Hi all,
I am attempting to make a wearable 32 x 32 pixel display using 4 16x16 flexible ws2811 ws2812b pixel panels.
For this I have purchased the following hardware :
1 x teensy 3.1
1 X octows2811 adapter
1 x audio adapter
1 x nrf8001 BLE 4.0 bluetooth breakout
4 16x16 flexible ws2811 ws2812b pixel panels
My goal is to connect the 4 16x16 panels using the octows2811 library and to
read video data from the SD card on the audio adapter (and later to also use the audio features of the card).
The panels appear to be the same as a 256 ws2812b led strip shaped into a solid 16x16 square in a zigzag arrangement.
I want to have the 4 panels arranged into a 32x32 grid like so
[a]
[c][d]
and use 4 channels of the 8 available on the teensy one for each panel.
When looking at configuring the octows2811 library the LED_WIDTH setting
seems to assume that a single strip covers at least one row so I can't see a way to configure it for tiled matrix displays similar to the Adafruit_NeoMatrix library
Can anyone suggest a way to configure it for this arrangement, or an easy way to modify the library to achieve the mapping I need ?
Can the teensy 3.1, the audio adapter, and the octows2811 adapter all be stacked on top of each other with headers ?
Do any pins need to be removed or jumpered to do this ( i read something about removing pin 4 for sd card access on the sd card adapter when using the ws2811 adapter )
Will all these cards work together or will some features be disabled or fail with this combination of hardware i.e. are there any conflicting pins on these cards ?
Thanks for any advise, I'm fairly new to all this stuff, so if these questions seem silly they probably are
regards
Lynton
