alxAdc_McuLpc80x - Investigate impact of ADC_DoSelfCalibration, seems like we need to configure ADC clock to 500 kHz prior calibration.. #74

Open tomazvidovic opened 8 months ago

tomazvidovic commented 8 months ago 
    // Calibrate ADC
    #if defined(ALX_LPC84X)
//  while(ADC_DoSelfCalibration(ALX_ADC_LPC8XX, (CLOCK_GetFreq(kCLOCK_Fro) / CLOCK_GetClkDivider(kCLOCK_DivAdcClk))) == false) {}   // TV: TODO seems like we need to configure ADC clock to 500 kHz prior calibration..
    #endif

Do we need to calibrate to reach "good enough" accuracy?
