Hi all, I am using STM32 F411 Discovery board and am facing an issue with compression, i tried different compression libraries (zlib, mzip etc) all are using File system, unfortunately the F411 Discovery does not supporting Local File system, my concern is i want to compress some sensor data of size of below 1KB to .zip format, because the client server only accept data in .zip format, so i am looking for buffer to buffer compression libraries if any available,

else please suggest any other way that available to solve my problem,

i am using STM32 Cube IDE for development

Thanks in advance

Done similar things with available deflate()/inflate() routines. Also possible to create ZIP headers and directory records around uncompressed data.

​

Could probably craft a demo on the F4 platform, what are you offering?​
