Hello Atmel Community,
This is my first experience with Microchip studio. I've been starting a project where I need a single wired UART connection.
The microcontroller I'm using is the SAML21E18B. As found in the datasheet it should be able to use this functionality.
To start a project in Atmel Studio I'm using Atmel Start. There is no way I can find to use UART in half duplex mode.
Also I'm wondering how to set the clock of the microcontroller to 48MHz. I want to configure the microcontroller such that it uses the 48Mhz clock speed when it needs performance, for the other tasks I'm planning to only use the LP internal oscillator. How to fix the explenation mark for the 48MHz oscillator. Should I add an external oscillator for these frequencies?
