The ATmega4809 microcontroller in the Arduino Nano Every is no longer loaded via a bootloader program, but instead uses a single wire programming interface, Unified Program and Debug Interface, or UPDI. This also has debugging capability, but this is not available with the Arduino IDE. The ISCP interface (and its 6-pin header) is no longer …

Using the Arduino Library, a pin (here digital pin 13) can be pulsed at maximum rate with: void setup() { pinMode(13, OUTPUT); } void loop() { digitalWrite(13, HIGH); digitalWrite(13, LOW); } On a Nano, the pulse width is 3.2µs with a period of 6.7µs. On the Nano Every, the pulse width is …
I just received two Arduino Nano Every boards with the ATmega4809 microcontroller. Here are my first observations studying the boards. Next post I will show how I am handling the digital I/O pins and will talk about the compatibility layer that (attempts to) makes the Nano Every behave like a Nano. The Arduino Nano Every …
Far Inside The Arduino is aimed at users of ATmega328P and ATmega2560 microcontrollers. These include the Arduino Uno, Nano, and Mega boards. Some Arduino boards feature other AVR microcontrollers, particularly the ATmega32U4 and the ATmega4809. The ATmega32U4 is found in the Leonardo, Micro, Yun and some other boards. This chip has a build-in USB controller …
SEO! It used to be all you needed was a cleanly laid out website to get good placement in Google Search. No more. Now the site needs to be tailored for what Google wants to see. Gotta use HTTPS. Even if there is no reason to have a secure connection, and there certainly is no …
Illustrations in my recent books use a font that I purchased years ago for my teaching, Museo and Museo Sans. Back then I wanted something that would look distinctive and eye-catching (yes, I wanted students to read the handout) while being readable and easy on the eyes. The rounded elements really stand out. When it …
