8/29/2023 0 Comments How to program pic12f629This is the chip we introduced in the previous article. A 19 byte difference in microcontroller programming is already significant! Our First PIC Assembly Language CodeĪs an introduction to PIC assembly programming, we'll be using PIC16F84A, a x14 architecture microcontroller by Microchip. MAIN_PROG CODE let linker place main program RES_VECT CODE 0x0000 processor reset vector Now take this PIC assembly code which does the same thing as the code above: TODO INSERT CONFIG CODE HERE USING CONFIG BITS GENERATOR This code when compiled and assembled generates a 182-byte hex file. _delay_ms(65) //65 millisecond delay between In microcontroller programming, saving program space is essential as you only have a few to work on. Take this simple LED blink program written in XC8, for example: #define _XTAL_FREQ 4000000 //4 MHz crystal High-level languages often have additional headers that take up program memory space.
