Flowcode Support Board

External code can be included in Supplementary Code. See: https://www.flowcode.co.uk/wiki/index.p ... ntary_Code

Instead of adding the code directly to Flowcode, add statements into Supplementary Code such as the following to point it at external files:
You can then call any external C functions in your code by adding a C icon to your Flowcode macros.

Created an another component using AI for ESP32 that a single macro call enables direct email dispatch via SMTP (SSL/TLS) for simple notifications like sensor reading or system alerts. Ensure that ESP32 has an active WiFi connection before calling the macro.

Input Parameters
HOST_ADDRESS: SMTP server (e.g., "smtp.gmail.com").
PORT: SSL/TLS port number. (465 for Gmail)
USER_NAME: Full sender email address. (e.g., "yourname@gmail.com")
PASSWORD: 16-character Google App Password (e.g.,"xgdihlrtexusksta") not login password
DESTINATION: Recipient list (e.g., "a@mail.com, b@mail.com")
SUBJECT: The title of the email. (e.g., “Temperature Alert")
MSG_LINE 1 - 4 : Four lines for your data strings (128B per line)

Please note that I have specifically tested this component only on the ESP32 Wroom 32 module with Gmail account

That's very neat, thankyou.

One suggestion - if you have a string as a parameter to a macro - untick the 'make local copy' check box - this saves duplicating the string (which takes time and memory) - and you can then pass strings of any size.

So - you could have string msg_text[10000] as the parameter to the function - and this is just passed as a 32bit pointer (and a length FCsz_MSG_TEXT) - if the 'make local copy' is ticked it will copy the string to a local (10000 byte) buffer - but otherwise doesn't.

Hi

This sounds a very cool component. Thank you for creating and sharing.

I hope to test it for myself soom.

Regards

Hi Everyone,

Sharing here an another component for ESP32 that allows users to configure Wi-Fi credentials and up to 15 custom parameters
(like API keys, IP addresses, E-mail address, URLs etc) via a mobile-friendly web browser.

That looks very professional well done and many thanks for sharing.

Would you mind if we took it and made it into a component that's part of the package?

Hi Ben and Bijumon

It would be great to have something like this as an official component. Whilst the idea of scanning for WiFi etc isn't new I particularly like the custom options as Bijumon suggests to enter your api-key or similar. Such an obvious and great idea, one that surely makes us all think "why didn't I think on that"?

This would make any User Interface much more friendly and helps to provide a stand alone product that doesn't need hard coding.

Regards

Hi Ben, chipfryer27

I am incredibly honored by your interest! I would be absolutely delighted to see this integrated as an official Flowcode component.
As a hobbyist, I’ve always enjoyed pushing the boundaries of what I can build.
This project was a collaborative effort of my vision and AI Gemini, which helped me create the C-code and CSS.
I have updated the code include a Restart Device and Back to Setting button features.
I am really looking forward to seeing this as an official component in Flowcode

Warmest Regards

Hi Everyone,

custom fields Buffer Overflow Fixed.
Added a "Dark" and "Light" mode toggle.
Added a Base64-encoded png custom logo.
Added spinner on WiFi scanning button.
