Demo Program
The Z86229/230 Demo Program supports the eZSelect data decoder ref-
erence design. Because the eZSelect VBI decoders are application-spe-
cific devices and not like microcontrollers, there are only two ways to
communicate with them: the I²C and SPI buses. The Demo Program acts
as the controlling firmware and uses a PC as the main host controller to
send commands to the Z86229/Z86230 devices. The Demo Program also
conveys data from the reference design to the PC monitor. The following
procedure describes how to install and use the Demo Program.
Software Installation
The Z86229/Z86230 Demo Program is contained on the demo software
CD. Follow the instructions on the screen to finish the installation.
