| 16:08.27 | schneider | Stormwind_mobile: uh |
| 16:08.53 | schneider | Stormwind_mobile: i think you can create accounts again, if that is what you were referring to |
| 16:09.15 | schneider | do you have an account on https://git.card10.badge.events.ccc.de already? |
| 16:09.32 | schneider | You should be able to raise a merge request against the hardware repository |
| 16:10.14 | schneider | mdik_: BSD |
| 16:10.22 | *** join/#card10badge msvb-mob (~msvb-lab@monero/hardware/michael) |
| 16:11.25 | schneider | or BSDish? |

| 16:13.30 | schneider | mdik_: i assume you integrated the menu module? |
| 16:13.58 | schneider | mdik_: i'm working on getting the original exnostat MR into a mergeable state |
| 16:14.22 | schneider | (basically doing a rebase and checking if functions need documentation) |
| 16:16.47 | schneider | Stormwind_mobile: and yes, reviewing changes to the schematic is rather hard and error prone :/ |
| 16:18.10 | schneider | if at all possible i usually try to create commits which can be understood by reading the source files |
| 16:18.27 | schneider | but that is not always possible even when trying to specifically do so |
| 16:18.55 | schneider | It gets even harder on with the layout. essentially one has to xor gerbers... |
| 16:19.39 | schneider | sad that frigginglorious is not here anymore :/ |
| 16:20.44 | schneider | I think it is not very hard to add some custom sensor streaming via BLE. It needs modifications of epicardium though. And it would likely not make it into the main branch ATM... |

| 19:41.16 | schneider | I was contemplating how we could maybe make the "main menu" button some kind of "app menu" button with a way to exit to the main menu in the future. I think that might go in a similar direction. It sounds like that could also need some kind of "lock" functionality like phones (used to) have. |
| 19:41.36 | schneider | if people have an opinion/idea for that, would be nice to hear |
| 19:43.12 | schneider | or maybe some other way to make that button useful in applications |
| 19:44.04 | schneider | so far it serves as a sure way back into the menu, even if the app crashes in weird ways |
| 19:44.55 | schneider | I was mainly thinking about it because i wanted to make use of all four buttons for the HID over BLE usecase |
| 20:21.37 | Stormwind_mobile | schneider: How much do you/we know about the Sensor Fusion firmware? Do we have access to the source code and build environment? |
| 20:23.22 | Stormwind_mobile | The BHE160 provides a hardware interrupt signal, and it's also connected to the SoC. So it could serve as another virtual button, correct? |
| 21:04.10 | schneider | sadly almost nothing |
| 21:04.39 | schneider | if we want another button, the BMA400 is probably better suited |
| 21:04.50 | schneider | it has tap detection built in |
| 21:05.28 | schneider | it is much lower power and meant to be off limits for the app |
| 21:09.54 | Stormwind_mobile | Oh, its BHI160 |

| 23:42.18 | Stormwind_mobile | So my phone silently died in the process of composing the follow up message, and I became lost in reading datasheets. |

| 23:51.13 | Stormwind_mobile | Both BMA400 (just accelerometer) and BHI160 (9dof sensor fusion IMU, incomprehensible magic unit) feature interrupts which are wired to the SoC. |
| 23:51.14 | Stormwind_mobile | The BMA400 can detect e.g. attitude changes, steps, taps and such, also has a temperature sensor. I guess the control logic is more or less a state machine with a lot of register settings. |
| 23:51.14 | Stormwind_mobile | The BHI160 in turn contains a complete 32bit SoC, with firmware, patchable in RAM, API, drivers for Android and some other OSs, way more complex. But it can also detect more complex gestures, e.g. the "glancing at the watch" motion, while the main SoC is sleeping. |
| 23:51.14 | Stormwind_mobile | I haven't played with the G-Watch app, yet, but I suspect that it constantly interacts with one of those two sensors, which eats up more battery life. So there's potentially some value in doing this interrupt driven. |
