RC-04

Description

RC-04 is a universal user programmable IQRF remote controller with bidirectional communication.

It is a generic equipment, i.e. the hardware is fixed and the user can realize specific functionality by software for internal microcontroller. This can be uploaded by the user via RF (which is the only way how to upload the code into the device).

Applications

• Portable controller

• Automation

• Voting systems

• Wide usage facilities

Key features

• Built-in IQRF transceiver module

• Programmable via RF only

• Architecture based on TR-52, FSK

• On-board PCB antenna

• 4 pushbuttons, 2 LEDs

• Bidirectional communication – high security in comparison to unidirectional systems

• High performance

• Sleep mode with ultra low power consumption

• Coin battery

• Low cost

Electrical specifications (typical values unless otherwise stated)

RF transceiver built-in, based on the TR-52B architecture

RF IC MRF49XA (Microchip)

Microcontroller PIC16F886 (Microchip) Antenna PCB shortened ¼ wave whip Frequency band 868 MHz or 916 MHz, multiple channels (SW selectable) RF output power up to 3.5 mW, programmable in 7 steps

Battery Lithium 3V, 210 mAh coin cell CR2032

Supply current depends on application SW (see TR-52B datasheet for details)

Sleep mode 0.8 µA (all peripherals shut down)

Additional watchdog supply current 2 µA typ., 4 µA max. (watchdog enabled)

Run mode 1 mA @ 8 MHz (RF circuitry in standby mode)

Additional supply current 0.6 mA (RF circuitry on)

2 mA (one or two LEDs on)

Rx mode

STD mode 13 mA LP mode 3.5 mA (depends on interferences) XLP mode 600 µA max. (depends on interferences)

Tx mode 14 mA – 24 mA (according to RF output power)

Temperature range 0 °C to +70 °C

Dimensions 58 mm x 42 mm x 14 mm Weight: 29 g (with the battery and the charm chain)

Absolute maximum ratings

Stresses above those values may cause permanent damage to the device. Exposure to maximum rating conditions for extended periods may affect device reliability.

Supply voltage (VCC): 3.5 V Storage temperature: -40 °C to +85 °C

Hardware

RC-04 is a generic equipment, i.e. the hardware is fixed and the user can realize specific functionality by software for integrated transceiver module only.

Power supply

RC-04 is supplied from the coin non-rechargable battery.

Sleep mode

It is possible to switch off all functions and peripherals to minimize current. For Sleep mode control refer to demo software included. The power can not be switched off at all (unless removing the battery), the Sleep mode is used instead of this.

Tip: User SW should allow wake-up the controller after pushbutton(s) press. See demo SW included.

Pushbuttons and LEDs

Functionality of all four pushbuttons and both LEDs is fully under user software control.

RF transceiver

Integrated IQRF wireless transceiver based on the TR-5xB architecture. User SW uploading is possible via IQRF wireless upload only (without opening the case).

Antenna

Built-in PCB antenna on the RC-04 board.

Software

Demo application

This demo illustrates unidirectional non-networking communication between the RC-04 controller and the CK-USB-04 kit equipped with the TR-52B module connected to PC with the IQRF IDE Terminal running. The RC04_simple.c program is intended for the controller and the E02-RX (one of basic IQRF examples) for the TR module in the CK kit. Both are available on IQRF CD and IQRF website. To upload the RC04_simple.hex to the RC-04 via RF – see Application note AN009 – IQRF wireless upload. Switching to RF PGM mode after reset is enabled by default.

In idle state the controller stays in Sleep mode allowing wake-up by any pushbutton. After wake-up the battery voltage is checked and LEDs flashing indicates pressing the button and accumulator condition. Then respective command is sent to CK-USB-04 and the controller gets to sleep again.

Buttons Function

• S1 text sent: "S1x" x=0 if battery O.K. otherwise x=1

• S2 text sent: "S2x" -"-

• S3 text sent: "S3x" -"-

• S4 text sent: "S4x" -"-

• S3 + S4 for more than 5 s enter RF PGM mode

• S2 for more than 0.7 s leave RF PGM mode

LED indication

• button S1 to S4 1 x flash green (battery O.K.) / red (battery exhausted).

• RF PGM indication See the Application note AN009 – IQRF wireless upload.

Caution: Select the proper version of Demo according to IQRF OS version (2.11 or 3.xx) implemented in RC-04.

To distinguish OS version, catch Module Info which is always sent by this Demo application just before switching to RF PGM mode in IQRF IDE Terminal. Show hexa checkbox should be checked. OS version is in buffer

moduleINFO[4]. See the picture above and IQRF OS User's guide.

Example:

moduleINFO[0–7]: [0] [1] [2] [3] [4] [5] [6] [7] 3C 5D 00 01 30 03 39 11

moduleINFO[4] = 30 means OS v3.00 moduleINFO[4] = 2B means OS v2.11

Caution!

The only way how to upload user application into the RC-04 is RF PGM (wireless programming, ICWP). Demo application RC04_simple.c invokes the enableRFPGM function first. It ensures that after every reset (due to reconnecting the battery) the device is switched to RF PGM mode and can possibly be reprogrammed. This feature can be removed (by disableRFPGM), but it should not be done unless there is another reliable way how to invoke back the RF PGM mode using runRFPGM after pressing a pushbutton. See the demo application, refer to AN009 Application note for details. If being omitted the device can not be reprogrammed any more. Recovery is possible by the manufacturer only.

Tip: Always use enableRFPGM during development.
