Tired of putting LEDs every time you want to check some value in the microcontroller? Well, its time to build yourself a debugger.
A debugger is a device which helps you run through your code in the microcontroller step by step and also gives you the ability to read or write the registers directly using the PC which means you can check the value of any register or any variable at any time without the need for any external components like LEDs or seven segment displays. A debugger will help you immensely when you’re in the prototyping phase of any project. Since I almost entirely use AVR, I’ll be showing you how to build an AVR debugger. (more…)
