stm32-speech-recognition-and-traduction is a project developed for the Advances in Operating Systems exam at the University of Milan (academic year 2020-2021). It implements a speech recognition and speech-to-text translation system using a pre-trained machine learning model running on the stm32f407vg microcontroller.
STM32F407 connected with LCD and four buttons that works as a simple clock. LCD and microcontroller are connected through 16 pins, LCD.c contains functions written to operate display connected that way.
Using RTC with LSE at STM32F4Discovery board (stm32f407vg). Output in display oled 0.96" 126x64 (ssd1306) by I2C interface. Timer 6 interrupt used for update lcd screen. On stm32f4discovery board you need to set X3 crystal (32768 Hz) and C16 and C22 (6.8pF). If you havn't X3 crystal you should edit the code and set LSI using in RCC section.
