Partner and I are very stuck on this one. It was working earlier, now it's not.

The code has been uploaded to GitHub: github.com/SwimDude0614/CID.git

Our problem line is 119 of CID.c.

Overview:

1) Enter main

2) Call sysInit()

a) Call rdTmrInit()

b) Call adcInit()

c) Die on the last line of adcInit()

Hi,

Your expression INT_ADC0SS1+SEQUENCE evaluates to 32 instead of 31 as needed - the second term is defined in globals.h as 1...

Ah, forgot to clean that up. We tried deleting the "+ SEQUENCE" and manually putting in INT_ADC0SS1 but it didn't help.

HI,

In this case it is time as good as any to download and read the application note AN01286.pdf - "Diagnosing Software Faults in Stellaris Microcontrollers" - it is a must to read to learn how to play with the powerful fault engine implemented inside the chip.
