Peter says that &quot;This is too good to miss, although it's probably not for the faint hearted. Of course it's easier to do the whole lot as a 256 byte look-up table, but this was not really an option until PICs came with larger memories&quot;.<BR>

Hi, I am trying to make an interface between a 16F877 and the EEPROM 24LC65. Does anyone has assembly routines for this interface? Moreover, does anyone can show me how am I going to connect 16F877 in order to write and read from EEPROM 24LC65???<BR>

Simulpic 2.0 is a PIC 16F84 Simulator.<BR>
<BR>
it is free and open-sourced and is a part of the GNU Debian Linux. the significance of Simulpic lies in its simplicity: the system is easy to understand, use and modify. i built a distributed embedded system simulator that is composed of thousands of 16F84's and i found Simulpic to be amenable to hacking. you might find it useful as a stand-alone simulator and/or as a building block for more complex systems.<BR>

Hi<BR>
<BR>
I am a little confused by Microchip Appln Note AN556 on Page 3, where the Example 5 code segment implements a 13-bit computed GOTO. <BR>
<BR>
After using this code segment, I see that my CALL to TABLE offsets by the wrong amount. I cant imagine that the code in the Application Note can be wrong, so what could I be doing wrong?<BR>
<BR>
kind regards<BR>
Manoj<BR>
