Many people have hesitated making this move because they are not sure exactly what changes need to be made in order for the 628 to respond like an F84. As when moving to any new chip, make sure that the necessary changes are made inside MPLAB or whatever compiler you are using. Also check your config. bits when programming so the correct Oscillator is selected. The following code will flash an LED once each second for a duration of 1/2 second. I hope this supplies everyone with a takeoff point to start using the more versatile 16F628. Cut and paste this into your compiler. Be sure to set your configuration bits when programming the following: ***** CODE BEGINS CUT HERE ***** LIST P=16F628 ; LIST DIRECTIVE TO DEFINE PROCESSOR #INCLUDE <P16F628.INC> ; PROCESSOR SPECIFIC VARIABLE DEFINITIONS ;__CONFIG B'11110100000010' ;__CONFIG _CP_OFF & _WDT_OFF & _BODEN_OFF & _PWRTE_ON & _ER_OSC_CLKOUT ; & _MCLRE_ON & _LVP_OFF ; '__CONFIG' DIRECTIVE IS USED TO EMBED CONFIGURATION DATA WITHIN .ASM FILE. ; THE LABLES FOLLOWING THE DIRECTIVE ARE LOCATED IN THE RESPECTIVE .INC FILE. ; SEE RESPECTIVE DATA SHEET FOR ADDITIONAL INFORMATION ON CONFIGURATION WORD. ;**************************************************************************** ;***** VARIABLE DEFINITIONS W_TEMP EQU 0X28 STATUS_TEMP EQU 0X29 COUNTERA EQU 0X2A COUNTERB EQU 0X2B COUNTERC EQU 0X27 ;**************************************************************************** SETUP BSF STATUS,5 ;BANK SWITCH TO BANK 1 MOVLW B'00011111' ;SETS PORTA TO INPUTS MOVWF TRISA MOVLW B'00000000' ;SETS PORTB TO OUTPUTS MOVWF TRISB MOVLW B'01000010' MOVWF OPTION_REG MOVLW B'00000111' ;THIS HAS TO BE DONE IN ORDER TO USE MOVWF CMCON ;PORTA AS YOU WOULD AN F84 ;THIS TURNS OFF THE CAPTURE ;AND COMPARE ; THE FOLLOWING INSTRUCTIONS CLEAR THE CALLED REGISTERS BEFORE USING THEM. ;I HIGHLY RECOMMEND THIS ; ALWAYS CLEAR YOUR PORTA AND PORTB REGISTER ;SO YOU KNOW THEY ARE CLEAR BEFORE USING THEM!!!!!!!!!
