Hello I have been working with the dlp2000 evm using a raspberry pi zero and have been having some trouble. I can ssh into it and have set up the boot files like described in https://www.mickmake.com/post/build-a-pi-zero-w-pocket-projector-project/ . However, I still can’t get the parallel interface to work. I can switch between test images and have even played around with the input resolution and pixel resolution so that it matched the parallel input specifications according to the programming guide ( https://www.ti.com/lit/ug/dlpu013a/dlpu013a.pdf?ts=1699917338782 ) . But still when I run (sudo i2cset -y 2 0x1b 0x0b 0x00 0x00 0x00 0x00 i) nothing happens. I was wondering if I could have some help troubleshooting this issue.
Thanks,
Abby
Hello Abby,
Welcome to the E2E forum. Thank you for your business!
In the tutorial you linked, they set the resolution to 19 – WVGA-854 landscape (command 0x0c, data 0x13). Is this the resolution you are trying to set?
Are you able to set the source (command 0x0b) to any other value other than 0x0? The parallel interface supports both RGB and YCrCb data formats. Frames are assumed to be periodic in nature.
Best,
Maxine
