esp8266 busio pin check error #134

Closed jerryneedell closed 7 years ago

jerryneedell commented 7 years ago

on an esp8266 (Huzzah breakout) When initializing busio.I2C it returns an error for Pin DVDD "in use"

to replicate execute:

from board import * import busio bus = busio.I2C(SCL,SDA) generates: ValueError: Pin DVDD in use

Hi @jerryneedell, I can't reproduce this on the feather version. I'm using 0.10.1.

Adafruit CircuitPython 0.10.1 on 2017-05-20; ESP module with ESP8266
>>> from board import *
>>> import busio
>>> bus = busio.I2C(SCL, SDA)
>>>
>>>
PYB: soft reboot
#5 ets_task(40100164, 3, 3fff839c, 4)
boot.py output:

Press any key to enter the REPL. Use CTRL-D to soft reset.

Adafruit CircuitPython 0.10.1 on 2017-05-20; ESP module with ESP8266
>>> from board import *
>>> import busio
>>> bus - busio.I2C(SCL, SDA)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'bus' is not defined
>>> bus = busio.I2C(SCL, SDA)

Any thing I missed? Does it still repro for you?

Odd - I was using a "non-feather" ESP8266 Huzzah - in case that makes a difference. I try both when I get home later this afternoon.

I guess you fixed it ... ;-) I can't reproduce it now either. Sorry ... Feel free to close it, I'll repost it if/when I can reproduce it. - I hate problems that just go away. They usually reappear at the worst possible time ... I tested it on both the feather and breakout boards.

No worries! I'd rather have an issue filed that goes away versus not hearing about something at all. Thanks again @jerryneedell! Reopen if it happens again.
