Auto calculate sketch size correctly #86

Closed sticilface closed 6 years ago

sticilface commented 6 years ago 
DATA:    [====      ]  44.2% (used 36232 bytes from 81920 bytes)
PROGRAM: [=         ]  10.7% (used 450796 bytes from 4194304 bytes)

I'm assuming that the 4194304 comes from linker or something, however, it is misleading as the max sketch size is 1Mb (so on the 4Mb module 1Mb sketch + 3Mb for SPIFFS). However, I believe this decreases to 512K with OTA as it needs space for both bins at once so it is 512 + 512 + 3Mb. The Arduino environment env doesn't get this right either.. see below

Sketch uses 412828 bytes (39%) of program storage space. Maximum is 1044464 bytes.
