Two questions... many thanks in advance: 1) Per https://www.digilentinc.com/Data/Products/TI-ANALOG-SHIELD/AnalogShield_rm_rev3.pdf, "The Analog-to-Digital input converter (ADC) and Digital-to-Analog output converter (DAC) both use the standard Arduino form factor SPI bus pins and use independent chip selects." Question: For those of us developing our own library variants, what are the CS numbers? I am not seeing this documented. Update: From the attached snippet of the schematic, and the likelihood that "CS" = "SYNC" = "SYNCN" = "CSN" = "SS" among other possible nomenclature, is CS for the ADC header pin 3, and CS for the DAC header pin 6? (Also see attached close-up of the Shield's header, which suggests pin 0 on P7 is pin 0 for the Arduino Uno at least. Note the nomenclature is clear on the screen-printing next to the header: ADCCS and DACCS.) Update: Argh! The schematic pin numbering is 1-based; the silk-screened header pin numbers on the Shield are 0-based! ...Really now, this all ought to be documented unambiguously and consistently. SO... are the pin numbers for the chip selects for ADC and DAC 5 and 2, respectively, for the Uno? 2) From the same document, "The jumper needs to be set for whether the connected board uses IOREF, 3V3, or 5V0 for the I/O for the SPI interface." Question: Which setting is needed for which supported Arduino board? That is: For the chipKIT Uno32, the jumper should be ____________For the chipKIT UC32, the jumper should be ____________ For the chipKIT Max32, the jumper should be ____________For the chipKIT WF32, the jumper should be ____________For the Arduino Uno, the jumper should be ____________ As a bonus, suggestions for determining the correct jumper setting from a schematic would be really handy.
