| 00:18.38 | MonMotha | indeed |
| 00:18.45 | MonMotha | then there's Labview, which is useful for nothing :) |

| 00:21.10 | pingbat | haha, the labview licence was too expensive to use on students |
| 00:25.06 | MonMotha | they gave the place I went a major discount |
| 00:25.16 | MonMotha | we all had it on our laptops |
| 00:25.29 | MonMotha | not willingly, mind you, but a few classes required it |
| 00:25.37 | MonMotha | I was ecstatic when I discovered the MATLAB block |
| 00:25.45 | MonMotha | the assignment used labview, as required :) |
| 00:30.20 | pingbat | haha |
| 00:31.47 | davidc__ | MonMotha: I did similar stuff |
| 00:31.59 | davidc__ | we had to write some stupid game in Delphi, as that was the "learn OO language" at my school |
| 00:32.12 | davidc__ | MonMotha: I tried to use OpenGL through delphi, but got shut down |
| 00:32.39 | davidc__ | MonMotha: I just made sure they never saw my liberal usage of the ASM keyword until I handed it in |
| 00:32.46 | davidc__ | and by that point it was too late for them to add requirements :D |
| 00:38.03 | roxfan | hmm, nxp announced lpc17x9 models... up to 120MHz |
| 00:40.42 | pingbat | do you have link? |
| 00:41.47 | roxfan | http://ics.nxp.com/lpcxpresso/~LPC1769/#LPC1769 |
| 00:42.41 | roxfan | looks like they're otherwise equivalent to 17x8 ones |
| 00:44.43 | MonMotha | davidc__: heh, nice |
| 00:46.39 | Mirell | Sigh. |
| 00:47.00 | pingbat | just as the 100MHz luminary devices are coming out |
| 00:47.25 | MonMotha | lpc17x9 is what core? |
| 00:47.29 | pingbat | M3 |
| 00:47.35 | pingbat | cortex-M3 |
| 00:47.39 | MonMotha | M3 at 120MHz should be fairly speedy |
| 00:49.34 | roxfan | yeah nxp is moving pretty fast with cortex m parts |
| 00:50.29 | roxfan | M0 silicon was released unnaturally quickly after announcement for an arm part |
| 00:50.53 | pingbat | on the ARM docs they claim to get 1.25 DMIPS/MHz for M3 |
| 00:51.31 | MonMotha | I still want to do an A8 or A9 based ultraportable |
| 00:51.45 | pingbat | how does that work? |
| 00:51.54 | MonMotha | basically figure a small netbook but with an ARM in it |
| 00:52.10 | roxfan | http://www.dspdesignline.com/news/217300482 |
| 00:52.27 | MonMotha | with solid state storage (big SDHC or CF card), you can easily make the darned backlight on the LCD the biggest power draw on the system by a few orders of magnitude |
| 00:52.58 | roxfan | use e-ink then :) |
| 00:52.58 | MonMotha | I know Freescale just released a reference design for a device kinda like that based on their i.MX, and there's also the Always Innovating Touchbook using OMAP |
| 00:53.18 | MonMotha | e-ink is an interesting idea since the biggest use is probably web browsing |
| 00:53.39 | roxfan | then don't... eink is terrible for scrolling |
| 00:53.51 | MonMotha | yes, you'd have to jump by page basically |

| 00:57.00 | ercani | I have a question |
| 00:57.18 | ercani | there are some mobiles such as nokia |
| 00:57.27 | ercani | os is symbian |
| 00:57.37 | ercani | is it possible to run on linux |
| 00:57.58 | roxfan | run what on linux? o.o |
| 00:58.02 | ercani | by installing kernel into sd card |
| 00:58.26 | roxfan | do you maybe mean run linux on the phone? |
| 00:58.31 | ercani | yes |
| 00:58.50 | roxfan | depends on the phone... what cpu, ram size etc |
| 00:58.54 | ercani | arm9 200 mhz |
| 00:59.09 | ercani | 16 mb ram |
| 00:59.24 | roxfan | that's doable |
| 01:00.33 | roxfan | but of course it's not very likely that there's a kernel available for your specific model |
| 01:09.03 | pingbat | has anyone tried the pandora? |
| 01:10.27 | pingbat | well, i don't think they're done yet but has anyone looked into it? |
| 01:14.23 | SpeedEvil | ercani: and hten there is the one that runs it natively |
| 01:16.01 | ercani | where ? |
| 01:16.08 | ercani | hten ? |
| 01:17.51 | SpeedEvil | n900 |
| 01:53.48 | ercani | one more question |
| 01:54.06 | ercani | can I apply dualboot on a mobile ? |
| 01:54.11 | ercani | say wince and linux |
| 01:54.39 | ercani | both installed into rom |
| 01:55.26 | SpeedEvil | Yes. |
| 01:55.39 | SpeedEvil | But that's a 'yes - if you port it yourself' |
| 01:55.49 | SpeedEvil | you will almost never be able to change os |
| 01:56.07 | SpeedEvil | on a phone without at best weeks of development work and have it work even minimally. |
| 01:56.33 | SpeedEvil | Unless it's supported by the maker or some other group. |
| 01:57.03 | ercani | if I get the phone with empty flash |
| 01:57.06 | ercani | ? |
| 01:58.19 | ercani | I have red some about redboot bootlader for pxa 310 |
| 02:01.52 | SpeedEvil | Booting is not the problem |
| 02:02.21 | SpeedEvil | you have to get all the peripherals supported and the application software working with those peripherals to make a whole phone stack. |
| 02:02.43 | ercani | say I have dll's for wince |
| 02:02.44 | SpeedEvil | If you don't have those - without docs - it may be months or years of work to bring a new OS up. |
| 02:02.55 | SpeedEvil | assuming you have the skills as an embedded programmer. |
| 02:03.23 | ercani | if I have datasheet |
| 02:03.24 | SpeedEvil | If wince is supported on the platform, in principle it's a lot easier, but you still have the applicaiton layer to go |
| 02:03.37 | ercani | yes it is supported |
| 02:03.46 | SpeedEvil | datasheet for what? |
| 02:03.52 | ercani | mainboard |
| 02:04.12 | SpeedEvil | what phone are you talking about? |
| 02:04.19 | ercani | pxa 310 based |
| 02:04.48 | SpeedEvil | never done any wince work. |
| 02:05.14 | ercani | is it hard to install linux if flash is empty ? |
| 02:06.00 | ercani | sd card can be used for it ? |
| 02:07.11 | SpeedEvil | It totally depends. |
| 02:07.27 | SpeedEvil | Yes, you can install lnux from a SD card - if the bootloader suports it |
| 02:07.40 | SpeedEvil | and the distribution you install understands the hardware |
| 02:08.21 | ercani | ok |
| 02:08.25 | ercani | tnx |

| 20:37.44 | alex4nder | Hi. |
| 20:39.01 | Redhatter | Im |
| 20:39.24 | Redhatter | I'm feeling complex today :-) |
| 20:40.16 | Mirell | Ah. |
| 20:40.18 | alex4nder | has anyone in here implemented a USB device stack from scratch? |
| 20:40.30 | Mirell | Can't say that I have. |
| 20:42.40 | alex4nder | hmm. |
| 20:43.02 | alex4nder | I'm starting in on one.. and the USB spec looks way simpler than any of the reference implementations I've seen |
| 20:43.16 | alex4nder | I can't tell if I'm just oversimplifying, or if the implementations are just ridiculously verbose. |
| 20:43.29 | SpeedEvil | alex4nder: have you seen the tinyusb stuff |
| 20:43.59 | alex4nder | SpeedEvil: I haven't |
| 20:44.03 | SpeedEvil | usbtiny I mean |
| 20:44.06 | SpeedEvil | google usbtiny |
| 20:44.25 | alex4nder | ah, sick. |
| 20:45.22 | alex4nder | that's a great hack. |
| 20:48.00 | alex4nder | that software implementation is an order of magnitude smaller than the reference code for the at91sam7's hardware interface. |
| 20:51.10 | SpeedEvil | that is of course 1.5mbps moed only |
| 20:51.14 | alex4nder | sure |
| 20:51.35 | alex4nder | but most of the complexity in USB seems like it's managing state and setting up the descriptors correctly. |
| 20:51.51 | alex4nder | (especially if hardware is handling all of the physical bus interaction) |
| 20:52.26 | SpeedEvil | yeah |
| 20:53.41 | alex4nder | my goal is to get this board to bring up a control pipe, and at least register itself on the USB, by tonight. |
| 21:28.47 | SpeedEvil | Good luck! |

| 21:49.27 | alex4nder | this datasheet sucks, in that it doesn't tell you what the hardware actually implements. |
| 21:49.49 | alex4nder | it's not obvious to me, that the UDP handles NAKing, PIDs, and all of the other groddy USB stuff for you, automatically. |
| 21:52.03 | SpeedEvil | Check if you're not missing a 'programming the USB bit' document |
| 21:53.40 | alex4nder | Yah,. I've found the app notes for programming USB, which is tied to their reference implementation. |
| 21:54.52 | alex4nder | they go through and document the C API they ship. |
