| Dec 8, 2015 at 23:10 | comment | added | Ghanima♦ | @SteveRobillard, I withdraw my first comment, per rpi.blog Stackable HATs featured in the specification discussion – but eventually it was thrown out due to the large increase in complexity of autoconfig and potential for user error. | |

| Dec 8, 2015 at 23:05 | comment | added | Clare Macrae | @Ghanima I would be really happy to solve this for the one-HAT case, and not worrying about stacking them! | |
| Dec 8, 2015 at 23:04 | comment | added | Clare Macrae | @SteveRobillard Thank you for the suggestion. I've clarified my question to try to say why setting environment variables (and any other keyboard interaction) won't work. I hadn't heard of dmesg and lsusb. Googling them pointed me to Know your Raspberry Pi which looks good too. | |
| Dec 8, 2015 at 23:04 | comment | added | Ghanima♦ | @SteveRobillard, do all the hats come with an eprom? Are they not stackable? If so how are the then multiple eprom addressed separately? | |

Clarify need to avoid running commands e.g. setting environment variables
|
| Dec 8, 2015 at 22:53 | comment | added | Steve Robillard | I think this is possible with hats, since they contain an eprom used for setup. You can probably determine the rest with some shell scripting and looking at what is reported by dmesg, lsusb etc. You may also want to consider setting an environment variable that you change when you swap hardware. | |
