I have been having difficulty compiling or uploading code for esp01 module, I keep getting this error
Please help
The message means, your sketch is too big and will not fit into the flash.
There are two versions of the ESP01: 512kB / 1M Flash.
Which module do you have and what is the content of your platformio.ini?
Please post file content and error messages as code blocks instead of screenshots!
