Msp430 Example Code
Msp430 Example Code Assembly
Hello Joshua,I copied your code excerpt and was able to get it working from the start with CCS V6.1 and TI Compiler V5.2.2. I tested it by wiring the MSP-EXP432P401R 3V3 pin to P5.4, in which case LED1 would turn on. Upon disconnection the LED would turn off. So your firmware is fine, the problem lies somewhere in the hardware. Make sure that the voltage you are supplying to P5.4 is greater than half of AVcc (1.65 V) and you could even try a continuity test between the P5.4 header and pin on the MSP432P401R device to make sure that the connection is sound. You could also make sure that the LED header is properly connected, but seeing as how you aren't able to enter the ADC ISR at all I doubt that this is the issue.Guns up,Ryan. I confirmed that if I check ADC14MEM0 before the sleep code LED0 is controlled properly.What's odd is that it only works once and if I pause the debugger it is caught in the defaultISR routine of the msp432startupccs.I'm running the latest CCS 6.1.2 with all updates applied and working with the sample code so I'm at a loss as to why it seems the USR is not being handled properly.Update.
After doing a little more searching I ran across this thread, which gave me the clus that the startup file didn't get copied over when the project was created. I thought that would be the answer but unfortunately after making that change I am now not able to connect to the board. I don't think it's directly related to this but until I can fix this new error I am no longer able to debug code. All content and materials on this site are provided 'as is'.
