We will set up a code in which STM32 Blue Pill will echo back the received bytes to the sender using UART RX interrupt. The code will echo back whatever it will receive on the Rx pin to the terminal. In other w

The code example for IWDG and the setup for it is very simple. A LED connected to PC 9 remains off until a push button connected to PA9 is pressed. This indicates initialization stage. Once pressed and held, the LED starts blinking, indicating normal operation. When the button is released...

6. Run the example: each time the USER pushbutton is pressed, the LED2 toggles (for more details, refer to the example readme file). To open, build and run an example with the supported toolchains follow the steps below: • EWARM a) Under the example folder, open \EWARM...
Example of computation of the energy provided to the MCU during the power-down phase: If the sum of decoupling capacitors on VDDX is 10 µF and VDD drops below 1 V while VDDX is still at 3.3 V, the energy remaining in the decoupling capacitors is:...
