Atmel Ecosystem


Each successive product generation typically requires more software but engineers must continue to maintain quality and development schedules despite these more complex devices. Atmel provides free development software and easy-to-use evaluation kits to help streamline the design process. With Atmel® Studio Integrated Development Environment (IDE), designers have access to advanced code editing features, project examples, an integrated embedded software platform, and powerful debug integration capabilities. Atmel Studio provides full support for all Atmel MCUs, so you won't have to switch between different IDEs when developing with different Atmel devices. Atmel also works with an ecosystem of partners worldwide to provide additional hardware, development tools, RTOS, middleware and software solutions to deliver an easy-to-use integrated development platform to help you move quickly from prototype to production.
