Hi,
I'm not having a lot of luck with Google finding the TI specifications for the temperature range of either this board, EXP430F5529LP, the MSP-EXP430G2, or other MSP430 based, LaunchPad boards. Trying to use a search term with "temperature" brings a lot of hits about how to read the internal temperature thermistor but nothing showing the hardware temperature range (been there, done this: http://hiwaay.net/~bzwilson/temp_recorder/.)
My application is automotive but with attention to packaging, I can probably handle 85C without 'going nuts.' Key requirements:
- low power - it is a battery monitor and we don't need any additional, parasitic loads
I've been looking at the Arduino but it has pretty sad overhead. I've tested some of the Arduino low-power modes but am not impressed. Worse, I get the impression they don't really have a broad temperature range but this has not been tested, yet. There is an Arduino hack that uses an external circuit to disconnect the Arduino to reduce the overhead but YECK!
My application needs to monitor the battery voltage using the slowest, lowest power mode possible. When a change occurs, wake-up to record and track the changes. Operating at the lowest possible voltage also solves another technical issue so we can track individual cell performance in the battery.
I was impressed with the EZ430-F2013 as the daughter board easily handled 100C but the USB stick did not survive the 'live steam' test. But I'd rather not have to deal with the inventory issue of a USB stick.
Any help?
Thanks,
Bob Wilson
ps. My last MSP430 project was a Prius thermistor hack to shorten warm-up:
