PLC and microprocessors

 Weight Sensor Signal Conditioning (20%)
You should provide a detailed description including circuit diagrams and relevant design calculations
explaining how the two weight sensors will be interfaced with the PIC18F4455 microcontroller. You
should explain the rationale for the design and how it is makes optimal use of the available feature
of the microcontroller. You should identify suitable weight sensor and provide relevant calculations
and data.  
Weight Control System Design Notes (10%)
You will carry out design work on the code and produce a set of design notes which may include:
• a flow chart of the operation of the program,  
• a list of the I/O pin allocations
• A list of the subroutines you will use.  
• Pseudocode outline for your program
Microcontroller Code (20%)
You  should  provide  PIC18F2455  code  to  implement  the  required  functionality.  All  code  should  be
appropriately commented and presented in a professional fashion using appropriate formatting and
indentation.  You  may  write  the  program  in  Assembly  Language  OR  C  code  suitable  for  the  XC8
compiler.
