I2C problems?

[kfricke]

I do stumble across sporadic I2C OSErrors:

Code: Select all

OSError: the requested operation failed

They do occur after not reproducible times and always do yield from I2C send commands. I can see them with my SSD1306 displays and some sensors (MCP9808 and HDC1008).

Initially i did believe the issue #1765 had to do with this, but i do use today's firmware on my WiPy. And tbh I do not even know if that has influence on the CC3200 platform.

Should i try to file a bug report or is this a already known issue i could contribute to?

Hi!

Please file a bug report as until now there are no known issues with I2C.

Thanks!

Cheers,
Daniel

Can you check if this still persists on the latest release: https://github.com/wipy/wipy/releases/tag/1.2.0 ? Thanks!

I will try to find some time during this week's workdays. But by the weekend you will get my feedback.

Sorry Daniel, but the recent builds are still trowing the same OSError after a random amount of iterations of sensor readings (36 to 327 over 12 tests). I did try the following firmware versions:

Code: Select all

MicroPython v1.6-89-g440d33a on 2016-02-27; WiPy with CC3200

and

Code: Select all

MicroPython v1.6-93-g8a18084 on 2016-02-28; WiPy with CC3200

From my perspective nothing has changed.

Hi !

I got the same problem with I2C and OSError - please try to solder the data and clock line and
tell me if the problem is solved.
