Well, step 1: read the datasheet: http://www.ti.com/lit/ug/slau601a/slau601a.pdf <quote> 2.1.5 SPI Configuration By default the BOOSTXL-K350QVG-S1 comes configured as a "4-wire" 8-bit SPI. This is the standard SPI on most MCUs with a hardware SPI peripheral. The user can reconfigure R2/R3 and R8/R9 to instead use "3-wire" 9-bit SPI. In this configuration, each SPI write is 9 bits instead of 8, allowing one fewer GPIO pin to be used. </quote> Regards, -- Robert Nelson https://rcn-ee.com/ -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
