wpwraki'd call this "project evolution" :)00:17
rjeffrieswpwrak that link is for YOU!00:31
rjeffrieswpwrak which MCU are you using for your current project?00:40
wpwrakright now, an avr (attiny87 or 16700:49
wpwrakbut depending on the occasion, i also use silabs c8051f3xx, microchip pic, and maybe soon the little arms from nxp00:51
rjeffriesNXP 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
wpwrakthat was an unusual way to mistype "inactive" ;-)00:56
wpwrakso 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
wpwrakbesides, what really matters usually isn't super-low standby current but how often you have to wake up while in standby00:58
rjeffrieswpwrak 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
wpwrakyeah, they're heavily marketed towards low power01:06
