Detailed Description

This example is a Heart Rate Monitor (HRM) transmitter simulator. It will transmit the users heart rate information in the main data page (page 4).

Device specific information is transmitted at a slower rate in the background data pages (pages 1-3). It will print out profile state information to UART when data is transmitted out of the device.

HRM specific configuration options

The following compile time configuration options are available to suit various HRM transmitter implementations:

• HRMTX_NETWORK_KEY ANT PLUS network key.
• ANTPLUS_NETWORK_NUMBER Network key associated with the channel.
• HRMTX_ANT_CHANNEL Channel number.
• HRM_DEVICE_NUMBER Device number.
• HRMTX_DEVICE_TYPE Device type.
• HRM_TRANSMISSION_TYPE Transmission type.
• ANTPLUS_RF_FREQ Channel radio frequency offset from 2400 MHz.
• HRMTX_MSG_PERIOD Channel period in 32 kHz counts.

Development phase configuration options

The HRM transmitter simulator will trace out various types of state information to the UART depending on the selected compile time configuration options.

The following compile time configuration options are available to assist in the development phase of the HRM transmitter implementation:

• TX_PAGE1 - output page 1 data to UART.
• TX_PAGE2 - output page 2 data to UART.
• TX_PAGE3 - output page 3 data to UART.
• TRACE_UART - UART output enabled.

Note

The ANT+ Network Key is available for ANT+ Adopters. Please refer to http://thisisant.com to become an ANT+ Adopter and access the key.
