This free online course on the Architecture and Physical Interfacing of Embedded Systems introduces you to the features and working principles of the MSP430 microcontrollers. The MSP430 is a mixed-signal microcontroller from Texas Instruments which was initially introduced in Europe in 1993 and the rest of the world in 1997. MSP is an abbreviation for Mixed Signal Processor and this is to indicate that the microcontroller has a CPU, another digital building block, and also has support for analog circuits. The MSP430 has more than 500 different microcontrollers and this varies from the capabilities, kind of hardware support, amount of memory, physical footprint, small chip, big chip, etc. The two most important features of the MSP43062x53 will be explained in this course. You will learn how to operate an MSP430 circuit with the help of a lemon battery. The battery is made out of lemons and two electrodes made out of copper and zinc. You will experiment with 4 batteries each battery producing 0.9 volts. So, roughly the voltage is 3.6 volts, which is suitable for powering an MSP430 circuit.

Next, you will study the MSP430 series memory architecture and map with a focus on the G2553 microcontroller. The RAM of this microcontroller, which stores variables as well as stacks on the G255 series will also be analyzed. You will discover the 16 registers of the CPU of the MSP430 with emphasis on 4 special purpose registers, which include: Program Counter, Stack Pointer, Status Register, and Constant Generator. You will also consider the various ways of programming the MSP430 and how to write programs and download them in the memory of the evaluation kit of the MSP430 lunchbox. Additionally, you will consider how to interpret warning messages, editing and fixing errors after writing and downloading programs onto the lunchbox. In this section, 3 options will be considered. The Spy -Bi-Wire, JTG Debugger, and UART/USB Bootloader mechanisms. You will be shown the physical interfacing of the MSP430 microcontroller, as well as the various input and output devices associated with the device. The ways in which a user can interact and provide input to the microcontroller will also be highlighted.

Finally, the 2 kinds of input devices, the human inputs, and environment inputs will be reviewed. You will be taught how to connect the various switches to the microcontroller as well as handle a large number of switches. The LED concept, controls, and increases in the current will be explained. You will also learn how to connect LEDs in various ways. The RGB LED and the 7 segment displays of the LED will be discussed. Also, you will study the various ways of driving LEDs in 2 modes called Low Side Driving and High Side Driving. Learning about the MSP430 microcontroller will give you skills and expertise to design, manufacture and manage these devices. This online course is unique and has a hands-on approach for learning to operate a significant hardware component. So, why wait? start this course today.
