DW1000 SPI Frequency


We are using STM32F205 micro-controller for interfacing with DW1000. This have maximum spi frequency (SPI2) of 15MHz that we can set. But Decawave can support up to 20MHz. If we use 15MHz, how does it will affect the two ranging performance?

This will be just fine! Faster SPI speeds can useful for debugging, reading back the CIR data at fast update rates. Also note for example, the NRF52832 SPI on the DWM1001 is only 8MHz
