IWR1642BOOST: can spi write config as non blocking call ?

terry fang

Part Number: IWR1642BOOST

Hi,

In mmwave_automotive_toolbox_2_6_0/labs/lab0001-driver-vital-signs example .it is using uart write function to send data to host. I am trying to replace uart write with spi write. however spi write seems a blocking call. and if host does not read fast enough it blocks there and a deadline missing assertion is hit. i am wondering can i config spi write to be non-blocking call ?

Thanks

Terry,

Please refer to the "SPI.h" file that is included in the SDK. The comments in the header file provide specifics with regard to implementation.

In the latest SDK, this file can be found here: C:\ti\mmwave_sdk_03_03_00_03\packages\ti\drivers\spi

Regards,
Kyle

Terry,

Please keep in mind that only blocking mode is supported in the SPI transfer call. You can try to modify the "transferTimout" parameter and see if that works.
