MSP430G2553: Sequential AD conversion

Part Number: MSP430G2553

Hello,

I have  a little project in interest. In that I would like to sample AIN5 and the chip temperature sequentially 16 times both for filtering. Is it possible? I mean sampling not consequtive channels; or it must be done in two step: sampling 16 times AIN5 and 16 times temperature.

Another question, the compiler gives error on ADC10AE1. Is it; because, they are not pins rather internal connections made with INCH_10 for example? So, ADC10AE registers can not be used sequencing channels?

Regards,

LAszlo

  • If you are going to digitally filter the ADC results you will get the best performance with uniform samples at sixteen times the output rate. Making rapid samples in  sequence doesn't do the trick since the input signal probably doesn't change much in that short time.

    ADC10AE1 is a register that does not exist on this particular device.
