    It creates C-code firmware projects based on the AX-ConfigurationUtilityAPIManual (described in DOCU/ AX-ConfigurationUtilityAPIManual.pdf), which demonstrate the use of the AX5043 transceiver together with the AXM0F343 SoC for packet transmission and reception in several modes. Using the simple GUI, the transmitter (MASTER) and receiver (SLAVE) can be easily configured into the desired mode.

  • Page 4: Installation

    • To verify and validate SoC AXM0F343, compiler such as ARM GCC (Version 5.0 and above) is required to be installed. AX-ConfigurationUtility is included as a standalone installer. Please uninstall any previously installed versions of this software before starting a new installation.

    RSSI threshold has to be set several dB above sensitivity limit prevent false positives. The RX proceeds to scanning for preamble if RSSI > absolute threshold AND RSSI >= (background RSSI + relative threshold). Background RSSI is the RSSI average over past wake ups. www.onsemi.com...
  • Page 14 Thus, while the RX wakes up periodically, actual packet reception is the exception in this mode, occurring only e.g. if a remote-control button was pressed. This is in contrast to the Synchronized with TX mode; in which a packet is expected each time the RX wakes up. www.onsemi.com...

  • Page 15: Rx Synchronized With Tx Mode

    The Sync Timing button opens the Sync Timing panel, where various timing parameters can be configured. This contrasts with the asynchronous nature of Wake on Radio mode, where a preamble is at least as long as the RX sleep interval is required. www.onsemi.com...

The terminal settings should be configured to set baud rate = 115200, stop = 1, parity none, data = 8 bits.

  • Page 24: Framing Panel

    AX-ConfigurationUtility User Manual 8. Framing Panel Figure 6: Framing panel for AXM0F343 Framing mode: Options are HDLC, Raw Pattern Match and PN9 Compatibility. In Raw Pattern Match mode an arbitrary SYNC WORD of up to 32 bit marks the beginning of a frame. For legacy systems the PN9 Compatibility mode implements PN9 data whitening in software, based on the AX5043’s Raw Pattern Match mode.
  • Page 25 Bypassing the encoder is achieved by setting the UNENC flag corresponding FIFO DATA chunk. This causes the chunk data to bypass manchester, scrambler and differential encoder, however inversion still applies. For convenience AX-ConfigurationUtility therefore inverts preamble and SYNC WORD bytes before writing them to the firmware code if “unencoded” and INV encoding are selected. www.onsemi.com...
  • Page 26 The reason for this is, that the byte and nibble order of a SYNC WORD written left to right but read LSB first can be confusing.) • “CRC SKIP FIRST” causes the first byte of the packet to be excluded from CRC calculation. • Select CRC algorithm and initial value. www.onsemi.com...
  • Page 27 Packet Match mode, the RX strips the CRC bytes unless you manually set bit 5 in radio specific PKTSTOREFLAGS register. example: AX5043_ PKTSTOREFLAGS. • Packets with incorrect CRC are silently dropped unless you manually set bit 2 in the Radio specific PKTACCEPTFLAGS register.
