Migrating from esp32 to stm32

[ilcnet]

Hello dear BSTRobin
I have a project Bme688 + lora that works correctly with esp32 wroom microcontroller and my compiler is arduino, for a lot of reasons i want to change microcontroller to stm32, so my questions are:

1- what is minimum part number of stm32 products that necessary for Bme688 processing.

2- have we Bme688 libraries for stm32 in ardunio.

3- without a few base commands between esp32 and stm32, can i use my esp32 codes c++ for stm32 or i need another ide and library for Bme688 with stm32.

Thanks

Hi ilcnet,

1. For example, in latest BSEC package, libalgobsec.lib.Size.log mentioned the requirement of MCU Flash and RAM memmory size for "BSEC2.4.0.0_Generic_Release_23012023\algo\normal_version\bin\armcc\Cortex_M4F\libalgobsec.lib".
text data bss dec hex filename
24950 0 3720 28670 6ffe (TOTALS)

BSEC library support host architecture of Cortex_M0, Cortex_M0+, Cortex_M3, Cortex_M4, Cortex_M4F, Cortex_M7.

2.Latest BSEC-2.4.0.0 had supported Arduino C++ project and C project, see example under folder "C:\work\Solution\BSEC\BSEC2.4.0.0_Generic_Release_23012023\examples\BSEC_Integration_Examples\examples\bsec_iot_example". If you use STM32 under Arduino environment, you should migrate BSEC package to your platform; If you use STM32 under C programming environment, you could refer example code bsec_iot_example.c.

Dear BSTRobin thank you for your fast response, i don't understand if i want to use my own code c++ in arduino with esp32 for stm32 with arduino i need to change anything or not.
Best Regards

Hi ilcnet,

The interface associated with the hardware is bus_write(), bus_read(), and you need to see if your platform supports the code implementation within the function.
