Basestation 2010
From Glacsweb Wiki
Base station 2010/11 design
Gumsense2: msp430 co-processor PCB
- Job Structure 2010 - new job structure
- What Vcc? Overo is 1.8V - level converters used
- MSP430F5 series for a good RTC and I/O - perhaps same as probe msp for code sharing?
- switchable power outs which can be controlled by the msp on it's own, or by the gumstix via the msp
- msp adc inputs available on headers
- should have connections for at least 2 sht15 sensors? (one on pcb, one remote)
- should have i2c available (what voltage?) for connecting external sensors
- should be able to schedule sensor readings (some readings are instantaneous, others take a while eg gps)
- human readable script for config/settings/jobs - via serial
base station power requirements table for all modules
base station timers - how wake-ups and schedule/sampling will be done
Patches to reflect on circuit diagram
- pull up for vbat should goto vcc not 3.3v
- psu switch to Switch mode
- re add jtag?
- 100k pull up for battV fet
- Remove all 0402 packages
