Use a cheap wifi router usb port and open dmx usb FTDI chip like artnet interface

[pablo trujillo]

Hi Simon

My name is Pablo I want to do a project and I would like to know if you could you help me.
The project involves using a wifi router tp link tl-wr703n and open dmx usb (ftdi chip).
I know, wifi router is easy to hack.
I read about your project artnet node, and saw the codes on your libartnet program.
My question is if I can do the same, but use any Mac or windows software to controller dmx, as also android app or ipad app.
It would be like making an open source controller artnet interface that anyone can use to be cheap.
I don't know if I can use the codes of libartnet to do this or should I use other codes.
Moreover I have to do a firmware with the codes and record them in the wifi router.
I read in openwrt, you can overwrite the firmware of this router.
Make this project is possible, or you think it's a crazy idea.

from already thank you very much

Pablo Trujillo

If I compile into the router libartnet I can use any dmx software to connect with my light or need be OLA

Hippy's link above is dead

Did you get OLA to work with FTDI on openwrt?

I can install libftdi with opkg but OLA has no FTDI plugin once installed

You can use a 8$ Orange Pi Zero. Connect the Ethernet from the OPi Zero to the WiFi router.

A full Art-Net 4 open source, cross platform, can be found here -> https://github.com/vanvught/rpidmx512/tree/master/lib-artnet

And ... maybe there is already firmware you can use out-of-the-box -> https://github.com/vanvught/h3dmx512-zip

OLA installs on a Raspberry Pi with FTDI support too. I thought this thread was about getting FTDI support on OpenWrt - which I would still very much like to see.

Using an Orange Pi Zero is much cheaper than using an FTDI solution. Moreover, when using the OPi Zero, then there is precise DMX timing and there is also RDM support.

Robb, for what it's worth, I have been using Arjans gear for the better part of a year now, maybe longer.  It works VERY well and is extremely inexpensive.

Hi Robb,

Can you share your config.log please and which version of OLA you're compiling? At the end of configure it should also list the plugins it's going to compile.

If I was to guess, it's probably just not finding libftdi, so not building support for it.

The OpenWRT package for ola includes libftdi1, so it should all just work:

Yes, however, the title of the post is " Use a cheap wifi router usb port and open dmx usb FTDI chip like artnet interface" & it doesn't get much cheaper than a $2 RS-485 to FTDI adapter since most people already have a wifi router.

Not to knock OPi, it looks like a cool board/project :)

[Marshall McHenry]

I think your challenge with the $2 RS485 adapters is that you're relying on the host for proper DMX timing.  I've tried that route more times than I care to admit, and I always got weird flickering or other abnormalities in the lighting.  With a micro-controller based adapter, you will never have those issues.

I just installed ola after installing libftdi

hmm, i'll try again

Thank you

There is also an open-hardware 2x DMX board for the Orange Pi Zero -> https://github.com/victor-lallemand/OPI-zero-2-out-dmx

For just a few $'s more you have a safe opto-isolated solution.

Hi Arjan, that is very interesting.  Do you have any pictures of a PCB based on that design?

Seems as though opkg is installing ola-.0.10.6 & libftdi1 is in ola-.0.10.7

I think I need to upgrade openwrt 19.07 to get the newer version ola-0.10.7 with ftdi support

Agreed, although KeeperOfTheKeys has managed RDM via an FTDI, which has some stricter host timing requirements:

Does libftdi/libftdi0 work with OLA 0.10.6 otherwise?
