Programming Notes and Examples
Issue Date: 01/02/23
Initialization functions are normally the first functions in the HAL library that an appli-
cation calls. These routines return information about the controller and prepare the HAL
library for use.
This function registers the S1D13706 device parameters with the HAL library. The device
parameters include such items as address range, register values, desired frame rate, etc.
These parameters are stored in the HAL_STRUCT structure pointed to by lpHalInfo.
Additionally this routine allocates system memory as address space for accessing registers
and the display buffer.
