- * @file main.c
- * @brief Double-sided two-way ranging (DS TWR) initiator example code
- *
- * This is a simple code example which acts as the initiator in a DS TWR distance measurement exchange. This application sends a "poll"
- * frame (recording the TX time-stamp of the poll), and then waits for a "response" message expected from the "DS TWR responder" example
- * code (companion to this application). When the response is received its RX time-stamp is recorded and we send a "final" message to
- * complete the exchange. The final message contains all the time-stamps recorded by this application, including the calculated/predicted TX
- * time-stamp for the final message itself. The companion "DS TWR responder" example application works out the time-of-flight over-the-air
- * and, thus, the estimated distance between the two devices.

-/*****************************************************************************************************************************************************
- * NOTES:
- *
- * 1. The sum of the values is the TX to RX antenna delay, experimentally determined by a calibration process. Here we use a hard coded typical value
- * but, in a real application, each device should have its own antenna delay properly calibrated to get the best possible precision when performing
- * range measurements.
- * 2. The messages here are similar to those used in the DecaRanging ARM application (shipped with EVK1000 kit). They comply with the IEEE
- * 802.15.4 standard MAC data frame encoding and they are following the ISO/IEC:24730-62:2013 standard. The messages used are:
- * - a poll message sent by the initiator to trigger the ranging exchange.
- * - a response message sent by the responder allowing the initiator to go on with the process
- * - a final message sent by the initiator to complete the exchange and provide all information needed by the responder to compute the
- * time-of-flight (distance) estimate.
- * The first 10 bytes of those frame are common and are composed of the following fields:
- * - byte 0/1: frame control (0x8841 to indicate a data frame using 16-bit addressing).
- * - byte 2: sequence number, incremented for each new frame.
- * - byte 3/4: PAN TAG_ID (0xDECA).
- * - byte 5/6: destination address, see NOTE 3 below.
- * - byte 7/8: source address, see NOTE 3 below.
- * - byte 9: function code (specific values to indicate which message it is in the ranging process).
- * The remaining bytes are specific to each message as follows:
- * Poll message:
- * - no more data
- * Response message:
- * - byte 10: activity code (0x02 to tell the initiator to go on with the ranging exchange).
- * - byte 11/12: activity parameter, not used here for activity code 0x02.
- * Final message:
- * - byte 10 -> 13: poll message transmission timestamp.
- * - byte 14 -> 17: response message reception timestamp.
- * - byte 18 -> 21: final message transmission timestamp.
- * All messages end with a 2-byte checksum automatically set by DW1000.
- * 3. Source and destination addresses are hard coded constants in this example to keep it simple but for a real product every device should have a
- * unique TAG_ID. Here, 16-bit addressing is used to keep the messages as short as possible but, in an actual application, this should be done only
- * after an exchange of specific messages used to define those short addresses for each device participating to the ranging exchange.
- * 4. Delays between frames have been chosen here to ensure proper synchronisation of transmission and reception of the frames between the initiator
- * and the responder and to ensure a correct accuracy of the computed distance. The user is referred to DecaRanging ARM Source Code Guide for more
- * details about the timings involved in the ranging process.
- * 5. This timeout is for complete reception of a frame, i.e. timeout duration must take into account the length of the expected frame. Here the value
- * is arbitrary but chosen large enough to make sure that there is enough time to receive the complete response frame sent by the responder at the
- * 110k data rate used (around 3 ms).
- * 6. In a real application, for optimum performance within regulatory limits, it may be necessary to set TX pulse bandwidth and TX power, (using
- * the dwt_configuretxrf API call) to per device calibrated values saved in the target system or the DW1000 OTP memory.
- * 7. dwt_writetxdata() takes the full size of the message as a parameter but only copies (size - 2) bytes as the check-sum at the end of the frame is
- * automatically appended by the DW1000. This means that our variable could be two bytes shorter without losing any data (but the sizeof would not
- * work anymore then as we would still have to indicate the full length of the frame to dwt_writetxdata()). It is also to be noted that, when using
- * delayed send, the time set for transmission must be far enough in the future so that the DW1000 IC has the time to process and start the
- * transmission of the frame at the wanted time. If the transmission command is issued too late compared to when the frame is supposed to be sent,
- * this is indicated by an error code returned by dwt_starttx() API call. Here it is not tested, as the values of the delays between frames have
- * been carefully defined to avoid this situation.
- * 8. We use polled mode of operation here to keep the example as simple as possible but all status events can be used to generate interrupts. Please
- * refer to DW1000 User Manual for more details on "interrupts". It is also to be noted that STATUS register is 5 bytes long but, as the event we
- * use are all in the first bytes of the register, we can use the simple dwt_read32bitreg() API call to access it instead of reading the whole 5
- * bytes.
- * 9. As we want to send final TX timestamp in the final message, we have to compute it in advance instead of relying on the reading of DW1000
- * register. Timestamps and delayed transmission time are both expressed in device time units so we just have to add the desired response delay to
- * response RX timestamp to get final transmission time. The delayed transmission time resolution is 512 device time units which means that the
- * lower 9 bits of the obtained value must be zeroed. This also allows to encode the 40-bit value in a 32-bit words by shifting the all-zero lower
- * 8 bits.
- * 10. In this operation, the high order byte of each 40-bit timestamps is discarded. This is acceptable as those time-stamps are not separated by
- * more than 2**32 device time units (which is around 67 ms) which means that the calculation of the round-trip delays (needed in the
- * time-of-flight computation) can be handled by a 32-bit subtraction.
- * 11. The user is referred to DecaRanging ARM application (distributed with EVK1000 product) for additional practical example of usage, and to the
- * DW1000 API Guide for more details on the DW1000 driver functions.
