10.2 Sample code without using the S1D13705 HAL API

This second sample demonstrates exactly the same sequence as the first however the HAL is not used, all manipulation is done by directly accessing the registers.

**===========================================================================

**SAMPLE2.C - Sample code demonstrating a direct access of the S1D13705.

**

**The sample code using direct S1D13705 access

**will configure for the following:

**

**320x240 Single Color 4-bit STN

**8 bpp color depth - 70 Hz Frame Rate (6 MHz CLKi)

**Notes:

**1) This code is written to be compiled for use under 32-bit

**Windows. In order to function the vxd file S1D13X0X.VXD must

**be in the \WINDOWS\SYSTEM directory.

**2) Register setup is done with discreet writes rather than being table

**driven. This allows for clear commenting. It is more efficient to

**loop through the array writing each element to a control register.

**3) The array of register values as produced by 13705CFG.EXE is included

**here. I write the registers directly rather than refer to the register

**array in the sample code.
