[13:54] <Zuph> Dan-K2VOL: What's up since last night?
[13:55] <priyesh> Dan-K2VOL: have done.. but most focus on converting lines from 5v to 3v3. that's not my issue
[13:58] <W0OTM> woot, iHAB test flight tomorrow
[13:58] <Zuph> priyesh: 4.7k pullup for CS, no resistor for MISO unless you're using ISP programming.
[13:58] <priyesh> Zuph: i am using ISP
[13:58] <Dan-K2VOL> zuph spent till 3 am troubleshooting why it wouldn't ballast, finally realized that I had to set every threshold altitude every time you reprogram. by that point there was no time left to test

[16:47] <Zuph> I'm trying to make a fool-proof power handover circuit for future long duration flights, so the flight computer can automatically switch from ground to flight power. It need to be very reliable, and I'm not sure what the *best* way to do it is.
[16:47] <NigeyS> nickolai, whats the link ?
[16:47] <NigeyS> Zuph, 2 hamsters instead of 1 ;)
[16:47] <nickolai> NigeyS: http://www.ukhas.org.uk/guides:inventek-ism300
[16:48] <eroomde> Zuph: auto change over on disconnect?
[16:48] <eroomde> or will the flight computer have prior warning?
[16:48] <NigeyS> tnx nickolai
[16:48] <nickolai> np
[16:48] <Zuph> eroomde: I'd like it to be able to do change on disconnect as well as change on command.
[16:50] <NigeyS> looks good nickolai, good job :)
[16:50] <Zuph> So, maybe a logic line + voltage from the ground umbillical going into an old style 74 series OR, driving a NC relay, with whatever circuitry necessary to make the voltage work out. Seems like a failure at any point would stick it in "flight power"
[16:50] <SamSilver> have you seen the new ublox 6 low power unit http://www.falcom.de/products/gps-modules/fsa03-lp/

[21:59] <Randomskk> there's libopenstm32 / libopencm3 which supports many peripherals but not as many, but is nicer
[21:59] <Randomskk> there's ChibiOS, which is an RTOS (real time operating system) that runs on the STM32, providing you with things like threads and mutexes and all sorts of good stuff, and its HAL (hardware abstraction layer) provides drivers for most of the STM32 functionality
