Dear Expert
Regarding the new firmware V9.0.1 provided by TI, the debugging verification results have the following issues:
The new firmware does not support the old control method: Write Pattern Order Table Entry (98h) (i.e. reconfiguring a pattern through IIC - a set of several patterns, each with several images, the color and exposure time of each pattern light);
Phenomenon: The configuration parameters for (98h) in the new and old software are different (see Figure 1). Through log iic analysis, the (98h) instruction sent by the new software is different from the original "dlpu075a. pdf" (see Figure 2 and Figure 3), with an additional byte.
Our configuration operation here is as follows: (It conforms to the 98h description in "dlpu075a. pdf" (see Figure 3)
IIC: 98 01 00 07 04 00 00 00 00 00 00 00 00 00 00 00 00 08 07 00 F4 01 00 00 C8 00 00 00 (24byte)
IIC: 98 00 01 01 01 00 00 00 00 00 00 00 00 00 00 08 07 00 F4 01 00 00 C8 00 00 00
IIC: 98 00 02 01 02 00 00 00 00 00 00 00 00 00 00 00 08 07 00 F4 01 00 00 C8 00 00 00
IIC: 98 00 03 01 04 00 00 00 00 00 00 00 00 00 00 00 00 08 07 00 F4 01 00 00 C8 00 00 00
Has the instruction configuration for this 98h been changed? And based on the new software approach, I have also configured the 25th byte of the 98h instruction as a Pattern Set Entry Index (see the attachment "Only configuring the 98h instruction like the ti software to see the trig is consistent, but the actual selected pattern does not meet expectations - do other configurations also need to be modified. kvdat"). The result is also a configuration failure, or does it mean that the overall configuration of the DLP system also needs to be modified? (Our previous configuration can be found in the attachment "DLP Control Process. docx")
Question: ① Is there an update to 'dlpu075a. pdf'? (Configure and control DLP system through iic)
② Have there been any corresponding changes to the initialization configuration of the DLP system? (If possible, could you provide a corresponding change point that matches our original configuration?)
