State of Embedded Programming

I am engineer with a love of solving problems using both the hardware and software sides where required. Been playing with computers & micro controllers for almost a decade …

I have been playing with microcontrollers for over a decade and have developed normal desktop and web applications too. When I started playing with microcontroller I had many questions like

  • If I have to do so much of coding to get just one LED to light up on this tiny hardware then why is it so easy to get a entire string printed on monitor in my desktop application ?
  • What is happening under the hood of printf function? because when I connect simple character lcd to my 8 bit microcontroller I have to write entire driver to print simple character on it.
