Square Wave Voltammetry

HI,

  You may refer to (+) AD5940/AD5941 for portable device - Q&A - Temperature Sensors - EngineerZone (analog.com)

The same code snippet can be used for ADuCM355 as both use the same library file.

okay, thankyou

I am getting index and current only through realterm. I am not getting potential in square wave voltammetry techniques. please help to solve this problem.

Hi,

 The ADC mux inputs in SWV example code must be modified to add VCE and VSE voltages as described in link above:

AD5940_ADCMuxCfgS(ADCMUXP_VCE0, ADCMUXN_N_NODE)

in order to measure voltages.

Thankyou 

Hi,

I am using ADUCM355QSPZ.

To measure the voltages in SWV, I have modified SWV code as

AD5940_StructInit(&dsp_cfg, sizeof(dsp_cfg));
dsp_cfg.ADCBaseCfg.ADCMuxN = ADCMUXN_LPTIA0_N;
dsp_cfg.ADCBaseCfg.ADCMuxP = ADCMUXP_LPTIA0_P;
dsp_cfg.ADCBaseCfg.ADCMuxP = ADCMUXP_VSE0;
dsp_cfg.ADCBaseCfg.ADCPga = AppSWVCfg.AdcPgaGain;

But still, I am not able to measure voltages. Is it right, or need to modify something else? Please help.

Hi,

   I am not sure what your voltage input pins are.

Why is ADCMuxP assigned two times? Only the last assignment gets implemented on device.
