heatshrink Compression Library for Embedded Data
heatshrink: An Embedded Data Compression Library
‘When compiled for an Arduino microcontroller by avr-gcc, the decoder only needs about 1 KB of program ROM space. (I’m working on getting it smaller, and this will vary from platform to platform. On my project’s hardware platform, it’s under 800 bytes.)’
