| xobs | What's going on? | 00:03 |
| CarlFK | trying to figure out how to read touch pads in python | 00:03 |
| xobs | Well, "touch" isn't implemented really. Someone needs to come up with a proper captouch library. But you may be able to fake it. | 00:04 |
| CarlFK | I'm looking at how Adafruit's did if for the CPX board | 00:04 |
| xobs | The touch pads are exposed in the DigitalIO module. | 00:04 |
| CarlFK | what / where is DigitalIO | 00:05 |
| xobs | In particular, the code is available at https://github.com/xobs/circuitpython/blob/fomu/ports/litex/common-hal/digitalio/DigitalInOut.c | 00:05 |

| tpb | Title: Digital Inputs | CircuitPython Basics: Digital Inputs & Outputs | Adafruit Learning System (at learn.adafruit.com) | 00:05 |
| xobs | You can try setting it to an input and reading it. As a hack, you can try setting pin T1 and T4 as output, with T2 and T3 as output set as "1". That might give you something that'll vaguely work. | 00:06 |

| bjonnh | the litex whatever approach | 00:10 |
| xobs | bjonnh: that's a great test harness to develop a "real" captouch module. | 00:16 |

| bjonnh | xobs: there is something I don't know in what I did | 00:24 |
| bjonnh | I'm using a digital input no? | 00:24 |
| bjonnh | tbh it is pretty sensitive and somewhat reliable | 00:27 |
| bjonnh | didn't try with CarlFK sticky fingers | 00:27 |
| xobs | It depends on a lot of things. Humidity, how shielded your home wiring is, things like that. Most of the work of a real captouch library would be to filter that out. And get things like field-effect detection. | 00:28 |
| xobs | Not that I'd recommend copying it directly (it looks like it may require an external pullup, and I don't know how good it is), but Lattice has a reference design at http://www.latticesemi.com/en/Products/DesignSoftwareAndIP/IntellectualProperty/ReferenceDesigns/ReferenceDesign03/CapacitiveTouchSenseController.aspx | 00:38 |

| CarlFK | xobs: did anyone make a tomu/fomu ubikey thing yet? | 00:40 |
| xobs | CarlFK: not that I'm aware of. | 00:41 |

| CarlFK | kinda - part of the tomu origin story was "$50 for a ubikey!!?" | 01:11 |
| CarlFK | so a little surprising there isn't something already | 01:12 |

| suchende | hello folks, I'm struggling with the dfu releases for the foboot. How do I do this with the dfu-util? Only the updater.dfu or first the updater.dfu and then the foboot.dfu file? | 16:15 |
| xobs | suchende: just the updater. foboot.dfu is used more to test it first, or to get the benefits of foboot-2.0 without permanently installing it. | 16:16 |
| suchende | Ok, thanks | 16:17 |
