TLC5958: How to light on the LED matrix buy using two TLC5958 LED driver ICs ?

Part Number: TLC5958
Other Parts Discussed in Thread: LP55281, LED171596A

Dear Sir,

I designed a 23*23 RGB LED matrix and used two TLC5958 LED dirve ICs for circuit design.

The following documents were referenced:
1. TLC5958 datasheet
2. tidr683.pdf-tidr688.pdf
3. slva645_5_.pdf

Circuit design drawings such as attachment files.

LED Board.pdf

My MCU is using Nordic nRF52832, but I have been unable to properly illuminate the LED.

I have rewritten it with reference to this article and still cannot be lit normally.

TLC5958: sample code

Have any partners can provide the code of the 64*64 RGB LED matrix that is lit in the file "slva645_5_.pdf" to me?
