Spi communication with arduino

[Texe07]

• FRDM33772BSPIEVB
• Evaluation Board for MC33772 with SPI Communication.
• This board need to communicated with arduino uno with spi how to do it any references for it.
• also checked the document but no register related information found.. Any supportive document for this??
• Thanx : )

Hi @Texe07,

You can check the user guide in order to see some specification of how to use the FRDM33772BSPIEVB with Arduino UNO.

The first thing would be the connections, since the SPI modules in both boards need to be connected correctly.
See Table 12. Jumper Setting to Work with Arduino R3 of the user guide.

Once the connections are correct you can check the information about the SPI interface in the user guide.
See section 4.13 SPI communication interface of the user guide.

Since Arduino UNO is not a NXP product we don't have any specific documentation regarding the implementation of the FRDM33772BSPIEVB with Arduino UNO, but you can take a look to the following post where it explains the SPI communication setup between S32K1xx boards and MC3377xBSPI Battery Cell Controllers.

Also, you can refer to the following GUI design based on KL25Z.

Hope it helps you!
