Device Programmers for PIC Microcontrollers
Once the program is written and translated into executable code, the resulting HEX file is loaded to the target microcontroller’s program memory with the aid of a device programmer. The type of device programmer depends on the type microcontroller to be programmed. For instance, some device programmers can only program PIC16 series, whereas some can…
