| wpwrak | i'd call this "project evolution" :) | 00:17 |
|---|---|---|
| rjeffries | wpwrak that link is for YOU! | 00:31 |
| rjeffries | wpwrak which MCU are you using for your current project? | 00:40 |
| wpwrak | right now, an avr (attiny87 or 167 | 00:49 |
| wpwrak | but depending on the occasion, i also use silabs c8051f3xx, microchip pic, and maybe soon the little arms from nxp | 00:51 |
| rjeffries | NXP does have a clever ARM M0 dev board. Got one free at a show. I want to get my hands on an ARM M0+ (VERY! low power in ac in ntive and sleep-y states) coming in next 30 days supposedly. | 00:54 |
| wpwrak | that was an unusual way to mistype "inactive" ;-) | 00:56 |
| wpwrak | so far, i didn't need any of the ultra low-power stuff. usually, a few uA in standby are quite bearable. even a CR2032 lasts for years with that :) | 00:57 |
| wpwrak | besides, what really matters usually isn't super-low standby current but how often you have to wake up while in standby | 00:58 |
| rjeffries | wpwrak agree, it is all about duty cycle. the radio is typically the power hog in a wireless sensor node, but the total power budget is worth minimizing. Ti430 is another decent option. | 01:04 |
| wpwrak | yeah, they're heavily marketed towards low power | 01:06 |
| LunaVorax | good evening | 20:15 |
