Tool/software:
Hello.
Setting up ADC conversion with sys cfg.
No matter what time I put in the desired sample time, the total ADC conversion time - sample window + conversion window - never changes.
The way I am testing (approximate conversion) time is:
DL_ADC12_enableConversions(ADC12_0_INST);
DL_ADC12_startConversion(ADC12_0_INST);
if((adc_status=DL_ADC12_getStatus(ADC12_0_INST)==0x01)) // test for busy bit
count++;
Even with sample time of 100 us, count only ever gets to one.
Note from manual:
10.2.13 Status Register
The ADC status register, STATUS, contains two bits – REFBUFRDY and BUSY.
• •
REFBUFRDY is set when the ADC receives the ready signal from the internal reference buffer (VREF/ REFBUF) after asserting the enable request
BUSY equaling ‘1’ indicates that the ADC is busy performing a sample or convert operation
Two snips from sys cfg attached.
Thanks.
Phil
