Crossware Enhances 8051 Trainer with Flash Microcontroller and Debugger.Business Editors/High-Tech Writers CAMBRIDGE, England--(BUSINESS WIRE)--Feb. 13, 2003 Crossware(www.crossware.com), a leading embedded software Instructions that permanently reside in a ROM or flash memory chip. Embedded software may be immediately available to the CPU or, for faster execution, may be transferred to RAM first and then executed. tools developer, has enhanced the 8051 based FLT-32 Microcontroller Trainer with a new software suite and a modern flash programmable Atmel chip to make it a state-of-the-art system for teaching modern embedded development techniques. The FLT-32 Microcontroller Trainer, first introduced by Flite Electronics (www.flite.co.uk) in 1990, is used to teach microprocessor and control principals to electronic engineering and computing students worldwide. The system incorporates a standard 8032 microcontroller and a text based command line monitor, which allows students to download and run programs from a host PC. Numerous application boards are available that connect to the Trainer allowing a range of sophisticated experiments to be performed. The Crossware enhancements include an upgrade from the original 8032 chip to the modern Atmel T89C51RC2 microcontroller, which includes 32k bytes of flash programmable memory. Switching to the superior T89C51RC2 leaves the Trainer 100% compatible with the original system and thereby avoids any changes to existing teaching courses. Other enhancements include additional peripherals such as a five channel program counter array (PCA (tool, programming) PCA - A dynamic analyser from DEC giving information on run-time performance and code use. ), serial peripheral interface (communications, hardware) Serial Peripheral Interface - (SPI) A serial interface in which a master device supplies clock pulses to exchanges data serially with a slave over two data wires (Master-Slave and Slave-Master). (SPI (1) (Stateful Packet Inspection) See stateful inspection. (2) (Service Provider Interface) The programming interface for developing Windows drivers under WOSA. ), keyboard interrupt interface, hardware watchdog timer, and enhanced Universal Asynchronous Receiver/Transmitter (communications, hardware) Universal Asynchronous Receiver/Transmitter - (UART) An integrated circuit used for serial communications, containing a transmitter (parallel-to-serial converter) and a receiver (serial-to-parallel converter), each clocked separately. (UART (Universal Asynchronous Receiver Transmitter) The electronic circuit that makes up the serial port. Also known as "universal serial asynchronous receiver transmitter" (USART), it converts parallel bytes from the CPU into serial bits for transmission, and vice ) with a dedicated baud rate generator and automatic address recognition. A new programmable array logic (hardware) Programmable Array Logic - (PAL) A family of fuse-programmable logic integrated circuits originally developed by MMI. Registered or combinatorial output functions are modelled in a sum of products form. (PAL) from Flite Electronics also preserves the backward compatibility of the Trainer and provides additional addressing logic, which allows programs to be run from the microcontroller's internal flash memory. Programmed into this memory is a special version of Crossware's debug To correct a problem in hardware or software. Debugging software means locating the errors in the source code (the program logic). Debugging hardware means finding errors in the circuit design (logical circuits) or in the physical interconnections of the circuits. monitor. In conjunction with the Crossware 8051 Training Suite running on a host PC, this debug monitor supports full source level debugging. Furthermore, by using the internal baud rate generator to drive UART communications with the PC and by using a PCA timer to control single stepping, the debug monitor leaves all three of the standard 8052 timers available for the user - two more than available with the original software monitor.
