source and the output voltage is scaled using a differential
amplifier. The output is then connected to a 12-bit
differential Analog-to-Digital Converter (ADC) MCP3301. The
ADC outputs serial data to a PIC18F2550 device using a
Serial Peripheral Interface (SPI). The data is transmitted to a
PC using a USB interface. A Microsoft Excel® macro is used
as a Graphical User Interface (GUI) to acquire the data. The
acquired data is stored in an Excel worksheet and graphed
as a real-time strip chart display.

using the PICkit™ 1 Flash Starter Kit and transfers the
temperature readings from the EEPROM to the PC. Microsoft

EATURED
The MCP9700 Thermistor Demo Board contains
the analog circuitry to measure temperature. The
board uses BC Components’ 232264055103
NTC thermistor to convert temperature to
resistance. The thermistor is placed in a voltage
divider which converts resistance to voltage. This
voltage is filtered and placed at the MCP6S22
Programmable Gain Amplifier’s (PGA) CH0 input.
The MCP3909/PIC18F85J90 Single Phase
Energy Meter Reference Design is a fully
function single phase meter. The design is
intended to be low cost and is transformerless.
The design uses a half-wave rectified power
supply circuit and a shunt current sensing
element. A single MCP3909 acts as the

MCP73831 (single cell Li-Ion/Li-Polymer Charger) and
PIC18F4550 MCU. The board measures: (1) the battery
voltage and (2) the current coming out from the battery in
the discharging mode and into the battery in the charging
mode using the ADC device (if charging mode is enabled
(optional)). It calculates the total fuel used and also fuel
remaining.
