BeagleBone Black working by SPI with TLC5927

Hello,

I'm having some problems to enter in the Special Mode of TLC5927.


Now i'm using SPI communication to send data, which works correct, but I can't enter in Special mode, because i can't synchronize the clock with my OE and LE.

I already tried to get the CLK signal with other GPIO and generate a interrupt on my program to finally toogle OE and LE, but it's looks like the GPIOs are too slow.


Do you can help me with this problem? I'm using C++
