ADC setup; where is the software related info / documents located
I am using CYBL-022001 Module, and trying to run BLE Battery Level example code that uses AtoD Converter. Problem is all example code assumes that I am using BLE pioneer board in CY8CKIT-042. and examples and documentation assume pioneer board is Jumpered J2 P3.0 to J3 Vref. Documentation in BLE_Battery_Level example says.
"When VREF is selected as reference to the ADC, and if the reference bypass is enabled, this will bring out VREF (through an internal series resistance)." This is Incredibly confusing, Is there any documentation on how the features of the ADC work? I can not see why this would be useful? Is this trying to tell me that you are supposed to be able to somehow use the chip to switch the reference around to different voltages? If so then how are you supposed to know when the output signal is actualy at the proper level. what if the reference does not dishcharge, what is the charge and discharge resistance? etc.
I must be missing some documentation? Where is the documentation on the chip, with its memory map, register map, and all that related stuff?
