SPI arduino uno / labview

[pdefesche]

Hi,

I’m experimenting with the Arduino Uno’s SPI using the labview arduino toolkit. Need to send registers to a device with a SCLK: 2Mhz and the timing between two registers needs to be 2tSCLK. How can I manage this 2tSCLK between the two registers?

2tSCLK = 1uS

In my VI I can successfully write the bytes with the array, but when I check the signal on the oscilloscope I notice between two registers the timing is 250uS and while loop: 500uS.

Hope someone can help me with this.

Oscilloscope:

byte 1: decimal value: 8
