Atmel – Touch and segment LCD control made easy with new SAM L22 Atmel Xplained Pro MCU development kit


The new SAM L22 Atmel Xplained Pro development kit is a professional evaluation board featuring an on-board debugger and standard extension connectors.

The SAM L22 Xplained Pro kit is fully supported by Atmel Studio, a free integrated development environment which features power profiling tools for the SAM L22 board. These make it easy to optimise applications and to calculate average power consumption. Application examples in the Atmel Software Framework are provided with the kit.
