I'm trying to build an interface board to power up and control an TI DLP Lightengine directly from the Pi. Essentially, I want to control the DMD Micromirror array directly (the DLP DMD Chip - http://www.ti.com/lit/ds/symlink/dlp4500.pdf) to generate images, without using the control chip from TI (the DLPC6401 control chip - http://www.ti.com/lit/ds/symlink/dlpc6401.pdf), which seems to me a way more complicated chip to design a board to, waaaaaay above my level!!
Although the DLPC6401 controller chip has a nice i2c interface and all, I don't even known were to start to build a protoboard for it.
So, I'm choosing the path of using the rPI directly as the controller chip, which would also make the whole interface way cheaper.
As my electronic knowledge is essentially hobbyist, I'm having a bit of a hard time to get the barebones of a prototype PCB that would connect the DLP Lightengine connector (AXT580124 - http://www3.panasonic.biz/ac/e_download ... ng_f4s.pdf) to a couple of MCP23017 chips, so I can access all the 24 data ports, plus the other 8 control/reset ports to start "hacking/trial and error" learning on how to control the DMD chip device.
Apart from that, I also need to supply all the necessary voltages (VCC –0.5-4V, VREF –0.5-4V, VOFFSET –0.50-8.75V, VBIAS –0.5,17.0V, VRESET –11,0.5V) properly, and last, power up all the 3 RGB high power LEDs!
My initial challenge here has being to figure how to sold the AXT580124 connector to a protoboard of some sort, so I can start prototyping the connections to the MCP23017 chips and voltages.
Does anybody knowns if Is there any protoboard that would accomodate the AXT580124 80 pins connector (0.15mm terminals with 0.40mm of space in between)?
Or do I have to build one from scratch just for that connector?
PS: For the curious, the idea is, essentially, to turn the rPi into a smart DLP projector, to be used in 3d printers, scanners or anything else you think about it!!
