Features

Logic function calculation

The AOI module supports a configurable number of event outputs, where each event output represents a user-programmed combinational boolean function based on four event inputs. The key features of this module include: Four dedicated inputs for each event output. User-programmable combinational boolean function evaluation for each event output. Memory-mapped device connected to a slave peripheral (IPS) bus. Configurable number of event outputs.

how this driver is designed

This driver is designed around the basic configuration unit of AOI output which get input signal,

aoi input configurations is defined with enumeration name as aoi_input_config_t. This enumeration list all AOI input configurations with its meaning provided in enumerator.

This driver provide several function group to do with the Event operation .

• Initialization and Deinitialization groups
  • This group initialize / deinitialize the AOI module not relevant to specific output signal.
• Configuration group
  • This gorup a AOI output and input with all supported configuration.

How to use this driver

• Action needed outside driver
• Initialize AOI module calling AOI_Init(), Note that this only need be called once.
• Configure the selected AOI module event by calling AOI_SetEventLogicConfig.
• Get the AOI module event by calling AOI_GetEventLogicConfig.
