Update buttons example script for PaPiRus Zero #54

Closed digithree closed 7 years ago

digithree commented 8 years ago

Add command line options to switch button pins to PaPiRus Zero mapping. Use -z or --zero to activate. Defaults to standard mapping

Hi @digithree , thanks for this. could this not be automatically done by checking if it is a HAT or not in the case of the Zero? Maybe by looking at I2C. If that's not the case could you also provide a "usage" description for the main README.md?

shawaj commented 7 years ago

Could definitely be done by checking for the HAT EEPROM.

Or alternatively looking for the RTC

Hmm, I'm not sure how to do that. Could you point me in the right direction?

shawaj commented 7 years ago

If it's a HAT you should have a value of Pi Supply in /proc/device-tree/hat/vendor and PaPiRus ePaper HAT v1.8 or v1.9 in /proc/device-tree/hat/product

You can find them by putting "cat" in front of the address.

And also if it's a HAT you should have something connected to address 0x6F on the I2C bus. That's the RTC.

Thanks

See my PR #79 which implements Aarons (shawaj) suggestion for HAT detection.

francesco-vannini commented 7 years ago

This has been sorted already in #77 and #79 so closing this PR

digithree commented 7 years ago

That's fine, glad it is apparently sorted. I'll check it out soon.

shawaj commented 7 years ago

Thanks for your code though
