Programming a microcontroller in assembly languages takes time and to reduce that time, embedded systems engineers often have tricks up their sleeves. One of those tricks is the use of lookup tables. In this post, I will share how I use lookup tables in assembly language for PIC microcontrollers. The RETLW Opcode Lookup tables are […]

We write the position of a member of our table in W register, and using CALL instruction we call a subprogram which creates the table. First subprogram line ADDWF PCL, f adds the position of a W register member to the starting address of our table, found in PCL register, and so we get the real data address in program memory. The bare necessity for PIC 16C84 & 16F84 Microchip microcontrollers. Basics information for beginners including: What is PIC?, Features, Design, Memory Arrangement, Video tutorials.

I am doing an alarm system project based on a pic16f84 microcontroller controlling a GSM mobile phone Nokia 5110/6110. I have written a code to do the MSGTABLE ADDWF PCL, f ; offset added to PCL RETLW 0x48 The low bytecomes from the PCL register, which is a readable andwritable register. The high byte (PC<12:8>) is not directlyreadable or writable and comes from PCLATH. On anyReset, the PC is cleared.

The problem with addwf PCL,F is that once you do it, you are gone and can't propagate any carry (from spanning

and introduce a couple of instructions along the way. I am going to set up Port A as per the example above. First, we need to switch from Bank 0 to Bank 1. We do this by setting the STATUS register, which is at address 03h, bit 5 to 1. BSF 03h,5 The BSF Means Bit Set F. The letter F means that we are going to use a memory location, or register.

Basics information for beginners including: What is PIC?, Features, Design, Memory Arrangement, Video tutorials. 15-4-2002В В· The PIC microcontrollers have a paged instruction address space. This has implications for instructions like call, goto, and addwf PCL,F, which modify the program counter. My simulation has no awareness of paged memory restrictions. I couldn't think of a way to model this in the simulation.
