MSP430F5131: ADC10 example will not build out of box. Missing register definitions in header files.

Part Number: MSP430F5131
Other Parts Discussed in Thread: MSP430F5132

Hi Experts!

I tried to build any ADC example code for the MSP430F5131. The code example I want to use is MSP430F51x2_ADC10_07.c

However, this is a problem with all ADC10 example codes. The issue is ADC10 registers are not defined in the #include <msp430> header.

After I add #include <msp430F5132.h> (which defines all the registers ADC10CTL0, ADC10SHT_2,...), I still get a similar but different error.

Now, ADC10CTLx registers are undefined.

(Side note: I did not #include F5131.h files because these files do not define registers ADC10CTL0, ADC10SHT_2,...)

Is there another header file I must include? Wanted to raise awareness of this issue that all MSP430F5131 ADC examples will not build out of box.

You should only need to include msp430.h and it will select the appropriate header file for the specific device based on the compiler settings. Including a file for another part will only cause trouble.

I checked the f5131.h file I have (from the GCC distribution) and the ADC10 definitions are not included. They should be so this is an error and will have to be corrected. I noticed that the addresses for the ADC10 registers are also missing from the linker scripts. Hopefully someone will tell the compiler guys about this problem.

If you need to compile something right away and can't wait for the next compiler release, you can edit up the header and linker scripts. Tedious at best.

Just noticed, the 5131 does not have an ADC! My mistake

The MSP430F51x2, MSP430F51x1 Mixed-Signal Microcontrollers datasheet (Rev. R) shows that the MSP430F5131 doesn't contain a ADC10 module:

Therefore, it looks correct that the MSP430F5131 include file doesn't contain the ADC10 register definitions.

Thank you Chester! My mistake on this, and thank you for the quick responses.

I would like to point out the TI Resource Explorer puts these example files under the MSP430F5131 folder. In my opinion we may want to remove these.

TThank you again!
