| 00:35.23 | DocScrutinizer05 | watch out! there's a pitfall with this: HNP defines active DIScharge of VBUS to basically transfer data over power. So huge buffer capacitors might be problematic even behind a 44R series resistor |
| 00:37.09 | DocScrutinizer05 | when in a chinese hub some big caps are not equipped, I'd first think of rithless optimization, but in this particular case maybe they even thought having them was nice and then noticed they actually spoil stuff |

| 04:12.50 | wpwrak | xiangfu: heya, did you see what i wrote on adjusting the threshold ? ("maybe start with 500 [...]") |
| 04:15.16 | wpwrak | in any case, things will be more fun once you have a real case. it changes quite radically how the device feels. |
| 04:20.56 | xiangfu | check the irc log |
| 04:22.47 | xiangfu | wpwrak: how to reflash the anelok-2014.bin. do I have to reflash the boot-bin first. then using dfu? |
| 04:23.25 | wpwrak | you should be able to use dfu directly. you already have a good boot-2014.bin, from the combined binary |
| 04:24.07 | wpwrak | (the combined binary is really just what the flash of anelok looks like when you first flash boot-2014.bin and then dfu anelok-2014.bin) |
| 04:26.12 | xiangfu | when I plug the anelok. the led was on. like for 1 sec. then off. from the dmesg. the usb got disconnect. |
| 04:26.21 | xiangfu | so I should using dfu when the led was on? right? |
| 04:27.31 | xiangfu | YEAH |
| 04:27.39 | wpwrak | ;-) |
| 04:28.53 | wpwrak | you can use "make update" to make this more comfortable: "make update" prepares the transfer, then waits for anelok to enumerate. then you can reboot or reconnect anelok, and the dfu will start automatically. |
| 04:34.29 | xiangfu | great. |
| 04:56.36 | wpwrak | just added two new parameters to devcfg: "scale", which is the scaling of the touch values, and "offset", which is an offset that's added to the scaled value |
| 04:58.08 | wpwrak | so if the slider doesn't want to move all the way to top and bottom, increase "scale" (default: 96). if it moves too quickly, decrease it. and if the center seems to be way off, adjust offset (default: -10) |
| 05:08.31 | wpwrak | and a twist: if you set the offset to 0, then it'll pick the default value since 0 is used internally as "not set". fortunately, nobody would notice a small difference in the offset, so one can just use 1 or -1 in this case. |

| 05:29.43 | xiangfu | the cursor flickers quickly. update the thresh from 400 to 100 |
| 05:29.49 | xiangfu | now ... |
| 05:30.23 | xiangfu | hmm... the anelok take like 2 mins to boot. |
| 05:31.08 | wpwrak | you mean the time between a reset and until it responds touch input ? |
| 05:31.28 | wpwrak | responds TO touch input |
| 05:33.57 | xiangfu | Yes. |
| 05:35.27 | wpwrak | yeah, that's the time it takes for the calibration to settle. the rest of the system is up and running almost instantly, but it takes a while until it understands the touch input |
| 05:36.09 | wpwrak | and the time should be more like 30 seconds. just make sure you don't touch the sensor during that. |
| 05:36.47 | wpwrak | lemme try to add a fast initialization. probably won't work (i've tried it before), but let's see ... |
| 05:44.02 | xiangfu | we can make the led one until it finish setup the touch input. |
| 05:44.22 | xiangfu | hmm... threah = 50000 right now. the cursor still blinking. |
| 05:45.22 | wpwrak | wow. that's weird. |
| 05:46.10 | wpwrak | at 5000 i would expect the thing to be quite dead :) |
| 05:46.37 | wpwrak | but a blinking cursor (if there is a finger) means the threshold is too high |
| 05:48.18 | xiangfu | ok. I made a mistake. dnow. changed to 5. |
| 05:48.41 | xiangfu | hmm... still blinking when there is a finger. |
| 05:49.35 | wpwrak | with 5, it should detect the finger when it's ~1 cm away :) |
| 05:50.00 | wpwrak | did you put some plastic on top of the sensor ? if yes, how thick is it ? |
| 05:50.09 | xiangfu | no. nothing on PCB. |
| 05:51.01 | wpwrak | ah, you should add some ~0.5-1.5 mm of plastic |
| 05:51.33 | wpwrak | else, the thing will be far too sensitive |
| 05:51.38 | xiangfu | ok. |
| 05:51.47 | xiangfu | finding some plastic... |
| 06:13.30 | wpwrak | i think i found a fast calibration that works :) not it should be ready after just a few milliseconds |
| 06:13.37 | wpwrak | noW |
| 06:13.56 | xiangfu | I found a plastic. |
| 06:14.03 | xiangfu | it works fine at thresh = 250 |
| 06:14.23 | wpwrak | if the fast calibration didn't work, then anelok may turn on and off on its own for a while (until the regular calibration corrects the issue) |
| 06:14.26 | wpwrak | whee ! :) |
| 06:15.46 | xiangfu | better on 350. |
| 06:15.50 | wpwrak | in general, if the slider acts weird, let anelok rest for ~30 seconds and the problem should correct itself |
| 06:16.00 | xiangfu | ok. now I am ready to write some C code. :) |
| 06:16.12 | xiangfu | ok. |
| 06:16.38 | wpwrak | for the threshold, higher is better since you then only get samples where the finger is already firmly pressing against the plastic |
| 06:17.52 | wpwrak | if the sensor triggers when the finger it still away or only lightly pressed, then the finger will deform when completing the push, and this will look to the sensor like a change in position. so it's best to avoid that. |
| 06:21.40 | wpwrak | (code) great ! :) and welcome to the exclusive club of anelok users ! ;-) |
| 06:25.58 | wpwrak | ah, regarding the fat fs. best to call the directory of the file system driver fat/ or fatfs/. ff/ is a little too terse and generic, even for my taste :) |
| 06:27.02 | xiangfu | ok. got it. |
| 06:54.23 | xiangfu | now we have 4 full working board. |
| 06:55.55 | wpwrak | kewl :) until two hours ago it was 2 world-wide, one hours ago it was 2+1 = 3, now 2+4 = 6. if we keep this up, the planet will overflow with aneloks in a day :) |
| 06:56.12 | xiangfu | will upload more pics later. |
| 06:56.28 | xiangfu | :) |
| 06:56.28 | wpwrak | excellent ! |
| 06:56.45 | xiangfu | I think I can start the case work after Chinese New Year. |
| 06:56.53 | xiangfu | and making more boards. |
| 06:57.16 | xiangfu | I have bought 50 boards components. but I only have 10 PCB. |
| 06:59.11 | wpwrak | that's good. it seems that we'll need to change the power supply scheme anyway, then you can fix that directly in the new boards |
| 06:59.36 | xiangfu | Yes. |
