Controlling MOSFETS through TLC5940 with Artnet

Hi people, I’m currently trying to construct a system that would generate 12 channels of PWM for controlling some high current LEDs via art net. So far, it seems that the TLC is the best option for doing this as others (such as SOFTPWM) look somewhat sketchy from what other users have said.

Long story shot, can anyone give me some guidance on how to make this art net sketch ( control the TLC?

Cheers in advance!
