Hello community, I'm trying to hook up a BMI323 with my CC1311 eval board from TI. The devices are connected via SPI. When I read out the Chip ID by sending two bytes (0x80 and 0x00) I get 0x00 (without external pull-ups) or 0xFF (with external pull-ups) as response which is wrong. After connecting my Oscilloscope I realised that the MISO signal from the BMI323 barely changes the voltage levels. I tried with and without external 10kOhms pull up resistors but that didn't help. Here are the measured signals: The blue signal is MOSI, the yellow signal is MISO. MOSI looks like expected while MISO is bouncing around the high level (pull-ups in place). The signal is too weak to be processed by my µC. Is my sensor defect or do I have to send something via SPI upfront to make MISO work properly? Thanks a lot in advance for your help. Best regards, Martin

Hi Robin, you are right. Please excuse the confusion and thanks a lot. With the code you provided I should be able to make it work. Best regards, Martin

Hello Robin, thanks a lot for your fast response. The example helps a bit. I can see that there are still a lot of Coines references. That is exactly the part I'm struggling with. Since I'm not using the evaluation board from Bosch I think the Coines environment is useless for me, right? Is there any other resources on how to make the BMI323 communicate with other platforms by using the API? Thanks a lot and best regards, Martin

Hello community, I'm trying to integrate the BMI323 into my Code Composer Studio project for TI microcontroller. In the provided API (which is not available at the Bosch GIT any longer for whatever reason) there are lots of bmi3-function calls that are not defined in any of the files. I honestly don't know where to start. Am I missing a layer on top of that API or am I expected to code these functions by myself? How can I make this sensor run within my TI project? Please excuse if these are stupid questions. I'm pretty new to this. Any help is much appreciated. Thanks a lot and best regards, Martin
