    Hey @@simpleavr, the datasheet of the msp430g2553 says the ADC is capable of "up to 200ksps", that means, a 10Khz signal will have only 20 samples of resolution (at max sampling speed) for a complete wave (so it is not gonna look smooth at all) . So a 200KHz signal should seem like a square wave . But that wouldn't be helpful nor reliable for signal viewing. I don't know why the limit is at 200ksps and I don't know what would happen if you try to sample at , say, 1Msps, using the 16Mhz config. Since I am using the burst mode (with the DTC) I don't know either if the msp430g2553 will let

    I needed to be able to watch signals from hundreds of Hz to 10Khz . While reading the msp430 family manual found the Data Transfer Controller (DTC) that can be put to work with the ADC . So the original launchscope by NJC streams data one sample at a time , and that is why it is so slow . So using the DTC we can actually get near the 200Ksps . So I use an array of 200 integers (400 Bytes . I didn't want to leave the launchpad without ram, just 512B for the msp430g2553
