G2553 ADC problem

Tanmay Gadekar

Hi,

I am using G2553 to read ADC values. I have configured the ADC for multichannel sampling for ports 1.0,1.3,1.4,1.5,1.6 and 1.7. I am using ports 1.1 and 1.2 for RXD and TXD. The problem I am facing is that I am able to read values from ports 1.7 to 1.3 correctly, but I am not able to read port 1.0. I have used ADC10DT for direct transfer of values to another register.

From what I have read in the user guide,the ADC samples from chl 1.7 to 1.0 during multiple conversions if I have configured the control register with INCH_7. Also for clarification, when I individually configure port 1.0 for single channel sampling I get proper values. So I can conclude there is no hardware problem.

Thanks.
