- The STM32F103C8 can deploy half of its clock speed for ADC sampling - by setting the prescaler to 2, see RCC_ADCPRE_PCLK_DIV_2 - and computes
**FFT**for 1024**samples**in 2 ms. The sampling capacitor is allowed to charge in 1.5 ADC cycles using the ADC_SMPR_1_5 setting and the**sample**quantization takes another 12.5 ADC cycles to complete. - Example Example below works on STM32F429-Discovery board. This board has LCD on it, so it can be also a little bit graphical. Provides you a

**FFT**) application developed using a low-power microcontroller that includes a single-cycle hardware multiplier. The application computes, in real-time, the spectrum of an input voltage (V IN in Figure 1). To accomplish this, an analog-to-digital converter (ADC)**samples**V IN and transfers the. - Oct 23, 2014 ·
