This is a minimal program that is executed directly from the reset vector and replaces the normal startup code. Compile with something like: msp430-gcc -Os -mmcu=msp430... -nostartfiles-o minimal...

Hi, when I set a break point in the adc12_ISR fro repeated single channel memory I get Following values for ADC12MEM0 Name : ADC12MEM0 Default:0x000720 Hex:0x000720 Decimal:1824 Octal:03440...

The code looks correct. It's possible that the adcResult array is not correctly defined, or read.

I don't think that problem is with the array.For example uint16_t val=(ADC12MEM0 & 0x0fff); does not work either. I tried MSP430F552x Demo - ADC12, Repeated Single Channel Conversions demo code it...

I have no specific links to libraries you couldn't find yourself. The stuff I found in a superficial search was mostly C++, Java or scripting (Matlab, R). This would be hard to swallow for a MSP430 ......

When is Timer_Init() called? I'd guess the code never updates TA1CCR1 again.

With the while loop, all you are doing is to wait in the loop as long as TxIFG is '0'. ie you are waiting until the TxIFG is set, before you wake-up the device and transmit the data. Without the while...

As shown in figure 1-1, the F5172 has a CPUXv2. (It adds not only 20-bit addresses, but also several useful instructions.)

Configure some timer for one second or so; execute the following code in the timer handler: counter++; if (counter >= 60 * 30) { counter = 0; // 30 minutes have elapsed }

The variable definition in the while loop hides the global variable. Anyway, the CCR1 register is updated only when the line "TA1CCR1 = Duty; " is executed.
