Not sure about the differences in devices. I'll need to double check data sheets about clocks and such. My next debugging steps is to break out a logic analyser to compare the two scans. I'll post again with results.

I should also share code version info:

MicroPython v1.8.4-40-g7ea3fa2-dirty on 2016-09-20; PYBv1.0 with STM32F405RG

I'm trying to use machine.I2C on a PyBoard, but I'm getting some interesting results when scanning the bus for devices. I have a number of devices attached. Using pyb.I2C and the default settings for I2C, I get: [39, 44, 72, 73, 90]. When I try this with machine.I2C, I only see a subset of those dev...

I've noticed, using the code below, that there is an offset between the readout and the DAC buffer. I guess this is to be expected, as there is no trigger to synchronise the star...
