What is the role of the microcontroller placed on the programmer.

[Saioa]

Most of the programmers have a microcontroller placed on them. What does it do?

Hi Saioa

You can consider them as embedded applications made for burnig source code inside other chips. These are also programmed in a simialr way as you program any ordinary microcontroller for an embedded application. They simply communicate with computer, using their USART terminals, and then burn the hex file (a source code) into other microcontrollers.

Hope this helps

u need a mediator between host device (your micro controller for application) and your PC/laptop. it sets up the protocol between these two devices and downloads HEX file from PC into internal FLASH of your micro controller
