Robotics/Computer Control/The Interface/Microcontrollers

Microcontrollers are low level devices and it is common to program them using an assembly language, this provides a great deal of control over the hardware connected to the controller.

microcontroller is a kind of microprocessor, because it includes a CPU, but it typically also contains all of the following components on the same single chip:

If you wanted to change that software, you would have to pull out the ROM chip, program a new ROM chip (in a 'chip programmer'), and then plug the new chip into the PC.

They can be rewritten with new data, like a memory chip, but permanently, and only a certain number of times (10,000 to 100,000 erase/write cycles).
