    • RE: Is Wifi Direct available for any of the M5Stack esp32 devices?

      @zontex Thanks. Hopefully this will be soon. Especially useful for controlling devices via smartphones.

      As the title says. Is Wifi Direct available, now or in the future?

    • RE: Control first LED on neopixel strip with FastLED with M5Stack

      On Arduino using the M5Stack (in my case the Gray version) pin 21 is the pin to pass on to FastLed. For M5StickC it is pin 32.
      That the M5Stack shows a bright white light for the first LED seems to occur when one also uses the M5.Power.begin() command.
      This piece of code should work on both devices adjusted for the device in use:

      //#include <M5StickC.h>
      #include <M5Stack.h>
      #include "FastLED.h"
      
      CRGB leds[15];
      
      void setup() 
      {
      M5.begin();
          FastLED.addLeds<NEOPIXEL, 21>(leds, 15); // M5Stack Gray
          //FastLED.addLeds<NEOPIXEL, 32>(leds, 15); // M5StickC 
      }
      
      void loop()
      {
          static uint8_t hue = 0;
          if (255 == hue)
              hue = 0;
          else
              FastLED.showColor(CHSV(hue++, 255, 50));
          delay(50);
      }

    • Control first LED on neopixel strip with FastLED with M5Stack

      Some simple questions:

      Controlling the LEDs works well, but how can I control the first LED? Most of the time it is a very bright white, but it can change.
      How can I use the strip on a M5Stick C?

    • RE: M5StickC and 18650C endurance

      @Pepsi Thanks, I could not find the call to decrease the speed. Not very much, but it helps.

      @liemph and @ajb2k3 Thanks. I ordered a few. It will take several weeks, but they will be useful. Also for other projects I am working on.

      @ajb2k3 said in M5StickC and 18650C endurance:

      kewize

      Can you be a bit more specific? I can not find any information with that name.

      @liemph Ah, nice device. Been searching the internet and found one brand with interesting devices (even with blue tooth data gathering) but the shipping costs are ridiculous. Could you tell me what brand you have. Makes searching less difficult.

    • RE: M5StickC and 18650C endurance

      @crami25 . Thanks for the video. Could be useful for another project I am working on. But for this I can not let an elderly person remove the battery for charging as Pepsi wrote.

      @Pepsi I can not find anything on corespeed. How did you lower this? Maybe this will give just enough endurance.

      @liemph Thanks. I did a number of simple tests and got rather varying results. Ranging from 8 to 22 hours (only once), but mostly around 12 hours, but with large charging times indeed. I also used two different charging devices. How ever I would like to measure these values (charging and discharging) for better tests, but not on the screen. I want to send them using the BLE I already use. Could you share with me how you read these values.

      @Pepsi BTW, how much time does it take to fully charge the battery? Does probably depend on the charger, but just to have an idea.
