msp430

My original plan was to use a MSP430 based launchpad (cheap!) instead of an Arduino for the sensor part. I had major troubles getting any data to go trough so decided to first try with identical platforms and libraries. That worked so at least I knew that my NRF modules where ok.

Getting this when trying to open the serial port to your MSP430 on a launchpad ?

FATAL: cannot open /dev/ttyACM0: Input/output error

The reason seems to be that a buffer on the serial converter gets full and the chip gets upset and fails.
But you can easily workaround it. Disconnect the serial pins from the "emulator" (why do they call it an emulator in first place, I don't get it, it does not emulate anything) part on the board by removing the jumpers.

I've been planning, for a long time now, to create a monitoring system to our summer cottage. Features would include monitoring of temperature of air and lake water (the cottage is by a small lake) and why not air moisture and barometric presure just for fun.

Also monitoring the sauna temperature in some inteligent way, for example for informing to add more wood and "Sauna is ready!" signal.
