Hi, I asked this question on the Teensy project guidance forums but I was told that it would be best to ask someone at PixelMatix, so I am posting my (revised) question here now. Hopefully someone can help/guide me.
I want to create a 32x32 RGB LED matrix wall,
connected to the internet (Ethernet or Wifi)
to contact a webservice for new content to display.
I was thinking about using these components:
- Teensy 3.1
- SmartMatrix SD shield
- 32x32 RGB LED matrix
Now, I would also like to know whether it would be possible to play raw audio files
using the Audio library together with this configuration.
I am not sure how I should connect a speaker to the Teensy,
or would I have to use the Audio Adaptor?
If so, can both the SmartMatrix SD shield and the Audio Adapter be connected?
Paul Stoffregen already answered at the forums that I could use the DAC pin for 12 bit mono output
if that was enough and for this project it is enough. The DAC pin is still accessible with this shield attached?
Apart from that. The ethernet (or wifi) connection.
Do I need another shield or adaptor for that? Any idea what I could do?
Is it possible?
And lastly, would I need two power cables to power both the matrix panel and the teensy+shield?
Thanks for the help.
