Fig. 1)
- Right-click on
the Target 1 in the project window on the left side of the IDE (Fig. 2)
- Simply press ALT-F7 to open the project options:
Step 3) Once the project options window is visible, first click on the
Output tab and then click on the empty check box next to
Create HEX File. The Output tab should look like Fig. 3. Click on
OK and then click on Files->Save All.
Step 4) Now if you build your target, you will see the associated
HEX file in the output directory.
IMPORTANT - You must repeat this process for each new project that you create.
I am planning to offer summer training on the following topics in June-July 2012.
Each training program will end with a mini-project and best projects in a given batch will be showcased in my website.
Certificate of participation will be provided to all those who complete the training successfully
Placement assistance would be provided to those who do exceptionally well in the training and mini-project.
