Re: WeMos D1 Mini Lithium Battery Shield (HCWEMO0009)

Hi,
Do you know if this acts like a backup battery so if I power the D1 from the USB connector it provides 5 V to the D1 and charges the connected battery at the same time and if I remove the USB power it still provides 5V to the D1 from the connected Battery?

Re: WeMos D1 Mini OLED Shield (HCWEMO0007)

Thanks, the sketch now compiles without errors but I've not tried flashing yet, I'll let you know if it works OK.

Re: WeMos D1 Mini OLED Shield (HCWEMO0007)

Hi, Just received the OLED screen and getting errors when compiling the test sketch. I'm compiling other ESP8266 sketches without any problems.

Re: Digitally controlled 8x RGB LED Light Strip (HCMODU0075)

Thanks, that fixed it. One other thing I tried was to add a lesser intensity red LED trailing the moving one, but when the LED changed direction the LED at the end flashes green or blue. /* Step forward through each LED */ for(index = 0; index < NUMBEROFLEDS; index++) { HCWS2812.ClearBuffer(); RGBBu...

Re: Digitally controlled 8x RGB LED Light Strip (HCMODU0075)

Yeah its's a pretty simple setup so not a lot to get wrong. I does sound like a timing issue. The timing constraints of the data signal is very tight and it has to be tuned for the different types of microcontroller on different Arduino boards. I'll try and find some time today to download the libr...

Re: Digitally controlled 8x RGB LED Light Strip (HCMODU0075)

Odd, it should work fine with both. Did you try it with the first example (Cylon_Example) in its unaltered form? That sketch should defiantly work. Tried both cylon and random examples in their unaltered form and both just turn on all LEDs white...??? I would say I'm doing something wrong but when ...

Re: Digitally controlled 8x RGB LED Light Strip (HCMODU0075)

By default the LEDs shouldn't turn on unless they are told to do so. So it would suggest your pro min is sending something to them, just not what is expected. Are you by any chance using the 3.3V version of the pro mini? As a side note, it's not important for the value of NUMBEROFLEDS to exactly ma...

Re: Digitally controlled 8x RGB LED Light Strip (HCMODU0075)

Just connected up to a Mini Pro and all the LEDs just come white, I changed the define NUMBEROFLEDS in header file to 8 first.

Any ideas what I may be doing wrong?

Cheers
