Hello,
We encountered a problem when developing structured light product using DPLC3470 and DLP2010NIR with DLPC-API-1.10.We want to project multiple images, it is found that only the first image can be projected. DLPC34XX_SeadPatternOrderTableEntry (1,&entry)function returns a value of 0. The same code works normally on DPLC3478 and DLP3010LC platforms.
The firmware for DPLC3470 is FWSel_SLPC3470_DLPA2005_pm1_i2c0x36-v9p2p0-RED_LED-ONLY
Thank you,

Thank you for your reply.
EVMs are made by custom.
For example: we have 4 pattern set, the number of patterns in each set is 1, the pattern order table have 4 entries.
We found that only the first pattern set can be projected. TRIG_OUT_1 (Frame Trigger) and TRIG_OUT_2 (Pattern Trigger) are not correct, as shown below(run once).
The patterns data stored in flash as shown below.
The returns of API DLPC34XX_ReadPatternOrderTableEntry (0,&entry) are correct.
The returns of API DLPC34XX_ReadPatternOrderTableEntry (1,&entry) are 0s.
The same code for generating patterns data works normally on DPLC3478 and DLP3010LC platforms.
If we have 1 pattern set, the number of patterns in each set is 1,the pattern order table have 1 entry. the patterns can be projected correctly. TRIG_OUT_1 (Frame Trigger) and TRIG_OUT_2 (Pattern Trigger) are correct, as shown below(run 10 times).
Thank you, Aaron
The return of DLPC34XX_ReadInternalPatternStatus(&state) as shown below
The return of DLPC34XX_ReadPatternOrderTableEntry(0, &entry) as shown below
The return of DLPC34XX_ReadPatternOrderTableEntry(1, &entry) as shown below
The return of DLPC34XX_ReadPatternOrderTableEntry(2, &entry) as shown below
The return of DLPC34XX_ReadPatternOrderTableEntry(3, &entry) as shown below
Correct as follows
The return of DLPC34XX_ReadPatternOrderTableEntry(2, &entry) as shown below
The return of DLPC34XX_ReadPatternOrderTableEntry(3, &entry) as shown below
Thank you for your reply
The firmware version for DLP3478 platform can project multiple images is shown below
We also tested the firmware FWSel_DLPC3478_DLPA2005_pm1_i2c0x36_v9p2p0_RED_LED_ONLY on the DLPC3478 platform and found that it could not correctly project multiple images.
