IQRF chat
A demonstration of wireless communication via sending and receiving chat messages. An IQRF packet is considered to be
a chat message if contains the identification.
•Transmitting: A user string can be entered from the keyboard (allowing user predefined symbols) to the Tx field and sent
by the TR module as an RF chat message by pressing the Send button.
•Receiving: Embedded TR module continually listens to incoming RF packets. If a correct chat message is detected, the
received text is displayed in the Rx field.
This demo works if the tr_vcp04 application is uploaded in the embedded TR module.
Temp sensor
A demonstration of wireless communication via receiving messages from external TR module measuring temperature and
battery level. This demo works if the vcp_temp_sensor application is uploaded in remote TR module.
Embedded TR module continually listens to incoming RF packets. If a correct message is detected, the received values are
displayed on the screen.
Infrared module
A demo example of a remote IR controller utilizing the communication protocol defined by Sharp. Whenever the button is
pressed the predefined message is sent. If the button is held pressed the message is sent repeatedly until the button is
released. To control the volume, the touch scrollbar located in bottom part of the device
is intended. The volume is proportional to the position on the scrollbar. Only sending
feature is currently supported by IR module.
RGB editor
A useful tool for selection of colors. Select one from the three RGB primary colors. The
buttons display their levels. Current color can be set by selecting particular color field
and then by using the touch scrollbar. The resulting color is displayed also as a numeric
code.
Audio
A demo for audio operation. Audio files should be placed in the SOUNDS folder on the SD card. This demo supports also
playing an audio file from internal Flash memory of main MCU. Due to space saving, it is recommended just for a short
audio track. Audio library supports WAV files without compression. VCP-04 allows to play audio samples with rates from 8
kHz to 48 kHz and from 8 to 32 bit resolution. The golden mean 32 kHz sample rate and 16 bit resolution is recommended
as optimal.
Basic control for OPE , PLAY, STOP and a Volume setting is implemented. The volume is set by touching the scrollbar
located at the bottom part of the device. The short sound track played immediately after pressing the PLAY button
demonstrates the capability of reading and playing audio data from internal Flash memory.
Sleep
It allows to put the device in sleep (standby) mode. This screen can be also accessed by holding the user button pressed
not longer than 2 s. Device can be woken up upon pressing user button or connecting external power source.
Vibro module
It demonstrates the capability of vibration module. Single-shot and repeated vibrations are supported.
SD card
A demo for initialization of the SD card and test access to the card by reading and writing a text message to the file.
GW_FILE.t t is used for reading and writing tests.
The SD card connector is equipped with a contact to detect whether the card is inserted. This contact is checked and the
following message is issued:
• Contact: Error – the contact is open
• Contact: OK – the contact is switched
If no SD card is inserted the message „SD card not inserted“ is issued.
