Hi Team SimpleLink,

Reference (http://e2e.ti.com/support/microcontrollers/msp430/f/166/t/692127 ) .  Has this issue been fixed?

Thanks, Merril

    Merril,
    This feature has not been added. Effectively this would be a scatter-gather implementation of the uDMA on the MSP432P4111 device. How many channels are being measured, what is the sample rate, and sample size?

    Sample size assumes a 'ping-pong' type of implementation that means after N samples of each channel a processing thread would start while the next N samples of each channels begins. This example is written in driverLib but conceptually gives an idea.
