Programming Notes and Examples
Issue Date: 02/03/21
Initialization functions are normally the first functions in the HAL library that an appli-
cation calls. These routine allow the application to learn a little about the controller and to
prepare the HAL library for use.
This function registers the S1D13506 device parameters with the HAL library. The device
parameters include such item as address range, register values, desired frame rate, and
more which are stored in the HAL_STRUCT structure pointed to by lpHalInfo. Addition-
ally this routine allocates system memory as address space for accessing registers and the
display buffer.
