The STM32F429I board was programmed with GNAT Programming Studio 19.1 Developed by AdaCore. This part develops the most important control function of the system and I will detail below. The schematic diagram and the flowchart you can get at the end of this tutorial. As a reference for this project, I've used the following Ada tools:

• 1) examples such as demo_adc_polling, and demo_gpio_direct_leds;
• 2) Ada drivers libraries like STM32.User_Button, STM32.ADC, STM32.GPIO, and LCD_Std_Out; and
• 3) Theory sucha as arrays, and for and while loops.

The analysis of the code of the digital blood pressure monitor I've divided it into three sections:

• Inflation of the cuff,
• Deflation of the cuff, and
• Calculation of the Korotkoff sounds.

Our schematic diagram is shown below:
