Hi Leo,
Sorry for the delay.
This topic solved my problem:

Call dwt_softreset ， then can‘t read ID

[image] so the SPI acceptance driver function of STM32F103 can not be used directly on stm32l432kc, it needs to be modified before it can be used. After modification, test with 20 bytes of data, send and receive successfully. And after dw1000 is initialized, SPI signal will also improve. [image] The modified code CS signal jitter also disappeared. Modified code: int readfromspi(uint16_t headerLength, con…
