DDC-SE-01

Description

A sensor development kit for IQRF wireless applications with transceiver modules (TR) plugged in DK-EVAL-04 kit. Compatible with other DDC (Development Daisy Chain) kits.

Ready-to-use examples are available demonstrating how to use I2C and Dallas 1-wire buses and A/D converter inside TR to measure temperature, voltage etc.

Applications

• Development of IQRF applications

• I2C and Dallas 1-wire bus demonstration

• A/D measurement demonstration

Key features

• Compatible with other IQRF DDC kits

• Supplied from DK-EVAL-04

• I2C temperature sensor

• I2C bus connector to access external peripherals

• Dallas 1-wire temperature sensor

• Light intensity measurement using a photoresistor

• Voltage measurement using a potentiometer

• Internal voltage LDO regulator

Hardware

Power supply

DDC-SE-01 should be supplied from DK-EVAL-04 via connector XC2.

Interface connectors

The XC2 male connector with square 0.635 mm, 2.54 mm pitch pins is intended for I/Os and power supply.

Corresponding XC1 female connector serves for interconnection with other DDC kits.

XC3 is a 1.25 mm pitch miniature connector DF13C-5P (Hirose). Mating Hirose cable connector: DF13-5S (plastic shell), DF13 crimp contacts.

Internal peripherals

• I

2

C temperature sensor: MCP9802A3 (Microchip) with fixed I2C

slave address 10010110 (in binary).

• 1-wire temperature sensor: DS1820B20 (Dallas).

• Photoresistor: PGM5539 by Token. Resistance 30-90 kΩ at 10

lux, dark resistance 5 MΩ.

• Potentiometer: The potentiometer is intended for voltage

measurement using the A/D converter inside the MCU on the TR transceiver.

Caution

To enable correct functionality of the pushbutton SW1 on the DK-EVAL-04(A) kit connected, the potentiometer shaft must be in the intermediate position.

External I2C peripheral

• External I

2

C device should be connected via the XC3 connector. It must have I2C slave address different from 10010110

(in binary).

Jumper JP1

• In position 1 – 2 enables 1-wire sensor.

• In position 2 – 3 enables I
