// MSP430G2x33/G2x53 Demo - ADC10, Sample A7, 1.5V, TA1 Trig, Ultra-Low Pwr // // Description: A7 is sampled 1024/second (32xACLK)with reference to 1.5V. All // activity is interrupt driven with proper usage of MSP430 low-power modes, // ADC10 and Vref demonstrated. Timer_A with both TA1/TA0 used in upmode to // drive ADC10 conversion (continuous mode can also be used). Inside // of TA0_ISR software will enable ADC10 and internal reference and // allow > 30us delay for Vref to stabilize prior to sample start. Sample // start is automatically triggered by TA1 every 32 ACLK cycles. ADC10_ISR // will disable ADC10 and Vref and compare ADC10 conversion code. Internal // oscillator times sample (16x) and conversion (13x). If A7 > 0.2Vcc, // P1.0 is set, else reset. Normal Mode is LPM3. // //* An external watch crystal on XIN XOUT is required for ACLK *//
