Connect eval-l9963e-mcu to Arduino UNO

[alfonso_mauro]

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

[Andrew Neil]

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:

• talk directly to the L9963E battery management chip ?
• talk to the Onboard SPC574S64E3 microcontroller ?
• something else ?

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
