4 Example Configuration for Pin Constrained Applications

This section provides the HIC configuration that uses the least number of I/O pins connected to C2000 EMIF controller. A Host side and Device side example for this configuration is provided in the C2000ware Package. The Host memory controller used in this example is the F2838x EMIF connected to a F28002x HIC device.

The example projects can be accessed here:

  • Host side:<C2000Ware InstallDir>\driverlib\f2838x\examples\c28x\emif\CCS\emif_ex8_8bit_asram_hic_adc
  • Device side: <C2000Ware Install Dir>\driverlib\f28002x\examples\hic\CCS\hic_ex2_config_8bit_adc
