| 10:29:15 | JdGordon| | actually, does %mp return strings or numbers if it isnt used in a conditional? |

| 12:38:06 | TheSeven | battery current reported by ADC when unplugged: 13-14mA, battery current reported by ADC when plugged: 7-8mA, USB current when plugged: ~11mA |
| 12:38:20 | TheSeven | i know it isn't charging, so the plugged ADC value is probably spurious |
| 12:38:39 | TheSeven | AFAIK the charging regulator is a linear regulator |
| 12:38:47 | TheSeven | so I'd say the ADC is off by ~7mA |
| 12:38:56 | TheSeven | second measurement: |
| 12:39:23 | TheSeven | ADC unplugged: 35-36mA, ADC plugged: 7-8mA, USB plugged: 45mA. huh? explanations? |

| 12:45:10 | TheSeven | saves a whopping 2mA! |
| 12:47:10 | TheSeven | hm, no, that was apparently a fluke |
| 12:47:52 | Buschel | TheSeven: yes, LCD voltage reduction was submitted by myself −− it does not only reduce power consumption, it stopped the humming noise of the LCD :) |
| 12:48:27 | Buschel | (which is far more important for myself as I am really sensible to such noise) |
| 12:50:01 | Buschel | btw, the nano sucks more battery current for me since a while (~20mA, measured by the ADC). Not sure why this is, even using older rockbox-builds does not reduce it back to the ~18mA I've measured before... |
| 12:50:26 | Buschel | all measured when playing back the same file of course |
| 12:50:48 | liar | TheSeven: i don't have the opened-up ipod anymore... |
| 12:51:52 | Buschel | TheSeven/liar: another option to save more than 2mA via white-background is to switch LCD off via using liar's patch ;) |
| 12:52:00 | TheSeven | funny: locking the hold switch (which I would have though powers off the clickwheel) *increases* current by 0.5mA! |
| 12:52:18 | TheSeven | Buschel: that's what I will try now |
| 12:52:21 | Buschel | TheSeven: btw, the difference between your and my measurements could be caused by this background-effect. I am using a black one ;) |
| 12:52:40 | TheSeven | this wasn't reproducibly |
| 12:53:09 | bertrik | TheSeven, maybe some pull-up or pull-down resistor on the hold switch drawing current? |
| 12:53:26 | Buschel | what wasn't reproducible? the background- or the hold-switch-effect? |
| 12:53:35 | TheSeven | bartrik: that would be way too much, considering that this would also happen if the device is powered off |
| 12:53:40 | TheSeven | the background one |
| 12:54:34 | Buschel | a pitty, this could have solved easily... I have some white-bg WPS as well |
| 12:55:08 | bertrik | I don't see why that would happen when powered off |
| 12:55:18 | ranmachan | I have an experimental patch for AMS, that uses the MMU to write-protect code, and moves interrupt vectors to the alternate high address to trap null-pointer dereferences. I was thinking this could be nice for debug builds |
| 12:57:58 | TheSeven | Buschel, liar: do I understand correctly that you aren't even shutting off power to the lcd in that patch? |
| 12:58:29 | TheSeven | bertrik: the hold switch can be used to wake the device |
| 13:00 |
| 13:01:24 | TheSeven | also, disabling the lcd controller clock gate could further reduce power consumption |
| 13:05:23 | liar | iirc currently i just send it into sleep mode. do we know how to shut the power to the lcd off? |
| 13:07:41 | Buschel | we know how to switch off the power supply, and it seems like TheSeven knows how to switch off the clock gating |
| 13:09:17 | TheSeven | shutting off the power supply increases current by ~20mA. probably still some voltage on data lines to the lcd or something. |

| 15:09:29 | [Saint] | Buschel: I'm getting another Nano1G tomorrow or the next day, so bug me then if you've not had a tester already. |
| 15:09:40 | Buschel | i will :) |
| 15:10:13 | keenerd | TheSeven: And I was pretty sure USB ports can't detect to that resolution. If at all. Not possible under linux. WIndows might to 10mA, but that might just be the device reported max current. |
| 15:10:13 | * | [Saint] can't wait, he's been stuck with Nano2G too long. |
| 15:13:28 | keenerd | TheSeven: What ammeter? All mine have too high impedance on anything but the 10A setting. I have an (easily slammed) 20mA dial meter that works and an 0.1 ohm meter I made myself. |
| 15:19:03 | soap | does the nano 1G now have a way to report the current consumption through the debug menu or are you needing benches, Buschel? |
| 15:19:17 | soap | I haven't fired mine up in months. |
| 15:20:07 | amiconn | Buschel: I think this test also requires a dock / line out adapter of some sort |
| 15:20:12 | Buschel | hmm, I don't think there is any debug screen showing the consumption. but it would be fine to check whether the patch does what is meant to do |
| 15:20:34 | soap | and, yea, what amiconn said. |
| 15:20:48 | amiconn | I don't have such an adapter, otherwise I could do that test (but later, as I don't have my Color with me) |
| 15:23:54 | TheSeven | keenerd: no idea what the impedance of that one in the 40mA (10µA resolution) range is, but it's low enough |
| 15:24:05 | TheSeven | the ipod will tolerate like 4.5V, and i'm feeding it with clean 5V |

| 15:38:09 | [Saint] | been a while since I did a bench on Nano2G |
| 15:38:19 | TheSeven | I'm sure there are tracks that need even more power, but it's still way above what apple manages to reach :) |
| 15:38:43 | [Saint] | didn't they advertise 18 for the 2g? |
| 15:38:49 | [Saint] | 18hours |

| 15:51:06 | [Saint] | TheSeven: If it is, I would say it should be changed. |

| 20:05:36 | TheSeven | forcing it to 100/200MHz increased the average current by 2/4mA |
| 20:06:00 | Buschel | TheSeven: ok, how much can we save when lowering the lower limit to 24 MHz? |
| 20:06:11 | Buschel | so, 24 MHz vs. 48 MHz? |
| 20:06:26 | TheSeven | we'll get trouble with the APB if we do that, because the tick timer etc. is based on that |
| 20:06:48 | TheSeven | and i don't think it's worth it, as most codec are occasionally boosting at 48mhz |
| 20:07:29 | Buschel | really? I didn't test mp3 at 48 MHz, but mI would expect it to run w/o boost |
| 20:07:44 | TheSeven | it doesn't |
| 20:07:55 | TheSeven | it needs ~50-60Mhz |
| 20:08:11 | Buschel | you got the numbers from test_codec? |
| 20:08:14 | TheSeven | on the other hand, embios is always running at 192mhz and needs less current than rockbox, probably because it's in irqwait mode most of the time |
| 20:08:28 | TheSeven | no, from the buffering debug screen and boosting experiments (forcing to 48mhz) |
| 20:08:39 | Buschel | ok |
| 20:08:48 | TheSeven | there were a few tracks that played without glitches, but the pcmbuf never held more than 50KB |
| 20:09:06 | TheSeven | and the UI was very, very sluggish |
| 20:09:56 | Buschel | the lcd updates might also have taken some cpu as well... |
| 20:09:57 | TheSeven | that's another reason I wouldn't want to use 24Mhz: the UI will be laggy |
| 20:10:10 | TheSeven | even if it's idle |
| 20:12:20 | Buschel | ok. another question: is there any reason to use a 48/96/192 instead of 50/100/200 scheme? |

| 20:14:36 | TheSeven | Buschel: because apple is doing it that way |
| 20:14:56 | TheSeven | and because it actually divides quite nicely |
| 20:15:06 | bertrik | Possibly also to get good sampling rate accuract |
| 20:15:17 | TheSeven | that's independent of the cpu clocking |
| 20:15:41 | TheSeven | it isn't even 192MHz, it's 191692800Hz |
| 20:16:13 | Buschel | I will try PLL0PMS = 0x006501 in a minute, that will use 200.9 MHz instead of 192 |
| 20:17:34 | Buschel | if I am not mistaken... let's see |

| 22:18:45 | mrkiko | Hi all!!! |
| 22:19:15 | mrkiko | Finally I'm about to run rockbox again! And now I'm here for a simple question (I know I can read the buyer's guide, but I would like a more personal perspective) |
| 22:19:43 | mrkiko | I would need a device which: - can run rockbox; - has a very long battery; - offers lots of space. Don't mind if it's flash or disk-based. |
| 22:19:57 | mrkiko | What do you recommend? |
| 22:20:10 | TheSeven | what is "lots of space"? more than 32GB? |
| 22:20:19 | n1s | define "long battery" too please |
| 22:20:47 | mrkiko | even 32 GB can sufficie. Long battery? Long as possible - no particular requirements ... |
| 22:20:57 | mrkiko | I need to use it with speech aniway |
| 22:21:01 | mrkiko | *anyway* |
| 22:21:14 | mrkiko | I'm blind so the display size is not important |
| 22:22:35 | mrkiko | And definitely - it would be better for the device to be very resistant to any kind of hostile environment :) |

| 22:22:40 | n1s | iaudio m5l and x5l models have very long battery times but I think they are not available in sizes over 30GB |
| 22:23:09 | mrkiko | ok... I'm taking down the names to analyse them later |
| 22:23:49 | n1s | one of the sansas with µSD slot with a 32GB card could work too |

| 22:27:06 | mrkiko | ... ok! I'm looking the two specified here, trying to understand differences between m5l and x5l |
| 22:27:37 | n1s | the main difference is that the x5 has a color display |
| 22:28:11 | pixelma | and usually a radio |
| 22:28:18 | mrkiko | ah ok |
| 22:28:23 | mrkiko | the m5 is out of production right? |

| 22:31:13 | gevaerts | Zagor or Bagder |
| 22:31:32 | TheSeven | ah |
| 22:31:57 | gammy | mrkiko: I have an iRiver iHP 120 and an iAudio x5l here and I've been fiddling with both today. |
| 22:32:58 | gammy | mrkiko: I uh, also purchased a 2GB Sansa Fuze today on ebay, the plan being to test it (if it isn't a revision 4?) and if it's nice puchase a 16Gb microSD card for it. |
| 22:34:54 | gammy | mrkiko: The iRiver is the only one I have extensive experience using. It worked for almost ten years, and I modded it for a 32Gb CF card as well. Unfortunately I blew up the audio output stage some time ago, and now I'm experimenting with the iAudio |
| 22:34:59 | gammy | (which a friend gave me) which has a faulty "secondary" battery (the iAudio annoyingly having two) |
| 22:35:14 | gammy | Phew. A lot of typing and probably off-topic, I thought this was #rockbox-community. |
| 22:37:17 | pixelma | gammy: only the "L" models have two and unfortunately the Iaudio batteries don't seem to be the best ones (saw it with two "normal" X5s in the family and my M5L also lost quite a lot but still has quite nice runtime overall |
| 22:37:32 | pixelma | ) |
| 22:38:57 | gammy | pixelma: Ah I see. Yeah the one I have was given to me by a friend as it wouldn't start up at all. Disconnected the large battery and it started up. I'd like to know if the iRiver battery is compatible. Then again it could be the charger that's |
| 22:39:01 | gammy | faulty. |

| 22:40:28 | gammy | I also tried my iRiver CF mod with the iAudio. It can boot up and put me in a menu. but then panics when I try to list files. I assume it's due to the timings on the CF card, but it's a shame since it works so well in the iRiver. |
