I need to raise the frequency of my two daisy chained TLC5940. I am using this library https://code.google.com/p/arduino-due-tlc5940/
and it works fine, but it outputs only about 513Hz. There are components in my circiut that will make noise (hdd voice coils for example), so a PWM frequency of about 20kHz would be great, but I don't know how to modify the library. I guess at 20kHz it will not be possible to drive the TLC5940 with 12bit, but 10 or 8 bit are also fine.
I know, the PWM on pins
3,4,5 and 6
6,7,8 and 9 can be modified with the pwm01 library (https://github.com/it-workshop/pwm01.h_by_randomvibe
), I just need the same thing on the TLC5940's.
Thanks in advance!
