First of all, we want to calculate the range with (DWM3000evb & NucleoF429) boards.
We are trying to follow new documents which is published in Feb 2022, about DWM3000evb for Ranging.
We tried the all ways to connect DecaRanging application and DecaPDOARTLS application with the cards but we couldn’t.
Can you help us! We are college students and we want to calculate ranging.
The correct firmware is loaded on the Nucleo board.
The Slotted TWR demo application should be programmed, which can be found in Software\Slotted_TWR_Demo_ARM\STM32F429_NUCLEO\Bin\twr_demo.hex
See 6 APPENDIX 3 UPGRADING FIRMWARE in the STM QSG (Docs/DW3000_Arduino_Shield_QSG_STM.pdf) for more information.
ensure JP3 is in the “U5V” position
connect the top USB connector to your computer
use your ST-link compatible programmer of choice, e.g STM32 ST-LINK Utility, STM32CubeProgrammer or OpenOCD to load the hex file to the board.
The require hardware modifications to the Nucleo board are made
In order to use both SPI and ethernet, which we use for some applications, all of the Nucleo F429ZI devboards we use at Qorvo UWBU / Decawave have solder bridge modifications that change what pin is used for the MOSI pin.
We also connect E5V to the 5V of the bottom USB connector, allowing the bottom USB connector to power the board.
See section 7 APPENDIX 4 HARDWARE MODIFICATION MADE in the QSG.
To run the latest version of the DW3000 TWR firmware, you will have to make the solder bridge modifications.
The board is powered and USB is connected
By default, we ship modified Nucelo F429ZI boards that are powered from the bottom USB port with the supply selection set to “E5V” on jumper JP3.
If you sourced your own Nucleo board, likely the default supply selection is U5V, which is supplied by the “top” USB connector, which connects to the ST-Link programmer.
You can power the board with the top USB connector and connect the bottom USB connector for data. If you prefer to use a single cable (and prevent near-field effects on the antenna from the cable), you can perform the modifications we document in section 7 APPENDIX 4 HARDWARE MODIFICATION MADE of the QSG.
