I almost got a bit worried, as I didn't see an entry from you yet, but you made it, yay! :Thmbsup:

I like the simplicity of the design :Thmbsup:

There are a few small remains of Greeting Card List though:
- 'Who is the Card for' column title
- 'Who is this gift/card for?' mouse-hover text

And 1 remark: The list is alphabetically sorted. That's fine, but to keep my designated order I have to add numeric prefixes. A note indicating that would be nice.

NANY 2022 Entry Information

Application Name Dotmatrix display support for ESPEasy
Version 2021-10
Short Description Use 8x8 dotmatrix displays to build a tickertape display
Supported OSes ESP8266/ESP32 microcontrollers
Web Page ESPEasy documentation for the plugin
Download Link Github releases page for ESPEasy (use the DISPLAY build)
System Requirements
  • ESP8266 or ESP32 microcontroller (best get one with min. 4MB and USB support on board for easy connection)
  • Dotmatrix displays based on MAX7219 chip
  • Level converter 3v3 - 5V
  • Proper power supply
Version History
  • Included in the ESPEasy release build since October 2021
Author Ath

I've been helping with some development on the ESPEasy platform, a firmware for ESP8266/ESP8285 and ESP32 WiFi enabled microcontrollers, for some time. (See also my entry for NANY 2021)
By request on the ESPEasy Github issue tracker, there was a desire to add support for dotmatrix display using the MAX7219 chip.
I found an open source Arduino library that has quite extensive support for these chips/displays, called Parola, that offers some fancy features for displaying all kinds of information on such displays.
After some investigation, I found that, with some work, I could add that as a feature to ESPEasy.
The hard parts were in a) getting the library to work with ESPEasy without triggering watchdog resets, and b) designing and building a usable UI for configuration.
a) was solved by adding some 'yield()' calls, allowing for background tasks and the watchdog to process as needed.
b) was solved by getting feedback from other developers on the project :)

  • Display text, with several effects including a tickertape style, on groups (zones) of such display modules
  • User defined zones from 1 to 254 of display modules
  • Use of variable content, like date/time, or measured values like temperature etc.
  • Brightness control per zone
  • Draw bar-graphs on groups (zones) of displays
  • Address separate pixels of each display
  • Repeating content display

Planned Features
Any reasonable request that comes in ;)

A group of displays showing some different content:

Display contents:
  • Date (DD-MM) with animation
  • Date (YYYY-MM-DD) with animation (scroll left, in progress)
  • Clock (24h), updated every minute, no animation, no flashing colon
  • Date/Time (YYYY-MM-DD HH:mm) with animation (scroll left, in progress)
  • Bar-graph with 3 bars, type 2 (single line) mimicking temperatures (-14, +4, +26) on a +40 to -20 (left to right) scale and a zero-point around 1/3rd from the right (the left module reflected weirdly in the photo, but it does work)
  • Text (ESPEasy is great fun!) with animation (scroll left, in progress)

Top-right is a 'proper power supply', as these displays can use quite some current when many LEDs are lit.
Bottom-left is the ESP8266 controller (a Wemos D1 mini clone)
Between the controller and the bottom display is a level converter for 3V3 to 5V.

The configuration of the zones: (from the documentation page, linked above)

(For details best visit the official documentation page)

  • Download the latest ESPEasy release from the Github releases page.
  • Extract the entire .zip file in an empty folder
  • Start the ESP.Easy.Flasher.exe (Windows) or get the esptool flash tool for other OS-es)
  • Select the .bin file with 'DISPLAY' in the name (either ESP8266 or ESP32, depending on the controller used) or 'MAX' when using an ESP32 with 16 MB Flash
  • Upload the .bin file (for ESP32 initially the '-factory.bin' should be used) to the controller.
  • After successful completion, reset the controller
  • Connect to the WiFi Accesspoint exposed by the unit (ESP-Easy, ESP32 or MAX-ESP32), password 'configesp'
  • Enter the credentials for your WiFi network the ESP controller can connect to (2.4GHz only)
  • Find the ip-address of the using, either by looking at the log available via the USB serial link, your WiFi router or network scanning tool
  • Open a webbrowser with the ip-address to the unit to configure the device
  • On the Devices page add the 'Display - MAX7219 dot matrix' plugin to the task list, give it a name, and configure using the documentation
  • Connect the hardware as suggested in the documentation
  • Enable the plugin, and enjoy the display :D

Disconnect the device.
Install another firmware on the controller.
Delete all downloaded and extracted files.

Use a decent power supply to power the displays!

That should be possible using the Scrolling Window caption, but then select the Manual mode. There are some tutorials available, created by Mouser, but I've never used them, as I've been using these scrolling captures for ages, I know what to do 8)
Does have a little learning curve, but it works like a charm.

Well, then not unimportant: Do tooltips work in other applications?, as there is a global Windows setting that is possibly messed up :tellme:

It is working fine over here, so don't know why it shouldn't work on your system. Do you run SSC As Administrator, by any chance? Or have software active that changes the behavior of the mouse? These may interfere with showing tool-tips.

Obviously rtila is better, but for me is enough with this now.
Well, as usual with your questions, the solution you choose doesn't have much to do with the question you asked >:(

How does this:
At the present moment i am happy with email grabber, Only collects email in the most simple way.

Align with the original request in any way ? :
I would like a software able to find data in the web :

What type of software is this and what are the best. Better is free.

A couple of days in and VSCode 1.62 has a 'fix' for the issue, by default showing those UTF directional attributes as just that, without interpreting them. And that can be turned off, if desired :up:.

Is that application written in Delphi, by any chance? Especially when using older Delphi versions, applications can behave quite strangely on window 'visibility' to other applications.

Screenshot captor does it's ultimate best to try and scroll a target window with any means it has available, but still it doesn't succeed in all situations. Then indeed the Manual method is the solution. It just depends on the way that application is built.

The first question was the other way around; Is your screenshotcaptor running with administrator rights by accident? In that way it can't intercept the hotkeys from your normal windows user-session.
