Anybody know how to confirm the adc speed in burst mode?
I tried polling a done bit in the control register.
If done == 1 read corresponding data register and toggle a pin.
The results are not cyclic.
Doesn't look like the done bits are used in burst mode.

Anybody know anything about this?

Thanks

Thanks for the reply tha.

Your suggestion worked.
For some reason I didn't think interrupts could be used with burst.

The simplest way would be to use the ADC sample code from the code bundle, http://www.lpcware.com/content/nxpfile/sample-code-bundle-lpc11xx-peripherals-using-keils-mdk-arm, and set the example to use burst mode with interrupt driven.  Then in the ISR handler, toggle a GPIO pin.
