I'm thinking about buying a few DIP microcontrollers just for fooling around's sake. I think I'll be able to figure most things out except this: how do I send the necessary file (for example, .s19 for freescale mcs) to the microcontroller. In school we have development boards which sort of magically have USB cables which do that part for us. Is there a pin for this on the chip? Will I have to build a USB interface or something?
