* All device handlers are scheduled by adding them into
|
|
* Polling Sequence Tables (PST) to satisfy stricter timing requirements of
|
|
* device communication, a device handler has four different communication steps:
|
|
* 1. DeviceHandlerIF::SEND_WRITE -> Send write via interface
|
|
* 2. DeviceHandlerIF::GET_WRITE -> Get confirmation for write
|
|
* 3. DeviceHandlerIF::SEND_READ -> Send read request
|
|
* 4. DeviceHandlerIF::GET_READ -> Read from interface
|
|
* The PST specifies precisely when the respective ComIF functions are called
|
|
* during the communication cycle time.
|
|
* The task is created using the FixedTimeslotTaskIF,
|
|
* which utilises the underlying Operating System Abstraction Layer (OSAL)
|
