Hi,

I'm trying to use a TLC59116IPWR that I made a pcb with but nothing happens. Here is the schematics:

First, I noticed I might need to actually wire RESET and REXT, but I tried to do so by touching resistors to the pins and couldn't make it work anyway, might not be the best way to test though...

But is there any other issues you could see in my schematics?

SCL0 and SDA0 are connected to pins 19 and 18 of Teensy 4.0.

And regarding code I'm testing with this library, and its Sinewave example:

Thanks
