Will this mess up using SCLK? * ADS-Pin03-SCLK to Artik-Pin39-XGPIO28 ** Intent: This will cycle the clock on the ADS to instruct it to bit shift? * ADS-Pin07-A1 to Artik-Pin20-GND ** Intent: There will never be more than two sets of bridges to read in this design. Set to 0 so that ADS-Pin08-A0 will always select between two MUX inputs vs. four MUX Inputs. * ADS-Pin08-A0 to Artik-Pin58-XGPIO12 ** Purpose: This will select the MUX for which bridge input is being read * ADS-Pin28-DOUT to Artik-Pin68-GPIO1 ** Purpose: For the Artik board to read in the digital hi\low signals from the ADS1234 * ADS-Pin26-PDWN to Artik-Pin##-GPIO2 == Code Design == === Methods \ Functions === * EnterPowerDownMode ** Description: This method will set the Artik pin tied to PDWN low, and should be the last interaction with the ADS1234 pins from Artik until it is ready to read the weight of the scale again. This mode offers significant power savings over StandbyMode on the digital power side of the chip [[Category:Bees]] <!--MAKE AS MANY CATEGORIES AS YOU NEED-->
