Arduino Core for the ATMEGA4809 CPU
In official AVR Arduino core, delay() is based on yield(), which is turn has weak binding and is overridable. I am asking that delay() on any Arduino platform must call...
Just for information, I've updated original TimeLib.h library for use with internal RTC clock of Arduino Uno WiFi rev 2 https://github.com/goodchip/Time Examples here: https://github.com/goodchip/Time/tree/master/examples/TimeInternalRTC **Features:** - use internal RTC circuit...
Hi, I have no idea if this is the right place to post this issue. If wrong, just delete it, my apologies. I have posted it on arduino.cc and haven't...
While the original Uno is advertised to support Serial baudrates down to 300, it seems the m4809 can only support baudrates down to 2400. This is due to the design...
It seems like the second argument of digitalWrite is expecting a constant from `PinStatus`. However this isn't always ideal, and we get an ugly warning like shown below when this...
The Arduino Boards Manager automatically executes the `post_install.sh` script during installation of the platform on a Linux machine: https://arduino.github.io/arduino-cli/dev/platform-specification/#post-install-script This platform's post-install script is intended to create a [**udev** rules...
Today I ran into an issue while implementing a PMBus interface on an Arduino every. PMBus derrives from SMBus which uses I2C and ultimately TWI. From System Management Bus Specification...

When attempting to use initVariant() in a library I'm creating for the Arduino Nano Every I was getting linker errors about multiple definitions of the initVariant function which is weakly...
