can you try this (works fine for e.g.1132): ADC10CTL0 = SREF_1 + ADC10SHT_1 + REF2_5V + REFON + ADC10ON; ADC10CTL1 = INCH_1; // A1 ADC10AE = 0x02; // P2.1 ADC option select
ADC10CTL0 |= ENC + ADC10SC; // Sampling and conversion start while (!(ADC10CTL1 & ADC10BUSY)); // ADC10BUSY? adc = ADC10MEM; which device do you use ? matthias -----Ursprüngliche Nachricht----- Von: mspgcc-users-ad...@lists.sourceforge.net [mailto:mspgcc-users-ad...@lists.sourceforge.net]im Auftrag von amol shrotri Gesendet: Mittwoch, 02.
