CCS/PGA900: PGA900 EVM board have no output signal

Part Number: PGA900

Tool/software: Code Composer Studio

Hi :

I am using XDS200 to do firmware debug. PGA900 EVM board has voltage output on Vout pin.

But it has no output when I do firmware debug.

I can watch that PADC data and DAC_REG all changed with input voltage.(10mv)

But when I measure the Vout pin, it has no output.

here is source code and picture of debug page.

Could you help to check what may cause this problem?

  • Hello,

    Is the TEST_MUX_DAC_EN bit set to mux the DAC output to the VOUT pin?

    Regards,
