Hi, i am an embedded electronic engineer and lately i have a project named 'plug meter' based on an STM32 MCU and the STPM01 AFE, but i couldn't establish the SPI communication between AFE and MCU because there are no libraries to read and write through SPI, please help me!

    No, in fact i am willing to design my own board, using a MCU from ST (STM32f030K6T) and an AFE module (STPM...).

    I imagined this design:

    There for, i need to establish the low level communication layer between MCU and AFE, but i couldn't find in your datasheet, some software libraries to facilitate the communication; (only hardware description of SPI :

    0690X0000060B1xQAE.png

    Am i forced to create my own Hardware Abstraction Layer (HAL) for the AFE ??

    There is other companies providing a regular SPI communication Interface (already compatible with any MCU).

    So my question is: 

    Is there any

     libraries to read and write through SPI ? if not how can i do it then (considering that i will but the STPM.. and MCU separably and design my board)?

    Thank you

    You design is something like this... ?

    I suggest to use STPM32/ STPM33 / STPM34

    Look for Evaluation Tool Software at

    For new designs STPM32/33/34 recommended
