1. Embedded Wifi Bare-Metal Development From Ground Up™
Connect Your Embedded Device to the Internet : STM32, Web Server, Web Client, Cloud Storage etc.
14 hours | Complete source code included
Welcome to the Embedded WIFI Bare-Metal Development From Ground Up™ course.
This course teaches you how to develop drivers and libraries for connecting your embedded device to the internet.
This course uses the STM32 microcontroller and the ESP8266 WIFI chip. The ESP8266 is a low-cost WIFI chip with a full TCP/IP stack and a microcontroller. If you do not understand what TCP/IP stack means, do not worry, by the end of this course you will understand this and much more.
The course can be divided into four parts. The first part is theoretical. In this part we shall learn about some networking concepts and the fundamentals of the WIFI protocol.
In the next part of the course we shall develop bare-metal drivers for interfacing the ESP8266 chip to the STM32 microcontroller.
After developing our drivers for connecting the ESP8266 chip to the STM32 microcontroller we shall then go ahead and develop efficient data structures for managing communication data between the ESP8266 chip and the STM32 microcontroller.
In the final part we shall combine the drivers and data structures developed in the previous parts to develop a library for connecting to the internet. We shall then go on to use the library to develop a WebServer, a Web Client as well as accomplish tasks such as storing sensor data in the cloud and so much more.
Please take a look at the full course curriculum.

2. Embedded Systems Cellular Firmware Development(GSM)
Communicate with your embedded devices using cellular technology : Phone Call, SMS, M2M etc.
10+ hours | Complete Source Code Included
This course teaches you how to develop drivers and libraries for adding cellular functionality to your embedded device.
This course uses the STM32 microcontroller and the A6 GSM/GPRS chip. The A6 is a low-cost quad band GSM/GPRS chip equipped with 850/900/1800/1900MHz worldwide communication band.
