VM_DCL_HANDLE spi_handle; vm_dcl_spi_mode_t spi_data; spi_handle = vm_dcl_open(VM_DCL_SPI_PORT1,0); if(VM_DCL_HANDLE_INVALID==spi_handle) return; spi_data.mode = SPI_MODE_DEASSERT; spi_data.is_enable = KAL_TRUE; vm_dcl_control(spi_handle,VM_DCL_SPI_CONTROL_SET_MODE,(void *)&spi_data); //To do something.
