Part Number: PGA970EVM

Tool/software: Code Composer Studio

hi, i am using the pga970evm, with PGA970_FW_Release_1_6_Generic.

in “switch.h ”, WAVEFORM_TESTING=ON and WAVEFORM_10KHZ_TESTING=ON. (Nothing else is modified)

then i compile the project and get a HEX file, i download this file by USB2ANY with PGA970 GUI into FRAM.

I 'm generate the waveform, the sensor lvdt is connected, i can read adc1, adc2 with the GUI and it works fine .

but I have nothing on OUT pin13 .

if i change the value of DAC_REG0_2( Low Level configuration or High level configuration-DAC Setting),i can see the output change .

What is the problem?

Thanks for your reply,

Best regards.
