WebThe rate at which an ADC converts the continuous analog signal to digital data is called “Sampling Rate”. And if it takes Ts time to convert a single sample, then the sampling rate of this ADC is Fs = 1/Ts. Then the original analog signal can be reproduced from the discrete-time digital values by mathematical interpolation. WebThe event used to start conversion can be generated by software or by the STM8 microcontroller's internal timer 1 (any type of timer event can be used). The start of A/D ... ADC conversion can be triggered by a Timer1 TRGO (trigger output) event or by a rising edge on the ADC_ETR external pin. Conversion can also be triggered by software, by
