Hi; i was trying to connect my eval-l9963e-mcu to an arduino uno, to comunicate by SPI. How can i do this?

As its name suggests, the EVAL-L9963E-MCU already has an on-board MCU - so what is the purpose of connecting to an Arduino?

Do you want the Arduino SPI to:

my final intention is to take the datas from the bms and comunicate in can bus. so i was thinking to comunicate with an arduino in SPI, and at the end communicate by can bus

and where are the MISO,MOSI,CS... on the boardScreenshot 2025-02-18 160245.png

As always, the schematics are on the 'CAD Resources' tab of the Product Page:

Also check-out the Documentation:

Hi everybody, I am working with the eval-l9963e-mcu. And my intent is to connect the evaluation board with an arduino uno to see the cell voltage in the serial monitor. I tried to connect the MISO,MOSI,CS, CLOCK, GND to the pin of arduino, but when i connect the cells nothing happens on the display.

thk you everybody for the attentions.
