The SPI driver validation settings are defined in the DV_SPI_Config.h configuration file.

DV_SPI_Config.h configuration file in Configuration Wizard view mode

Some settings depend on the test environment and may require adjustment to ensure proper operation of the SPI Driver Validation suite.

Configuration settings

Driver_SPI#** selects the driver instance to be tested.
Example: to test Driver_SPI2, set this value to 2.

Configuration** contains settings for Test Mode, SPI Server, and Tests:

Test Mode: Loopback or SPI Server.
- Loopback is recommended for initial validation of Master functionality. It requires MOSI and MISO to be connected together to verify basic operation.
- For full CMSIS-Driver SPI compliance, use SPI Server mode.
SPI Server (applies only when Test Mode: SPI Server is selected):
Defines communication settings between Driver Validation and the SPI Server and must match the Server.
- Fixed parameters:
  - Clock/Frame: CPOL=0, CPHA=0
  - Data Bits: 8
  - Bit Order: MSB to LSB
- Configurable parameters:
  - Slave Select - Software Controlled (driver toggles SS using ARM_SPI_CONTROL_SS) or Hardware Controlled.
  - Bus Speed - nominal bus speed for reliable command exchange with the Server.
Tests: configuration for test execution.
- Default settings - defaults for data exchange tests (see Data Exchange).
- Bus Speed - minimum/maximum speeds used by SPI_Bus_Speed_Min and SPI_Bus_Speed_Max.
- Number of Items - item counts (including odd/unusual) used by SPI_Number_Of_Items to verify conformance.
Tests** section - enable/disable test groups (and individual tests):
Driver Management - see Driver Management.
Data Exchange - see Data Exchange.
Event - see Event.
