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
Simplified schematics

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.

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

RC-04
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.
