3.4 Advanced System Setup

To describe the advanced system setup, an example is used that is depicted in Figure 3-2.

Advanced System Example With 2 Daisy Chains Figure 3-2 Advanced System Example With 2 Daisy Chains

The sample code supports up to two daisy chains. The number of actual used chains is defined by macro BUS_NUM in file system_info.h.

// Total buses supported
#define BUS_NUM           2

Each chain can have a different number of cascaded devices. Therefore, besides macro CASCADED_UNITS_BUS1 that was described in Section 3.3, there is also macro CASCADED_UNITS_BUS2 in file system_info.h. In the example, chain 1 has two cascaded devices and chain 2 has three cascaded devices.

#define CASCADED_UNITS_BUS1   2
#define CASCADED_UNITS_BUS2   3
