Other Parts Discussed in Thread: TFP401
Hi team,
I have been trying to use DLPDLCR2000EVM in two ways, both failed to work:
1) by a Raspberry Pi 4b+ as described here: frederickvandenbosch.be/
also here: e2e.ti.com/.../dlpdlcr2000evm-connection-to-raspberry-pi-4-model-b
On the raspberry, after wiring and editing /boot/config.txt as described in the first link, I get the following
$ sudo i2cdetect -l
i2c-1 i2c bcm2835 I2C adapter I2C adapter
i2c-7 i2c ffffffff00000002.i2c I2C adapter
$ sudo i2cdetect -y 7
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- 1b -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- 57 -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --
Then running
sudo i2cset -y 7 0x1b 0x0c 0x00 0x00 0x00 0x13 i
sudo i2cset -y 7 0x1b 0x0b 0x00 0x00 0x00 0x00 i
however the flash screen still is playing the splash screen
2) I used adafruit hdmi/dvi decoder TFP401 with a NHD-TFT40 new heaven board wired to EVM, where parallel RGB888 vid data pins were connected to the NHD-TFT40 pins, along with the VSYNC, HSYNC, DATAEN and CLCK pins. Then, through a Raspberry Pi, I sent the I2C commands above to the board.
In both methods, only the spalsh screen keeps playing. Could you please help me how to get some picture out of the DLP.
thank you.
Best regards,
William
