Description

vm_dcl_spi_capability_t exposes SPI capabilities which can be queried. This structure is used as a parameter of VM_DCL_SPI_CONTROL_QUERY_CAPABILITY.

Example

 VM_DCL_HANDLE spi_handle;
 vm_dcl_spi_capability_t spi_data;
spi_handle = vm_dcl_open(VM_DCL_SPI_PORT1,0);
if(VM_DCL_HANDLE_INVALID==spi_handle) return;
 vm_dcl_control(spi_handle,VM_DCL_SPI_CONTROL_QUERY_CAPABILITY,(void *)&spi_data);
//To do something.
