The code consumes a significant amount of Stack and Heap memory! #40
Description
I'm using this library on STM32 and Keil. I encountered an issue when trying to generate QR codes above version 8. After some experimentation, I discovered that it requires additional Heap and Stack memory.
Currently, with 12KB of Stack and 4KB of Heap memory allocated, I am able to generate QR codes up to version 13. However, for higher versions, more memory is needed, which I currently lack. I attempted to set LOCK_VERSION to 14, but it did not resolve the issue.
Is there a way to optimize memory usage and reduce consumption?
