Installation USB Flash Drive for IAR Systems Embedded Workbench® for ARM, version 7.1 or greater. See installation guide “Holt IAR and Demo project installation guide” for important instructions.
Plug-in 5V DC power supply.
USB debug interface cable.
RS-232 serial cable, DB-9M to DB-9F for console I/O using a connected computer.
2-board assembly comprised of:
Upper TARGET board with HI-35981 device and HI-8597 ARINC transmit driver.
Lower MCU board with ARM Cortex M3 16-/32-bit microprocessor, debug interface and regulated 3.3VDC power supply.
The detachable TARGET board can be separated from the provided MCU board for connection to a user-supplied alternate microprocessor or FPGA board. The inter-board headers are located on 0.1” (2.54mm) grid for compatibility with generic prototyping connectors and boards. All host interface signals go through the inter-board headers.
The lower ARM Cortex M3 MCU board is based on the flash-programmable Atmel AT91SAM3U-EK microprocessor. The Atmel processor 4-signal Serial Peripheral Interface (SPI Master 24MHz) using NPCS0 configured as a GPIO pin connects to the HI-35981. A UART-based serial port provides RS-232 console I/O (optional). An uncommitted USB 2.0 port is available for future or customer expansion.
