Would love to get this going ..... looks like a lot of time going into this.
Tried all sizes of flash just in case there was an issue there.
Using ESP12 ..
Sure.. can get the gpio sample working ... but saving and recalling fails. In station mode even less friendly....
Lots of .....

Any clues would be really appreciated.
Edit
Ok.. start afresh (a few times) - even format at times.... get it so that it cant open the four files (so must be empty) .... save a " ports" file, a copy of the gpio example. Write a blank title file ... just cls and load ports . Save it. Sometimes ports file will open again sometimes not. Whilst in edit frame mode, all can run well.
Reset and it's a no go. Can't open file, or can't open ports file and endless loop.
At start up it can appear that the two files have been opened, but won't actually open in edit mode.

Might be a clue to what is happening?

The file open msgs can be ignored.

For the esp-12 I would use the 4m flash.


When Wifi settings are saved the module must be rebooted for it to connect.

If you have a terminal opened at 9600 speed It should display that it was able to connect and its ip address on the network.

Network name is case sensitive.



There is an issue with all the extra blank lines when you reopen a program. You should delete the blank lines at the bottom for now before attempting to save the file again.

This issue is on the radar and will be fixed here soon hopefully.

Working on improvements to the editor.

Working out the java script to upload one line of the program at a time instead of the whole thing all at once.

Hopefully will be posting a new build here tomorow night.

Thank you for the info ....... Yes, deleting blank lines certainly helps a lot. Station mode has far less issues.
File saving etc no more an issue.
Getting resets at times, and can't get solid reproducible working, but far less frustrating. More fun, which is what it all about.
Please do not take these as negative comments, because they are definitely not, just notes as to what is happening.

Without this kind of development by someone who has the skills and share mindset to do it, we'd still be fishing with bamboo and string!
Looking forward to updates.
