Yes, I have code that works in both decoding the DMX stream as well as dimming. I am still working on the dimmer part, since it does not perform as well as I would like. Specifically, at low values the lights do not turn on until up around a dimming value of 50. I believe this is due to the the physics of the lamps, since many commercial dimmers provide a "standby" voltage to keep incandescent filaments warm. Also, turning on triacs using the delay algorithm is not very linear, so there is not a lot of energy available at low dimming values; again commercial dimmers try to compensate for this with different dimming profiles. I have the attached the code, as you can see it is set up for 6 channels but can be easily extended to 8. I have not tested at 8 so I cannot swear there is enough bandwidth to successfully operate.
