The data is used for internal computation (peak value is computed and data is normalized - a simple Automatic Gain Control algorithm) and then transfered through a high speed SPI, using another DMA channel. The ADC is configured to converts continuously ADC1 channel14. Each time an end of conversion occurs the DMA transfers, in circular mode, the converted data from ADC1 DR register to the ADC_ConvertedValue data array. The ADC1 clock is set to 14 MHz. When half of the data buffer is available, we parses the array and normalises the values in the array (the peak value is set to 0xFFFF). Once the normalisation is completed, the SPI is used to send the results externally.
