disable some functions to save flash space #31

hi... i am a fan of your plugin, i use it daily xD

is there any way to disable some unused functions to save space to other stuff in sketch?...

for example, i never use ssl or udp and my sketch sizes about 95% of flash, i would like that free space to put a couple more commands, manual or web pages (telnet or http server)... currently i feel somewhat forced to get and put some sdcard module and library that will complicate and grow my config and sketch anyway

JAndrassy commented 3 years ago

95% is OK it doesn't cause problems, but SD library will not fit into that 5% remaining. the compiler optimizes unused code away. so udp and ssl doesn't take any place in your sketch if you don't use them. I assume logging is off.

i currently have an irrigation system configurable by telnet commands (with some man pages)... i would like to turn into an http server for easy usage, but http uses more text :(

anyway thanks for your time, response and effort

(still the best esp8266 library!)
