hi, all
i am working on lpc1768 adc now, and the code to do the polling of adc works.
and then i want to use the power down of adc to minimize the current,
so i set the PDN bit(ADC_PowerDownCmd) before the adc function and clear it after adc.
i fount that the ADC_ChannelGetStatus function returns zero after ADC_StartCmd.
why? how can i let adc go to power down mode and repower it up before adc sampling?
any help is appreciated.
