Hi, so we are seeing a board-to-board variation on the ideal value for the Vdac for the Voltage Reference Source for the Capsense CSD component, ver 3.50. Is there some way in software to change this value? The settings are as follows:
Current Source: IDAC Sourcing
IDAC range: 255 uA
Number of bleed resistors: 1
Digital resource implementation: UDB Timer
Voltage reference source:
(*) Vdac 130 (2.08 V) --------> This value needs to be difference for different boards due to unit-to-unit variation.
Is there some software API or register to write to that can change this value?
Thanks!

Hi mish_288636
You can use the CapSense_VdacRefCH0_SetValue() API to set the VDAC value. It accepts a parameter that is the VDAC code (from 1 to 255) which corresponds to the VDAC value.
Thanks and regards
