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.

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

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

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.

[Pavel A.]

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

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

Hello @hemasree1 

Can you use CubeMX and where you can adjust the characteristics of the board you are looking for and then you can make a choice between them.

Best regards.

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

In the shed-load of RAM stakes we have the STM32U599 https://www.st.com/en/microcontrollers-microprocessors/stm32u599-5a9.html

With 512 Mbit (64MB) PSRAM  https://www.st.com/en/evaluation-tools/stm32u5a9j-dk.html
