S32K388EVB-Q289_EVB FS5600 I2C example code

seanwu — Tue, 02 Dec 2025 12:04:04 GMT

Dear sir,

On the S32K388EVB-Q289 board, is there any sample code available for controlling the FS5600 via LPI2C1?
I noticed that the NTB0102GT is not suitable for use with I²C. Since this part is used on the EVB, does the functionality still work properly?
Or what should I do if I want to use LPI2C1 to control the FS5600?

Thanks.

BR,

Sean Wu

Hello @seanwu ,

You are correct that NTB0102GT is not suitable for I²C communication. The correct part for I²C level shifting should be NTS0102. NTB0102 and NTS0102 share the same footprint, so replacing NTB0102 with NTS0102 is straightforward

On the S32K388EVB-Q289, NTB0102GT is currently populated, which means that using LPI2C1 through this translator may lead to unreliable communication.

NXP provides a FS56 Generic Software Driver with Examples, available on the FS5600 product page:
