I'm sure I'm doing something wrong but I need some help to understand what.
I hooked the WS2811 LED string as in the video at http://www.espruino.com/WS2811. White to GND, red to BAT and green to B15.
I connected a battery to the white battery plug. This might be the problem because it's a power pack made by 4 1.2 rechargeable AAA batteries, so it's 4.8 V instead of 5 V. However the LEDs are powered because they briefly flash when I put the red wire into BAT (but they do that even if the battery if off.)
This is what I type into the Web IDE.
No LED lightens up. I tried to send the commands to the Espruino in the white part of the IDE, no success.
I tried a different baud rate of 6400000 because I read on the forum that not all the LED controllers might work with 3200000, but nothing change.
Is the 4.8 V battery the culprit? I don't have a 5 V one but I'm thinking about flashing a loop into the board and powering it with a 1 A/5 V Samsung charger into the micro USB port. Is that OK or it will be too much for the board?
Thanks.
