The DLPC230-Q1 continuously commands the TPS99000-Q1 to capture specific ADC measurements throughout each video frame. These measurements are aligned to events in the DMD sequence, such as illumination enables or dark time. DLPC230-Q1 hardware stores the ADC measurements in buffered memory. The memory buffer is swapped each video frame so that DLPC230-Q1 software is continuously reading the previous frame's ADC measurement data.
The order in which each ADC measurement is captured is dependent on the order of events in a given sequence. Figure 5-28 demonstrates two example sequences with sequence-aligned ADC measurements to capture various illumination voltage levels. The same measurements are captured during each sequence and the results are placed in the same DLPC230-Q1 memory indexes, but the order in which the measurements are retrieved by the DLPC230-Q1 varies to accomodate the sequence timing.
The command parameters for the ADC Measurements command specify the desired measurement index range in DLPC230-Q1 memory from 0 to 63.
The flash header file defines the DLPC230-Q1 indexes and their associated TPS99000-Q1 ADC channels for a specific flash build.
