Hi,
Please try attached script. You need to go to Register Load , and open the file from there.
After that, the script will be selectable in "Script Select".
The L9961 board needs to be power by 12V DC at B+ / B- .
In the manual, the STM32 nucleo board can be powered by VREG of L9961 board or by the USB ( ST-LINK ) connected to PC.
If powering the STM32 nucleo board by USB, you need to set the J2 jumper ( VIO ) to 1-2 , to use VDD .
You can use multimeter to check VIO , it needs to be 3.3V for the I2C communication between L9961 and STM32 to work. ( otherwise, you can get communication error ).
Best Regards
KC
