    • RE: Help Creating a Timer

      Hi Adie,

      Two comments.
      The accuracy of any timer at the 1/100th second level is difficult to assess. You would need a reference timer and connect the start and stop signal both to this timer and to the M5stack /ESP32 based on timer
      Absence of a sytem clock. Actually there is one M5 Core 2, its RTC but it reports only seconds, minutes, hours, days.. On the other entry level Core models, there is none but you can add an RTC units that will provide the functionality

    • RE: Help Creating a Timer

      Hi Adie,

      I don't think you are doing something wrong but there is not enough code to have a stopwatch
      and as you say you need to link the code to system time. As you want to measure quite small durations, I would recommend you use the function "Get tick ms" that is available from the Timer section. You need to read the value at the start of your timing operation and again at the end.
      By difference you get the duration. You then need to transform this duration in seconds, 1/10th and 1/100th
      Once you are there, you need to define the start and stop, button pressed or detection by a sensor

    • RE: M5Stack ENV III

      The sensor works right away under UI Flow. I don't have any experience with it under C++

    • RE: ENV III Causes CoreS3 to restart.

      A workaround is to use Core or Core2 with Env III and UI Flow
      No problem

    • RE: UI Flow 1.12.4

      Hi gavin67890

      Thanks a lot for the reply !
      However I am missing these snippets. Under Demo, I only have one submenu "Examples"
      Did you do something special to install the snippets ?

      There is at least one change. Env Sensor IV has been added.. But there may be other ones

    • UI Flow 1.12.4

      Just downloaded this version. Up to 1.9.9 there used to be a summary of the features brought by the new version. Could we have it again ? Or is it published somewhere else ?

    • RE: unable to connect to CO2L unit

      @mtylerjr Just tested the M5 demo example with my CO2 unit.. I don't have the L version, actually was not aware of its existence.
      After a first run the sketch reported errors, the demo program uses Ubuntu font that does not exist on Core 2 UIFlow 1.12.3... I replaced all the labels fonts by default and yes the sensor works on Core 20_1692954046604_CO2sensor.jpg

    • RE: Excessive variations of K meter readings

      Hi there,

      I am closing this topic. Actually the cause for these excessive variations was the 5V USB adapter I was using.
