does not work with Raspian Jessie? #6

Closed Sispheor closed 8 years ago

Sispheor commented 8 years ago

It seems something changes ioctl message structure. See https://wolfgangklenk.wordpress.com/2015/10/25/spi-communication-issues-with-raspbian-jessie/

Also: https://github.com/mxgxw/MFRC522-python/issues/29

Looks like an upstream issue between kernel (raspberrypi/linux#1547) and SPI-py (https://github.com/lthiery/SPI-Py/issues/17)

@Sispheor doesn't look like it's related to ioctl and the article you linked was from Oct 2015. I had this working for me in Apr 2016 on Jessie.

Yes, the first article is outdated. And Yes it was actualy an issue in SPI-py. Thx for your answer.

So it's needed to use custom SPI-py with the cs_change set to 0, do I understand this correctly?
