DLP2000 evaluation board
in Propeller 2
Just happened to see the DLP2000 evaluation board on Digikey: 296-47119-ND
It's a $102 tiny projector. I think this has been around for a while.
But, would be fun to connect up to a P2 chip.
It can accept 24-bit parallel interface, just like a TFT LCD module (after some I2C setup.)
This one is fairly low resolution at 640x360.
But, this is actually good for P2 as can easily do a palleted 8bpp image without external ram.

Sounds really amazing !!
Just also see it.
That is very nifty - I find some comments suggesting Max resolution: 854 x 480 ?
What is interesting is that it looks like you can take the frame rate almost down to zero...
Might be able to use that exact board actually with a 60-position ffc cable to some new board that mates to this thing...
It may not need 24b ? I found a link setting this up on a Rasp-Pi, using 18b video
There is a Pi bridge PCB out there, that should work on my P2D2Pi PCB layout ?
"The following block needs to be appended to /boot/config.txt. This can be done straight from the Raspberry Pi, or while the SD card is mounted on the PC."

Not sure what dpi_output_format=458773 does, or maybe the dtoverlay=dpi18 is enough to use 18bpp ?I think this is the default setting for the device.
Apparently, you can connect to a PC and use like a monitor.
But, you have to download special timing info...
So, that's the challenge there, finding out what timing you need to make it work.
Fortunately, I think the P2 HDMI interface will let us use whatever timing we want...
