So what debugging have you done so far, and what have you learned from that?

Are you sure that the LEDs are mounted the correct way around?

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

    Are you using an internal oscillator for the MCU? According to the schematic, you only have a low speed oscillator crystal connected. Share your code and clock and IO settings.
