Crossware adds support to Atmel microcontrollers
Crossware Products
Atmel AT91SAM3U microcontrollers
Crossware, an embedded software tools developer, has enhanced its ARM Development Suite, adding support for the Atmel AT91SAM3U family of ARM Cortex-M3 Flash microcontrollers (MCU).
The Atmel AT91SAM3U integrates a 480Mbps USB device and transceiver; four-bit 192Mbps SDIO/SD card 2.0; eight-bit 384Mbps MMC 4.3 host and 48Mbps SPI interfaces on chip.
SAM3U is suited to applications with intensive communications requirements, such as high-speed gateways in industrial, medical, data-processing and consumer applications.
The enhancements to Crossware's ARM Suite provide a combination of wizards, simulation, debugging, compiler extensions and pre-configuration.
This allows the developer to use the C/C++ compiler and other tool-chain components and simplifies the setting up of a SAM3U chip.
Crossware's Code Creation Wizards are provided for all the SAM3U on-chip peripherals and many are able to generate configuration code and outline interrupt handlers.
The simulator simulates the Cortex-M3 core and the nested vectored interrupt controller (NVIC), as well as many of the SAM3U on-chip peripherals, allowing the developer to test the code created by the wizards.
The simulator can also be extended using the Crossware Virtual Workshop Interface, allowing developers to construct a simulation of their complete target system.
The Crossware Jaguar USB JTAG interface allows on-chip debugging.
This connects to the standard ARM 20-pin JTAG connector allowing the Crossware source level debugger to drive the on-chip ARM Serial Wire/JTAG Coresight debug port.
Firmware specific to the SAM3U will be automatically downloaded to Jaguar when the developer switches to debugging a SAM3U-based target board.
