no success... I've tried a lot but never got it to work...

unfortunately not...

I don't have the expertise to design the required 3 different types of power supply. The connector also was a problem considering it has 80 pins, it would require a bunch of layers to design the pcb.

have you managed to do that??

Looks like you need to update your local version of available packages, I just checked the repository and, for example. the current version of xproto is xproto-7.0.27-1-any.pkg.tar.xz If you want to be stuck at the same package build date as the packages you listed, you will need to use the arch li...

Hi there... I'm trying to build xserver the same way you did, but I keep getting a message about some packages being a lower version than required. Requested 'xtrans >= 1.3.5' but version of XTrans is 1.2.7 Requested 'xproto >= 7.0.26' but version of Xproto is 7.0.23 Requested 'randrproto >= 1.4.0' ...

Look at page 19 of the TI datasheet, the fact that timings are in nano-seconds should warn you that you don't have a hope in hell of generating the timing from a raspberry pi. A very fast FPGA maybe, if you're very good with Verilog. In page 19, they specify the max DCLCK cycle as 12.5ns, which ref...

Hi there!! 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...

Brilliant matte!!!! Congratulations!!! I was wondering if this DMA approach allows a "maximum" number of pulses, so the pulses would stop after it's reached? If so, this method could also be used to reliably control stepper drivers, like pololu 4988 ones. anyhow... just brilliant!!! cheers matte... -H
