PIC18F87J72 EVALUATION BOARD FUNCTIONALITY AND FEATURES
The PIC18F87J72 Evaluation Board provides a platform for developing and evaluating
applications which are based on the PIC18F87J72 device. These applications can
range from accurate measurement of low signals like an output signal of a load cell to
processing of information for metering and other metrology applications like energy
metering, heatmeter and so on.
The PIC18F87J72 microcontroller has an 8-bit core processor along with many
advanced peripherals like 12-bit SAR-based ADC, two 24-bit delta sigma ADCs and
Charge Time Measurement unit (CTMU) for temperature measurement or
implementation of touch keys.
PIC18F87J72 also has built-in Real Time Clock and Calendar (RTCC) with calibration
registers for time stamping the measured data, and a Liquid Crystal Display (LCD)
driver for a display up to 132 pixels.
The PIC18F87J72 Evaluation Board has the following features to develop and test user
applications:
• Easy connection for low and high voltage signals. Signals from variety of sensors
can be connected to this board.
• Touch keys to select different parameters of the of the 24-bit Delta Sigma ADC,
like Over Sampling Ratio (OSR), Resolution, and Channel gain.
• Direct LCD display, driven from the COM/SEG pins of PIC18F87J72
• Real Time Clock
• Temperature Measurement option with CTMU
The PIC18F87J72 Evaluation Board can be connected to the GUI, supplied along with
the board, to analyze the synchronous sampling, 24-bit, delta sigma ADCs. The ADCs
have 90 dB SINAD and -104dB THD (up to the 35th harmonic) for each channel,
enabling highly accurate energy metering and other low signal level designs. With less
than 10 mVRMS output noise and a programmable gain amplifier of up to 32 V/V, these
24-bit ADCs are capable of interfacing to a large variety of small signal sensors, as well
as voltage and current sensors, including shunts, Current Transformers (CT),
Rogowski coils, Hall Effect sensors and load cells.

The precautions given need to be strictly adhered to, in order to avoid any damage to the evaluation
board and prevent electric shock hazard.
Input high voltage AC signal can be applied between pins 1 and 2 of the connector J4 or J5.
The resistors R26 and R27 should not be populated when pins 1 and 2 of J4 are connected to a high
voltage.
The resistors R28 and R29 should not be populated when pins 1 and 2 of J5 are connected to a high
voltage.
The resistors R26, R27, R28 and R29 can be used only when CT outputs are connected to the
connectors J4 and J5. In this case, these resistors act as a burden resistor to the CT secondary winding.

INTRODUCTION
This chapter provides a brief description on how to use the PIC18F87J72 Evaluation
Board for the measurement and analysis of various signals. It also describes the
process of the demo and explains various configuration changes for observing the
response using the PIC18F87J72 Evaluation Board.
Figure 3-1 shows the PIC18F87J72 Evaluation Board with the 9V supply connected to
the input jack. The initial set up of the evaluation board involves connecting the supply
to the input jack of the board. This provides the required supply to the evaluation board.
Alternatively, the 9V battery can be connected to power the board. In addition, the USB
cable from the computer is connected to the mini USB connector on the board. This is
used for transmitting and receiving data to and from the board, to and from the GUI tool.
The input signal can be connected to connectors J4 and J5. If the microcontroller is
already programmed, then the program will start executing when the supply is turned
on.

PIC18F87J72 Evaluation Board User’s Guide
If the evaluation board is used in programmer mode, then the waveforms and the
response can be observed on the GUI. If the evaluation board is used in debugging
mode, using the MPLAB IDE, then the user can see the response on the Data Monitor
and Control Interface (DMCI) window.
For debugging, the Real ICE/ICD debugger and programmer is connected to the RJ11
connector. After the software is compiled and programmed to the PIC18F87J72 device,
the program can be executed. The LCD display on the board will indicate the time and
the waveforms that can be observed on the GUI window or DMCI. The LCD display on
the board will indicate the time. The various waveforms applied at the input can be
observed on the GUI or DMCI.
Various changes to the device configuration can be done using the touch sensitive keys
S1, S2, S3 and S4. The on-chip CTMU peripheral is used for all the touch-sensitive
keys.
Press the key S1, to change the Over Sampling Ratio (OSR) as shown in Figure 3-1.
There are four OSR configurations that can be created using S1. Each press of the key
S1 will change the configuration of the sigma delta ADC with OSR values from a value
of 256, 128, 64 and 32.
The time from the RTCC can also be displayed using the key S1 as shown in
Figure 3-2.
The RTCC date and time can be set using the following steps:
• Press the keys S2 and S4 simultaneously to enter into the RTCC date setting
mode. The date field on the LCD will start blinking.
• The date can be changed by pressing the key S4 for incrementing and S2 for
decrementing. The key S1 can be used to set the day, month and year fields.
• Press the keys S1 and S2 simultaneously, to enter into the RTCC time setting
mode. The time field on the LCD will start blinking.
• The time can be changed by pressing the key S4 for incrementing and S2 for
decrementing. The key S1 can be used to set the hour, minute and second fields.
By pressing the key S1 repeatedly, the OSR configurations will sequentially change
from 256 to 32 and then back to 256.

Chapter 5. PIC18F87J72 Evaluation Board Lab Test Results
5.1
INTRODUCTION
This chapter provides the various laboratory test results obtained when using the
PIC18F87J72 Evaluation Board. This chapter also describes the use of the Data
Monitor and Control Interface (DMCI) window to plot the waveforms present on
Channel CH0 and CH1 of the evaluation board. Displaying waveforms on the DMCI
window can only be done when the user is working in Debugging mode. In Debugging
mode, the MPLAB IDE needs to be uploaded and the debugger connected to the RJ11
connector of the PIC18F87J72 Evaluation Board.
Figure 5-1 shows two graphs (i.e., Graph 1 and Graph 2). Graph 1 shows the waveform
created on Channel CH0 of the PIC18F87J72 Evaluation Board. Graph 2 shows the
waveform created on Channel CH1 of the PIC18F87J72 Evaluation Board. CH0 and
CH1 are both connected to the same signal of 300 mV. The internal PGA gain is chosen
to be 8 for CH0 and 1 for Channel CH1.

PIC18F87J72 Evaluation Board User’s Guide
Figure 5-2 shows Graph 1 for CH0 and Graph 2 for CH1. The OSR for both CH0 and
CH1 are chosen to be 32 and the signal amplitude applied at the input is a very low
voltage sine wave signal of about 20 mV peak. The user can clearly observe the
distortion of the waveform with such a low OSR value.

PIC18F87J72 Evaluation Board Lab Test Results
Figure 5-3 shows Graph 1 for CH0 and Graph 2 for CH1. The OSR for both CH0 and
CH1 are chosen to be 256 and the same signal is applied at the input with a very low
voltage sine wave signal of about 20 mV peak. Here, the sine wave shape is still
retained and the signal distortion is less when compared to Figure 5-2.

PIC18F87J72 Evaluation Board User’s Guide
Figure 5-4 shows Graph 1 for CH0 and Graph 2 for CH1. CH0 and CH1 are both
connected to the same signal of 300 mV. The internal PGA gain is chosen to be 1 for
CH0 and 32 for Channel CH1. The waveform on Graph 1 is intact, while the waveform
on Graph 2 is saturated at a value of 32768. This demonstrates the effect of saturation
when larger gains are used. This would distort the wave to a flat top waveform, and the
information related to the shape of the signal would be lost.
