    • ESP8266_ESP32_REST_API

      Re: 0302-11_ESP8266_REST_API_example

      Hi all,

      I factually succeeded to use the ESP32 with a digital Temp. / RH sensor connecting to my Raspberry Pi.
      However I'm wondering if I also would easily be able to get a kind of "Status" signal from the ESP32 (created in the Sketch) that is giving me feedback if there was a reply received, just like a "Modbus connected" signal.
      If the ESP32 is no longer updating the various parameters because there is no communication anymore, it would become handy to be aware of it.

      I assume it would not take much programming in the sketch, but so far I'm not vary familiar with the arduino IDE programming of an ESP32 (or ESP8266).

      Any feedback would be appreciated.

      Regards,
      Peter

    • Comparing 2 strings

      I'm looking for a function block comparing two strings and generate a logic output of "1" when equal and "0" if NOT equal.
      But I could not find a string function block that is doing that. I noticed the STOR block and tried to convert to real and compare the real values, but the output of the STOR block is always "0" so when comparing that with another string that was converter to Real is not working.
      I guess I might have overlooked another function block that I need for this purpose.

      Any feedback on this will be appreciated.

      Best regards,
      Peter

    • Replacing typed characters for "***" while typing a password

      Hi,

      I"m wondering if there is an example how you can replace characters when typing. Like you do for many websites when entering a password.
      So I want to use a typed string from the HMI in the "task" block, but want to replace the typed characters with "***" characters.

      Looking forward for feedback on this.

      Best regards,
      Peter

      Hi Tomáš,
      Excellent, did not thought about doing it in that way, but that is exactly what I was looking for. Thanks a lot!

    • Displaying a Text in HMI by digital signal

      I'm wondering if there is an easy way to "hide" or "diplay" a piece of text in the HMI Designer based on status of a digital signal (binary signal) like a push button or a LED that indicates the status of the digital signal in the "task block".
      So if a status is "ON" in the task block, I would like to display a "text" in the HMI and if it is "OFF", it should be hidden.
      I can use the "hide_by" function of the "DisplayString" component, but that requires to define the text to be displayed within the "task block".

      Alternatively if you take just a "Text" from the left hand side menu (i typed "My text"), and create a "group", you can add some "group functions" to it, but that does not include the "hide" functionality. I might be able to use the "Opacity" function and use a value of 0 and 100 to either display it or hide it, but I thought there might be an easier way that I simply did not figure out yet.

    • dygraphOptions adding additional Y-axis

      Is there any example available that I could not find so far where a second or third Y-axis was added to the trend plot?
      When using signals that are significant smaller in size compared to others, it would be nice to separate them on different Y-axis (either on left hand side, or on right hand side of the trend plot area.
      I can find examples on this website: http://dygraphs.com/tests/two-axes-vr.html but don't know how to achieve this in Rexygen on trend plot under Options.
      So when using a trend plot with 10 series, how to make sure that series 1, 2, 5,6 and 8 belong to Y1, series 3 and 7 to Y2 and 4, 9 and 10 to Y3 for instance?
      The dygraph trendplot tool is a great and powerfull thing, but the documentation when using this in Rexygen can use some more details I think.

      Regards,
      Peter
