8.3.1.1 Independent Mode
Figure 8-1 shows an implementation of a 16 × 32 RGB LED matrix using two LP5890s in independent mode. Each device is responsible for its own 16 × 16 RGB LED matrix which means that all the data for section A is stored in Device1 and the data for section B is stored in Device2.
Figure 8-1 Two Devices in Independent ModeThe unused line must be assigned to the last several lines of the device. For example, if there are only 14 scanning lines, then the two unused lines should be assigned to 1_LS14 and 1_LS15.
