Regarding integration of STM32 series and BMI323

[hemasree1]

Hello everyone!

Please assist me as I need a BMI323 sensor integrated on any STM32 series on a single board where I will be performing Machine Learning. I'm hoping to hear from you shortly.

Hello @hemasree1 

I suggest you to create your own design with an the STM32 MCU that satisfy your needs ( pinout, conso, API,...). And add the BMI323 sensor to this design using SPI, I2C (or I3C for the STM32H5.)

If you want any assistance from community members and experts, make your questions more detailed (subject, board or MCU to use, API, SW, HW,...)

Best regards.

From the document, this device can connect over I2C, I3C and SPI. Only STM32H5 currently has I3C. Any other STM32 has both SPI and I2C. Which STM32 or board do you want to use? Do you know how to use one of these interfaces of STM32?

Expect you'll need to buy on a shuttle board and wire up to a NUCLEO or DISCO, perhaps via a Arduino prototype shield board?

Don't see anything off-the-shelf.

Okay, may I know which MCU suits more to integrate BMI323 on STM series?

[Tesla DeLorean]

They all look capable of interfacing, focus on your processing needs.

As said @Tesla DeLorean you can use all STM32 MCUs. I think you can use the STMH5 series wish support SPI,I2C and I3C and more other interfaces that may help you. You can find all information you needhere. Also you can use this firmware to program it.

Best regards.

So you even have not decided on the board or MCU.... Well then there are two routes: 1. Find a powerful STM32 for your "ML" processing. 2. Get a board/SBC/SOM familiar to you for the ML processing (may be running Linux and the software provided by Bosch for this sensor) and use a lower-end cheap STM32 for interfacing with the sensor and preprocessing

[hemasree1]

Can anyone help me with choosing a stm32 series which provides high RAM size? I need to perfrom Machine learning on it.

Again, are you looking for a bare STM32 or a board with external RAM and flash?
