As I want to bypass the PGA to change the input signal range from +/-2.5 to 0/5 V range.
I have taken the reference of example given in this library.
I have interfaced protocentral-ads1262-32-bit-precision-adc-breakout-board with Arduino Ethernet Board.
In example, I have put #define VREF 5 but it shows the double the input voltage in serial window and when I put VREF 2.5, it shows regular input voltage.
For input voltage range 0 to 5V (single signal), I need to bypass the PGA but I dont know how to do it.
When the input signal is more than 2.5V then it always give the 2.5V only. If the input signal is, say 4.86V then it should give 4.86V but its gives 2.5V.
Secondly, I dont want to use Power Down/Reset pin, to reduce the total number of pin, can I ignore it??
