I use the CC26X2 platform, SDK Version is 5.20.00.52. in my BLE Application. I use the SPI driver to communicate with another IC.
this IC need pull high CS line within 10us when no data communicaion is needed, otherwise,some function couldn't work.
the code piece is below, it couldn't meet my requirement.
so, I use the "USING_DRIVERLIB" macro code. it seems to directly operate the lower registers. it could meet my requirement(wihin 10us after write SPI data and pull up CS port)
but, I occured a problem : when system enter standby lowe-power mode ,and then exit this mode to the normal mode, the SPI couldn't work, (the SPI clock dont work)
could you tell me the constraint of the driverlib function and the TI-RTOS drvier function?
could I use the driverlib funcition in the TI-RTOS project?
how can I reslove this problem of wakeup from standby mode. (I need the SPI work norml when exit the standby mode)
