reading about fixed-point arithmetic….real world data is not sweet integrals…need to find out the most efficient way to multiply fractionals on the MSP430 using the on-chip hardware multiplier..got tons of nice reading material online

another meeting today…read about the onchip hardware multiplier on msp430 and its operation…got some epilepsy data to look at today

had a looong meeting with the supervisor(s) today to discuss the next stage of the project…the upcoming work is pretty interesting..time for some signal processing stuff perhaps

gotcha!!! bloody bug caught
a basic crude fat16 implementation has been completed today -
admin
duhhhh…..im very close to implementation of fat16…..stuck at a weird bug…code working on alternative resets :S :S
-
admin
so fat16 it is that i need to implement

woaaahh!! just realised whatever i was writing on the SD card, wasn’t actually written…and the errorcheck reported successful communication … i was testing against a zero condition, opening the sd disk in a hex editor showed that all unused sectors were zero and hence the true test…damn!

done reading about the FAT16 file system…seems like a daunting task to implement on the lil MCU…but ppl have done it…will hv to talk to the supervisor first

testing out another code to initialize the sd card – something on which it can be easier to build a file system (maybe :S)
