Hi Hans! First let me say that I have no Pocket and cannot speak about experience, but only about knowledge that I've read anywhere.
As far as I know the PocketBeagle has a CPU with inbuild memory, but fully compatible to the AM3358 (which I use). My guess is that the ADC measurent is equal at both systems (untested), which gets done by the TSC_ADC_SS (= Touch Screen Controller_Analoge Digital Converter_Sub System). That subsystem is designed to measure touch screen input, and the measurent isn't very accurate. Anyway, you should see 12 bit resolution. But note, libpruio may left shift the raw data in order to make them comparable with 16 measurements. This depends on the last parameter Mds in the call to function PruIo::config() <http://users.freebasic-portal.de/tjf/Projekte/libpruio/doc/html/class_pru_io.html#ae3f7d3561ab2642dd822c41a0be63a6d>. When this parameter is 0 (zero) you'll get unchanged data directly from the TSC_ADC_SS. This should be in the range of 0-4095 with one bit resolution. Find further details in the libpruio docs <http://users.freebasic-portal.de/tjf/Projekte/libpruio/doc/html/ChaFeatures.html#sSecBitEncoding> and in the CPU TRM chapter 12 <http://www.ti.com/lit/pdf/spruh73>.
