Hi, I am using MSP430 launchpad with G2553 controller. When I am using sleep(5000), and varying the voltage on the controller from 3v to 4v the timing is varying based on the voltage, but the timing in not changing when I am using delay(5000) when I am varying voltage. Any help will be appreciated. Regards,

I am using micro SD card to log reading from four force sensors connected to the microcontroller (MSP430G2553). Controller logs reading to the SD card every 15 minutes and goes to sleep. I am using 1000 mAh battery, which is lasting over a week. Is it possible to reduce the power consumption as to make it last over a month. (#) Even if the microcontroller is sleeping for 15 minute, SD card is continuously consuming power. (#) It takes couple of mA to write. Help with any suggestion to reduce to power consumption drastically. Schematic and code (attached). Code_D
