- Mon Nov 16, 2015 8:58 pm #34249 To use the SPIFFS (SPI Flash File System) follow the instructions below, these are simple put the extracted file in the directory as instructed then an extra tool appears in the IDE "Tools" menu.
The data (files to be loaded to Flash, webpages + pictures etc.) is stored in a "data" folder in the sketch folder.

This is one of mine........

Some useful interaction with LCD and SPiffs to get 40 chars on a 16 char screen for both lines.......
This is a bit ugly but the conversion of data type is demonstrated.

- Sat Nov 21, 2015 6:52 pm #34649 Hi @GengusKahn,

I cant seem to find the example I think you posted for NTP time in to variables, wanted to check NTP to see if a date and time has passed and then to trigger an event.

Did you post something like this?

Cheers mate

Thank you buddy, I have hacked your code a little and can extract the hour/min and second in to int variables from google awesome. This alleviates NTP dedicated library etc.

Many thanks for this It will be a breeze now to schedule events based on time and day. I will post a simple example for others once I have a tidy version

Cheers mate, keep publishing your great work.
