pycom.heartbeat

[Lokefar]

Unsure if it is a bug or a choice but as fare as I can see it is only possible to use the heartbeat function with the color blue?
I could see applications where it would be nice to be able to change the heartbeat color.

@Lokefar

firmware blinking blue indicate that all is ok
firmware state red indicate problem..
than changing "defaults" firmware colors are not avaiable

[Lokefar]

@livius I get that. I can turn the light on with a color without problem. My suggestion was that it was made possible to change the color of the heartbeat function (ie. the blinking light/firmware blinking). That way I wouldn't have to write a function for blinking lights but could use the one already in the firmware.

@Lokefar

pycom.heartbeat(True)

turn on fimware blinking - do not use it if you do not need default firmware state indicator only own one

on start do

pycom.heartbeat(False)

and after this you can turn color by typing

pycom.rgbled(0x007f00)

@livius Just ran this code via the REPL:

>>> pycom.heartbeat(True)
>>> pycom.rgbled(0x007f00)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OSError: the requested operation is not possible

As fare as I can see I have the latest firmware version.

@Lokefar said in pycom.heartbeat:

pycom.heartbeat(False)

it work for me

pycom.rgbled(0x007f00) # green

i have many state indicator in rgb led color like pink, orange ..
And it work for me - do you heve latest firmware?

did you do first disabling firmware blinking as mentioned in the first post?
pycom.heartbeat(False)

[Lokefar]

@livius I am not sure I understand your answer? I know it is possible to change the color of the LED with the

pycom.rgbled('color')

command, but as you can see in the traffic light example that is with

pycom.heartbeat(False)

My question/comment was that the heartbeat don't seem to work with other colors than blue.
