Convert ADC Code to current in Amperometric measurement

Hi,

1) After each measurement, you can change ADC PGA gain by updating it inside AppAMPRegModify() function by including below lines in it:

 DSPCfg_Type dsp_cfg;

dsp_cfg.ADCBaseCfg.ADCPga = new PGA gain value;

AD5940_DSPCfgS(&dsp_cfg);

2) RtiaCalValue.Magnitude is the magnitude of calibrated value of internal RTIA resistor ( feedback resistor of LPTIA). 

This calibration is done by AppAMPRtiaCal() function.

 AppAMPRtiaCal() function needs RTIA value input from user which is set by AppAMPCfg.LptiaRtiaSel.
