LOW PASS FILTER USING STM32F401RE NUCLEO BOARD
Objective: Implement a Low-Pass Filter (LPF) on the STM32F401RE Nucleo board. The system will utilize an internal push-pull button to start and stop signal acquisition from the ADC, as well as the filtering process. Additionally, an internal LED will be incorporated to indicate the current status of the system, where the LED being ON signifies that the filtering process is active. The input signal for the filter will be provided by a function generator. The TIM1 timer will be configured to achieve an exact sampling frequency of 256 Hz, with a filter cutoff frequency set at 3 Hz.
