I have a problem with the size of the compiled code for teensy 2.0.
This size is 106% of the available space.

I have 2 general questions for the experienced forum members:
1. Is it relational to reduce the code size below 100%?
2. How would you proceed in principle?

I can't post the code, but there are a few points:
- wire lib included
- SPI lib included
- Hardware serial used
- Flexitimer 2
- OLED SSD13xx lib included
- OneButton included

Using the aforementioned libraries, some functions are defined as well as setup () and loop ().

My coding level and kowlege of GCC is limited.
Can someone give me a direction on how to proceed here?
