Not sure if I am reading the users manual correctly for the LPC1837...

Concerning sharing DAC and ADC0, if I am using the DAC on pin B2, is the ADC0_0 unavailable on package position C2.  I am using the LBGA256 package.  

Thanks

Hi Tony,

You are correct, the use of the DAC blocks channel 0 of both ADC0 and ADC1. The reason is that the ADC0_0/ADC1_0/DAC pin hardwires them all together.


Hope it helps!

Thanks Carlos.

I would have replied sooner but I guess I was looking in the wrong place.  Thought I posted in the LPC1837 section but guess I messed something up when posting.
