Hi,

   

 I use the spi interface of the fx3,the MOSI pin of the spi interface is low after the spi initializated.I have connected a Pull up resistor to this pin.How can i do to set this pin is high when the spi interface initialization?

Hi,

   

No external pull ups are required on the MOSI and MISO pins.Did you try with our example firmware and observe the same results?

yes,the results are same,the MOSI pin is low in the idle state.
