[LIS2MDL + STM32F4] SPI Communication OK, but DRDY Flag Stuck Low – No Data Output
I’m working with a LIS2MDL magnetometer sensor connected to an STM32F407VTG6 microcontroller running FreeRTOS. The sensor communicates over the SPI3 interface, and is configured to operate in SPI Mode 0 (CPOL=0, CPHA=0). The chip select (CS) pin is i...
