ADC startup time for S32K3

I'm using S32K3 ADC, and my test found that it takes about 30ms from powering up to initialize the ADC, performing calibration, turning on conversion, and completing the acquisition for the first time, is this normal? How to shorten this time?

Re: S32K3的ADC启动时间

Hi

RTD Quality packages的ProfileReport.xlsx列了各个APIs的执行时间。 (比如...\SW32K3_S32M27x_RTD_R21-11_5.0.0 _D2410_QualityPackage\ADC\RTD_ADC_ProfileReport.xlsx)
建议检查一下具体是哪个函数的执行时间过长导致的。
另外请问Adc_Calibrate的返回结果是什么?如果超时了的话,建议修改超时设置:
