Subject of the issue

Error When used on Raspberry Pico

Your Environment

Library Version: Latest Arduino IDE version: Any Host OS and Version: Win 11 CPU Hardware model/type: Matrix hardware model/type: [ ] Parola [ ] Generic [ ] ICStation [X ] FC-16 [ ] Custom (describe how wired)

Steps to Reproduce

Explain how to reproduce this issue. Please provide working code below to demonstrate the issue. Upload any code that works on Arduino uno/nano it will not work on Pico

Expected Behaviour

Explain what should happen. Load Example hello code, Hello should display

Actual Behaviour

Explain what happens instead. Provide log messages if relevant. Just get a few LED flickering very fast on top or bottom line in center

Code Demonstrating the Issue

Insert your compilable code here (no code snippets).
````// Program to demonstrate the MD_Parola library
