ADC - Continuous mode stops after one conversion

I am trying to use the ADC to convert continuously, but I am getting only one conversion each time I start the ADC ???

I am trying to use the ADC in 'analog watchdog' mode, monitoring a single regular channel (channel 9).

CR1=0x00800249, CR2=0x00000003

The CR2.CONT bit is set, but I only seem to get one conversion (DR, SR updated) each time I set CR2.SWSTART

Any suggestions where I'm going wrong ?

Now fixed. The following line was missing:

ADC_CommonInitStruct.ADC_TwoSamplingDelay = ADC_TwoSamplingDelay_5Cycles;
