 I performed a complete refactor of the core analysis functions and calibrated the system to align with reference standards. As a result, the approximation error has been reduced, achieving a high level of precision in data interpretation.

+I added the possibility to switch between pages, adjusted the sizes of the objects on the screen. Also, the touch possibility was successfully added and properly tested.

+Changed the formula for the SpO2 calculation. Fixed the timer and the display of the pulse graph. Minimised the pulse uncertainty as much as possible. Finished the project.

 ## Hardware
 
 The hardware architecture of PulseOx utilizes an STM32U5 microcontroller as its high-performance processing core. Physiological sensing is handled by a MAX30102 high-sensitivity optical sensor, capturing both heart rate (BPM) and blood oxygen saturation (SpO2). The system features a TFT ST7789V display for real-time data visualization, capable of rendering complex signal waveforms alongside numerical measurements. User interaction is enhanced through an active buzzer for synchronized audio feedback and a tactile button interface for seamless measurement control.
