Hello Forum, I've been trying but without success to kickstart the ADC10 on a MSP430F1222. I can't seem to get ADC10 to work. I simply want to measure temperature and Vcc/2 using on-board peripherals. No external analog signals. I want to use the Internal reference too. I seem to be communicating with my FET okay. But setting break-points and 'watching' ADC10 registers shows that what

Hi, Is there both the modules ADC10 and ADC12 in msp430f248 ? And if there esxist; as it is written in the manual there are no pins for ADC10 but there are pins for ADC12 on msp430f248 and also in the header files used by CCE 3.1, msp430x24x.h, there is no definition for ADC10 module so; how can the ADC10 module be used? ------------------------------------

Hello, I have a question about the DTC in ADC10. I am trying to sample several channels sequentially. The ADC10 on the MSP430F2274 has a Data Transfer Controller, basically a DMA from what I understand. The code I see as example from TI sets most up, and I've made some modifications as follows: int delay; ADC10CTL1 = INCH_4 + CONSEQ_1; // A4/A3/A2/A1/A0, single sequence ADC10CTL0 ...

I've been using the ADC12 on the f149 quite happily for months now. However, I've just started working with the ADC10 on the f1232 and this is quite different. I'm using 3 analogue inputs A0, A1 & A5. I'm planning to use a sequence of channel conversion but am unsure exactly how much result memory I'll need. To define the sequence you load the ADC10CTL1 register with the starting chan

Hi, This ADC10 and its timing confuses me abit, the problem is as follows: i'm adding up the value from ADC10MEM in a variable (comparator), signaling when it reaches a threshold (Vtr), and i would expect the time it takes for Vtr to be reached to vary depending on frequency of the input signal, but it doesn't seem to do that. I wonder if anyone can explain to me a few things: *what

Hi, some newbie questions... I want to use the ADC10 on an EMG-signal sampled at 1kHz, but find it abit confusing which register settings need to be done regarding selecting analog input. I want to use P2.0 (A0) as analog input channel, is it correct to set the INCH0 in ADC10CTL1, and ADC10AE0 in ADC10AE and in addition set P2SEL |= 0x01 and P2DIR &= ~0x01 (details, details...)?

Just started working on ADC10 using ez430-RF2500. I tried to get values directly from the output of an amplified signal however it looks so different from the value displayed on the oscilloscope. I was supposed to get an ECG signal. Do i need to connect the ground reference to the ground used for the ecg signal?

Just curious... when is ADC10Busy (on an MSP430F1232) supposed to be set? I figured it would only be set when the ADC was actively in the middle of a conversion, but it appears to be set any time the ADC10 is merely enabled if you have it set up for a repeated sequence of conversions (but it's presently just sitting there waiting for the sample trigger source to go active).
