example:
adc = pyb.ADC(resolution) //resolution is not actually used yet
data = adc.read_channel(n) //where n is 0..15

What will be the recommended way to run the STM32F407 ADC's at 2.4MHz or
interleaver for 7.2MHz?

I'm not sure yet, the ADC is a beast! this driver only support a subset of the functionality, i.e. single conversion mode, no interleaved or group conversion support is implemented yet.. I'm also working on internal temperature sensor and vbat/verf readings.

The processor has the speed to handle the 2 to 7MHz data stream to a
circular buffer and do some processing to detect an event (something I need

• along with the DSP). A clean way to get to this through Python has eluded
  me so far. A PC style ISR is not very appealing but may be what works. I
  have done a lot of ARM assembly language but Thumb2 has eliminated some of
  my best tricks.

Example:

@ARMWorks I'm not sure if python callbacks are implemented yet, that would be nice to have, and I'm sure more features will be added to this driver in the future.

Python callbacks do work: just pass along a function (eg lambda) as the entity to call back.

That's very cool (although your core temp runs hot!).

BTW, if you want to get rid of the timeout errors, uncomment the mma_init() call in main.

Yes I noticed that too, according to the datasheet the offset of the temperature function varies from one chip to another up to 45 degrees! and so it's not to supposed to be used as an absolute temperature measurement, it should be used for detecting temperature variations.
