CC3235SF: CC3235SF + FATFS

Part Number: CC3235SF

Hello.

I'm developing an application using CC3235SF with FATFS over SPI with SD beakout to store data acquired from a sensor. I'm using TI driver include in simplelink_cc32xx_sdk_5_20_00_06.

At moment, bit rate is 2.5 MHz.

How can i set bit rate used with the SD?

Thanks.

Tom

    Hi Tom,

    The bit rate is hard-coded in the SD SPI driver, but essentially the bit rate is controlled by configuring the SPI instance CONFIG_SPI_0. The easiest way to change this may be to add source/ti/drivers/sd/SDSPI.c directly to your project and change the bit rate set during initialization.

    Best regards,

    Sarah
