I'm a bit miffed about the data type changes between Uno and Due.
I'm playing with low level ADC and DAC control via PDC in a Due.
it seems the PDC transfers data in 16-bit chunks.
however, Int is 4 bytes in Due, as opposed to 2 in Uno.
sizeof(short) is reported to be two bytes but using shorts creates strange
issues when declaring the array.
what do I do to create an array of 1024 16-bit-unsigned values in a DUE ?
I guess the uint32_t and it's kin are the new style of how to code.
worked for me (without needing to use an include file)
Still, there is something fishy in that PDC / DMA.
The DMA can transfer 1, 2 or 4 byte chunks, according to the datasheet,
but it is not clear when it is using what format.
If someone knows where i should look for that nugget of knowledge in the datasheet,
please let me know.
