Arduino megaAVR Watchdog & Resets, e.g. Nano Every ATmega4809

The megaAVR 0-series watchdog timer and reset controller … ↓↓↓ Complete description, time index and links below ↓↓↓ A little over a year ago we’ve unlocked all four hardware serial (USART/UART) ports of the Arduino Nano Every, respectively, ATmega4809 MCU (link below). Now it’s time to have a look the watchdog timer and reset controller. We start out with the reset controller, determining which kind of reset occurred and performing a software reset. Then we move on to the watchdog timer, which we’ll use in normal, respectively, window mode and … to perform watchdog resets. 00:00 Intro – megaAVR reset controller and watchdog timer 00:36 Reset controller – datasheet and Nano Every details 08:25 Reset code – what reset the MCU & software reset 17:43 Watchdog timer (normal mode) – datasheet 19:40 Watchdog code (normal mode) – setting and resetting 25:46 Watchdog timer (window mode) – datasheet 27:27 Watchdog code (window mode) – setting and resetting 33:18 Hardware reset – pulling the reset pin low 35:15 Wrap-up Tutorials    • Tutorials   Arduino Nano Every: Four Hardware Serial Ports – Without Additional Hardware    • Arduino Nano Every: Four Hardware Ser...   My code https://drive.google.com/drive/folder... #arduino #arduinonano #avr #microcontroller #reset #tutorials #tutorial #how-to #robertssmorgasbord
