Remote I/O Error

[C-D-Lewis]

Hi, I just took delivery of a shiny new (white!) enviro phat, and am having problems getting it to work.

I'm using a Pi Zero W:

processor	: 0
model name	: ARMv6-compatible processor rev 7 (v6l)
BogoMIPS	: 697.95
Features	: half thumb fastmult vfp edsp java tls
CPU implementer	: 0x41
CPU architecture: 7
CPU variant	: 0x0
CPU part	: 0xb76
CPU revision	: 7

Hardware	: BCM2835
Revision	: 9000c1
Serial		: 00000000e4780010
Model		: Raspberry Pi Zero W Rev 1.1

with apt-get update and apt-get upgrade all up to date, and I can see i2c devices attached when the phat is in place:

pi@raspberrypi:~ $ i2cdetect -y 1
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:          -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- 23 -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- 76 --

Yet, when I try and follow the tutorial, or run any of the examples, I get the same error:

pi@raspberrypi:~ $ python

IOError: [Errno 121] Remote I/O error

Am I missing anything or doing anything wrong? I'd love to get started with this module!

Is this repo still viable for the newer white version of this board?

[Gadgetoid]

Took me a second to realise what was happening, but I think you want this library over here -> https://github.com/pimoroni/enviroplus-python/

[C-D-Lewis]

@Gadgetoid Thanks for the speedy response.

As far as I know, I don't have the 'plus' version (https://shop.pimoroni.com/products/enviro?variant=31155658489939), but if this other library is still appropriate I will give it a spin!

[Gadgetoid]

Indeed, the other library still applies! I should probably add a notice onto this library to clarify that- since it's definitely not clear right now.

[C-D-Lewis]

Please feel free to close. A note in this repo's README pointing me in the right direction if I have the newer white board (whether or not it's a + edition) would be very useful, and I would have gone straight there :)

[Gadgetoid]

Have updated the README- hopefully sufficient! Thanks for forging the way for future lost customers.

[C-D-Lewis]

I used to write docs for a living - this is how these things get fixed. Thanks for the quick docs update 💪
