I have only one cc2640r2

A am trying to spi master example on cc2640r2

i want to check clk on cro

my on board connection is below

cs= DIO 11

CLK = DIO 10

MOSI = DIO 09

MISO = DIO 08

I checking as below step

CRO GND to CC2640R2 GND pin

One probe connected to DIO 10

trigger set 3.5 v

time = 500 us

can you suggest me how to check clock signal

Hi Akshay,

The SPI master can generate a SPI CLK output signal simply by calling the SPI_transfer function, even if there is not a slave device connected. I recommend that you review the SPI TI Driver Runtime APIs for code examples alongside evaluating the spimaster project. The probe trigger needs to be below 3.3V as this is the operating voltage of the LAUNCHXL-CC2640R2 hardware.

Regards,
Ryan

i am new user for ccs and 2640r2

i am trying a spi communication

the available example include 2 cc2640r2 board

i have one board

so i want to spi communicate to other sensor

so can you explain simple master example for send or read data from slave

or spi communication /spi communication steps

You would reference the resources already provided in accordance with the specifications provided in the sensor datasheet. You can also search the E2E forum for similar requests.
