Last days, i got a custom motion sensor board based on STM32F401RE
Sorry, post without complete typed.
On my board,there are some motion sensors, like: HTS221 LP25HB LSM303AGR .
Then i found a similar project MKI109V2 and MKI109V3, i want to port my board with the software Unico .
Source code of the firmware for the STEVAL-MKI109V2 (eMotion) board is in STSW-MKI109W
but i cant find the firmware for STEVAL-MKI109V3, Is that a open source project, where can i download the soucecode.
Waiting for your kind reply. thanks.
The source code of the firmware for STEVAL-MKI109V3 is not open source so far, and is not available online.
I can recommend you to check X-CUBE-MEMS1 software package where you can find source code for NUCLEO-F401 and expansion board X-NUCLEO-IKS01A2 which contains LSM303AGR, HTS221, LPS22HB, ...
STSW-MKI109L or STSW-MKI109M or STSW-MKI109W
Either one of them contains eMotionV2_REL_5.0.0.zip , which would be the firmware source code for ST eMotion board.
Current release v5.0.0 supports all the sensors you listed.
Miroslav's suggestion is also a good start.
