Not exacly. Only odd color values affecting the strips, no meter i send to one or to five strips.

Ok, here is my actual testing code. No any other interrupts or so. Also when i do video streaming, there is no any interrupts too, everything working in the main loop. Sent you an email in PM.

We have 5 power supplies 350W each for all 40 strips, teensys powered by seperate adapter. So we can exclude power problem. Maked video stream test with sending only even numbers, and everything works great. So only problem in odd numbers.

Did another test - it seems that all even values of color works great, and all odd values having problem. Why that can be?

Im not sure about power, because first frame is always perfect, also no metter what color i setup. About 4 and 5 controller, its just me writing code from my memory. Edit: Just tested with external power supply for teensy. Same behavior. 100 to 254 values works good, 0 to 99 - first blink ok...

Played with r g b values and found that strips with code above working correct only with values from 100 to 254. With other values, colors are messed up on the second frame (when strip lights up in the second time). Can this be problem with byte to uint8_t cast?

Back to basic test program, blinking 5 strips in green color. Results (ignore 2 strips at the bottom, they are not connected): 1. http://cl.ly/image/460C1j1A3q25 First step - colors messed up and 6 leds missing at the end of the first strip. 2. http://cl.ly/image/3i3W1g3f1R1p Second step -...

Its first strip that i'm writing to. Will try to change order, as you suggest. Thanks.

Rewrote my code a little and get 2 teensys running with 5 strips on each. Also played with clock divider param - 16 working great for me. It seems that now i have no 7bits problem (didnt check with scope but data looks okey), maybe was some errors in example code or with timings, but now i have...

Thanks for your reply, now its clear for me. No, i'm not using hardware SPI. Just copied code from the example. Currently trying to run 5 ledcontrollers on each teensy. Using pins from 14 to 23. Will try to play with scope and timings today and will post at update what i got.

You are right, its 24 bits, not bytes. My bad. I've been able to run some tests and as you wrote, there is big problem with speed. I saw there is parameter in FastSPI_LED2 lib that changes SPI speed, but cant find anywhere what is max value for it. WS2801Controller<11, 13, 10, 3> LedController...

I cant figure out how to convert data from movie2serial to FastSPI_LED2 format. movie2serial already have 24 bits for each pixel, but fastspi needs data in this format - struct CRGB { byte r; byte g; byte b; }; - only 3 bytes long.

Hello! I have 40x WS2801 LED Strips and 8x Teensy 3.0 boards. Project is - 160x40 led display. Can someone point me where to start? Or even will this be possible with 8 teensy boards or i need something more powerful? Also, where i can read about DMA, because i cant find any documentation about...
