MSP430 - Serial configurable PC 4-NTC 4-fan controller

[Willaim]

Been working on a project PWM controlled 4 NTC temp sensors 4 PWM controlled fans for my pc case
got most of the code for the PWM done and the temp sensors still a ways off yet ill post some code in the next week or so
it will eventually interface to a sparkfun LCD based on the amtel 328p with a button pad and rotary encoder
will be configurable through the lcd which will also display temps directly from the msp430g2553 as well as serial commands from the pc if i get my way..


no RPM measurement as i'm running low on pins

the NTC sensors aren't the most precise but a look up table helped with the non- linear response
I used the vcc as the ref on the voltage divider will have to see how accurate it is over a few days to a week

here is the code for the PWM if anyone is interested i'll upload more code such as the NTC sensor and the final project when its finally done still waiting on some Logic level fets
