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.
