Hello,
I’ve been looking through the available documentation but can’t find information on which nRF52832 pins are used for SPI communication with DW1000 and which for I2C for accelerometer. I am experimenting with already existing firmware for nRF52832 + DWM1000 and trying to run it on DWM1001 but without this information it’s more difficult. I would greatly appreciate if somebody could help me with figuring this out or pointing to correct documentation.
Hey,
Check out https://www.decawave.com/dwm1001-documents-source-code-android-application-firmware-image - Inside there is a schematic of the DWM1001 module, and you can see what the pin connections are. Specifically in the file “DWM1001_module_schematics_vd1.pdf”
SPI1_MISO: P0.18
SPI1_MOSI: P0.20
SPI1_CLK: P0.16
DW_IRQ: P0.19
DW_CS: P0.17
DW_RST: P0.24
SDA: P0.29
SCL: P0.28
Hi guys,
I’ve attached the complete table. DWM1001 datasheet should be updated this week with the information.
Thanks
Yves
Thank you for your answers. Eventually I found this thread https://www.decawave.com/decaforum/showthread.php?tid=460 which links to interesting documents, including one which answered the question
Hi!
I’ve been reading the schematics but I don’t find where are connected some pins.
For instance, P0.02, P0.04, P0.04 are connected to the label J6,J7 and J8 but they are never used,
Are they accessible ? They don’t appear in the pinout of the module
