TCA9548::disableChannel(uint8_t channel) is not working as expected

[pghj]

I think disableChannel was copy-pasted from enableChannel, but the condition !isEnabled(channel) was not inverted by mistake.

Thank you for catching,
definitely a (copy paste) BUG.
Will fix asap, probably tomorrow.

[pghj]

Thanks for the quick response.
It seems to me that the check can just be removed from both methods, because setChannelMask already tests the entire mask for changes.

Oops wrong button.

Good idea, would simplify code a bit.
Will create a develop branch asap to prepare for a 0.3.0 version.

Propose code
would also return false if the writing to the multiplexer failed.

bool TCA9548::enableChannel(uint8_t channel)
{
  if (channel >= _channels) return false;
  return setChannelMask(_mask | (0x01 << channel));
}

bool TCA9548::disableChannel(uint8_t channel)
{
  if (channel >= _channels) return false;
  return setChannelMask(_mask & ~(0x01 << channel));
}

@pghj
Develop branch created, build-CI is running.
Some more edits were made.

Looks good. Can you also make it return the result of setChannelMask when calling selectChannel?

Will check after lunch

@pghj
Do you have time to test the develop branch, otherwise I will merge it (as I see no issues for now).

[RobTillaart]

@pghj
I merged develop and released 0.3.0 .

Again thanks for reporting the issue!
