Hi,
I have a PCB with the BMP388 and I am trying to communicate with the sensor from an STM32F722 via SPI.
This is the schematic:
This is the SPI configuration in STM32CubeIDE:
When trying to communicate with the sensor via SPI, I receive the wrong chip id (0x22 and 0x0F, depending on the SPI configuration).
Also, the sensor never enters normal mode and the data ready interrupt never fires.
I am using the BMP3-SensorAPI (https://github.com/boschsensortec/BMP3_SensorAPI)
in combination with the STM32 example code posted here: /mems-sensors-forum-jrmujtaw/post/how-to-adapt-bosch-sensor-api-s-to-use-with-stm32-FyBtiUfyFQ9NAR8?highlight=9CWaQoH6wdYv8Cv
Unfortunately, I don't have an oscilloscope to test the SPI signal.
Any help is appreciated.
