Massive Open Online Courses ( Transforming education )
Jayaraman Kiruthi Vasan outlines why MOOCs have become a practical way for embedded engineers and programmers to learn from top universities without quitting jobs. The post highlights platform options like Coursera, edX, Udacity and Khan Academy, explains how on-demand video lectures and clear prerequisites make targeted upskilling feasible, and points to DSP and Python courses useful for embedded design.
Get your microcontroller and PC to talk
Projects often need a quick PC interface for an otherwise standalone microcontroller, but learning VB or Visual C++ can feel like overkill. Jayaraman Kiruthi Vasan shows how Processing, an open source, C like environment with serial and Arduino libraries, gives embedded engineers a fast, low friction way to build GUIs and COM links to chips like the 8051 and Renesas R8C. The post promises a hands on example connecting Processing to a 8051.
Embedded - Where to start and how to continue?
When the whole world is talking the magic words 'Embedded' and 'Microcontrollers', there definitely are a whole bunch of engineers who are more into hardware and have the eternal hesitation on how to plunge into the embedded world.
These folks are good in hardware, very analytical in their approach and have all the ingredients to become experts in this part of the geek world.
Good old multiplexed keypad in an embedded system
Multiplexed keypads remain the most practical input for mid-budget embedded projects, especially where hard-wired keys survive harsh environments and rough usage. Jayaraman lays out a simple, reusable approach by splitting key handling into three tiny modules: a GlanceKey quick check, on-demand Decode, and a compact state machine. The pattern cuts CPU time, runs from a timer, and boosts portability across MCUs.
