| 23:13.43 | MonMotha | ds2: I've seen it done, though I've not done it myself |
| 23:13.59 | MonMotha | biggest issue is that it puts yet another device on the board that has to be programmed (either ahead of time or ISP) |
| 23:14.04 | ds2 | trying to find if there are any gotchas before attempting it myself ;) |
| 23:14.21 | MonMotha | also of course you have to write the firmware, but it's not usually that complicated for such an application |
| 23:14.41 | ds2 | true but it seems a low end uC is almost cheaper then a proper GPIO expander and more stuff can be toss in there |
| 23:15.09 | MonMotha | sometimes yes |

| 23:15.24 | ds2 | sometimes? when it is not? |
| 23:15.45 | MonMotha | just gotta make sure that if price is your reason for doing it that additional production cost won't flip it back the other way |
| 23:16.04 | ds2 | ah big picture issues |
| 23:16.25 | MonMotha | yup |
| 23:16.35 | MonMotha | it's also another target for bugs |
| 23:16.41 | MonMotha | but at least you can fix them :) |
| 23:16.50 | MonMotha | I've ended up with buggy silicon before. No way to fix those bugs. |
| 23:16.51 | ds2 | what I would like to find out is if I can get power gains by putting the main processor to sleep and letting the tiny uC do some of the grunt work |
| 23:17.08 | MonMotha | I've heard that technique |
| 23:17.14 | MonMotha | especially popular for power management tasks |
| 23:18.13 | roxfan | sony reader uses this approach |
| 23:18.51 | roxfan | they have an 8-bit low-power "sub" cpu to handle power and keyboard |
| 23:18.53 | MonMotha | I designed something (never made) that used an atmega48 for power management, the rtc, and some additional GPIO stuff |
| 23:19.34 | MonMotha | well, atmega48p (the "picopower" version, which is competitive with MSP430 in terms of power consumption) |
| 23:19.36 | roxfan | it talks to the main cpu over serial... they have a small command/response protocol |
| 23:19.41 | ds2 | IF the TI marketing literature for the MSP430 is not complete hot air, the 430 SEEMS like a nice chip for this... TSSOP14 and I get spare GPIO's as part of it |
| 23:20.13 | MonMotha | that's a valid application of an MSP430 |
| 23:20.21 | MonMotha | TI has an app note on using one as a "smart" RTC |
| 23:25.17 | roxfan | the one sony used was renesas H8/300L... i don't think it has many gpios but i guess they didn't need much |
