I am using discovery board with stm32f429.
I configured well the ADC for DMA and works fine but I don't know what is the sampling rate. Anyone can explain how to calculate it?
The clock is at 90Mhz the prescaler is ADC_CLOCKPRESCALER_PCLK_DIV8 samplingTime is DC_SAMPLETIME_84CYCLES
My calculations says that sampling rate is 46875. Is that right?

Thank you in advance for any help
