Hello,
Thank you very much for your support. Please let me ask you another question about making patter sequence.
My firmware version is DLPR350PROM_v2.0.0，and I have to config DLPC350 only through I2C interface.
the pattern display data is streamed through the 24-bit RGB interface.
84Mhz clock, 1140 x 912, 70Hz,
1000000us / 70 / 3 = 4762 us (0x129A)
Three 7bit patterns, repeat.
According "DLPU010D-May 2013", “4.2 Trigger Mode 0 Example”, Setting as folling:
read : 0x20 -> 01 01 (i2c read Reg 0x20, get 01 )
read: 0x21 -> 01 01 (i2c read Reg 0x21, get 01 )
read: 0x22 -> 01 0e (i2c read Reg 0x22, get 0e )
1. E9 01 (i2c write Reg 0x69 = 01，enable pattern display mode)
2. EF 00 (I2C write Reg 0x6f = 00, pattern display data input source )
3. F5 02 01 02 00 (I2C write Reg 0x75 )
4. F0 00 (I2C write Reg 0x70 )
5. E6 00 00 11 A0 00 00 12 9A (I2C write Reg 0x66, exposure time = 0x11a0, frame time = 0x129a ) （Is the byte order correct?）
6.
(i) F7 02 (I2C write Reg 0x77, open mailbox)
(ii) F6 00 (I2C write Reg 0x76, mailbox offset )
(iii) ( I2C write Reg 0x78, pattern display lut data )
F8 01 77 06 (external positive trigger, pattern number 0; white, 7bit; buffer swap, insert black-fill)
F8 07 77 02 (no input trigger, pattern number 1; white, 7bit; no buffer swap, insert black-fill)
F8 0B 77 02 (no inpt trigger, pattern number 2; white, 7bit; no buffer swap, insert black-fill)
(iv) F7 00 (I2C write Reg 0x77, close mailbox )
7. FD 00 (I2C write Reg 0x7d, a dummy write)
read: 0x7D -> 01 08 ( innormal )
8.
read : 0x20 -> 01 41 （sequencer abort）
read: 0x21 -> 01 01
read: 0x22 -> 01 08
9. E5 02 (i2c write reg 0x65 : 02，start the sequence)
note：a. RGB24 stream signal （P1_VSYNC, P1_HSYNC, P1_DATEN, P1A_CLK）is always exiting.
b. The interval between every two I2C reading or writing operation is enough long.
I cannot get a normal Reg-0x7d-data, AND the hardware status is also wrong.
What's the error in my configurations?
I update firmware vertion to V3.0.0, and try again :
read : 0x20 -> 01 01 (i2c read Reg 0x20, get 01 )
read: 0x21 -> 01 01 (i2c read Reg 0x21, get 01 )
read: 0x22 -> 01 0e (i2c read Reg 0x22, get 0e )
1. E9 01 (i2c write Reg 0x69 = 01，enable pattern display mode)
2. EF 00 (I2C write Reg 0x6f = 00, pattern display data input source )
3. F5 02 01 02 00 (I2C write Reg 0x75 )
4. F0 00 (I2C write Reg 0x70 )
5. E6 A0 11 00 00 9A 12 00 00 (I2C write Reg 0x66, exposure time = 0x11a0, frame time = 0x129a ) （LSB to MSB order）
6.
(i) F7 02 (I2C write Reg 0x77, open mailbox)
(ii) F6 00 (I2C write Reg 0x76, mailbox offset )
(iii) ( I2C write Reg 0x78, pattern display lut data )
F8 01 77 06 (external positive trigger, pattern number 0; white, 7bit; buffer swap, insert black-fill)
F8 07 77 02 (no input trigger, pattern number 1; white, 7bit; no buffer swap, insert black-fill)
F8 0B 77 02 (no inpt trigger, pattern number 2; white, 7bit; no buffer swap, insert black-fill)
(iv) F7 00 (I2C write Reg 0x77, close mailbox )
7. FD 00 (I2C write Reg 0x7d, a dummy write)
read: 0x7D -> 01 00 ( seems normal)
8.
read : 0x20 -> 01 41 （sequencer abort）
read: 0x21 -> 01 01
read: 0x22 -> 01 0C
9. E5 02 (i2c write reg 0x65 : 02，start the sequence)
E5 02 ( first 0x65 writing command has no effect, the second 0x65 writing command light up the projector, and project out an innormal image )
The projection image is innormal, but two signal: trig_out_1 and trig_out_2 seems well:
I have read some TI's e2e post about I2C pattern configuration, I become confused,
Can pattern configuration be done merely through I2C interface ? my device has no USB interface.
Does anybody know?
