flowchart and Assembly code
-
Hi I need some help with a project i'm doing; There are 8 stations in a plant that have 3 parameters (voltage, current, and temp.) that must be kept within certain limits. provide system monitoring and check for defective equip. REQ: each station must be monitored every 4 or 5 seconds for changes in any of these values. (Note to start these values will be available in a block of memory starting at address DATA. Data Format: 1st byte station number 01-08 hex, 2nd byte Voltage reading 00-99 hex, 3rd byte Current reading 00-99 hex, 4th byte Temp. Reading 00-99 hex. Before the 8 sets of values for DATA can be used, they must be transferred from another location in memory labeled INPUTS. Therefore, part of your task will be to move the values in INPUTS locations to the DATA locations. The voltage, current, and temp. Values determined at that time are to be checked against an upper and a lower limit. Values for the upper and lower limits for voltage, current and temp for all 8 stations will be available in a block of memory starting at address LIMITS in the format listed below. LIMITS Format: 1st byte Voltage Upper limit 00-99 hex, 2nd byte Voltage Lower limit 00-99 hex, 3rd byte Current Upper limit 00-99 hex, 4th byte Current lower limit 00-99 hex. 5th byte Temp Upper limit 00-99 hex, 6th byte Temp Lower limit 00-99 hex. What I need: 1. Is a flowchart of the program matching the operation of the program. 2. A printout of the assembly language source program with comments on each line of code, main program header, and subroutine headers. We are using the Motorola 68HC11 EVBU boards :confused:

How 'bout you show us what you've already done, explain what problems you're having, and then ask specific questions? Sounds like a challenging lab/homework assignment. We did something similar in my mcontrollers class - a digital voltmeter. Oh, and though you might find some HC11 hobbyists and/or experts here, I'm sure there are many other sites that can offer you more directed help. This is a Windows programming site. :) Just Google for 68HC11 and you will be inundated with information. Jon Sagara What about :bob:? Sonork ID: 100.9999 jonsagara
