P89V51RD2 Development Board

SysKriation Innovation & Implementation Introduction: P89V51RD2 Development Board is integrated with all the basic components required for most of the 8051 microcontroller based experiments. It is made from double sided PTH PCB board to provide extra strength to the connector joints for increased reliability. Board can work on 9 to 15V DC supply. It has built-in reverse polarity protection. It has onboard 8-channel Analog to Digital Converter (ADC) ADC0808, RS232 interface with DB9 female connector based on MAX232, Motor driver L293, 7-segment display with BCD to 7-segment decoder, DAC0808, Micro-Relay with drive circuit, DIP switch, 4x4 keypad, 2-extra key, 8-LED and also 16X2 LCD connected on the board. All ports are connected to standard 8-pin female connectors. Other device interfaces are also connected to standard connectors. It can be programmed using Flash Magic programming utility of NXP’s own programming utility via serial port. There are provisions for selecting the reference voltages for both ADC and DAC and reference voltages can also be adjusted by turning the provided trimpot.

Selecting and Adjusting Reference Voltage: ADC reference can be given +5V fixed or lower by properly Selecting and adjusting the Trimpot. For +5V fixed reference set the jumper between top and middle pin and for lower reference set the jumper between middle and lower pin. However lower reference can be measured in lower pin by DMM or Oscilloscope before setting the jumper.

P89V51RD2 Development Board

SysKriation Innovation & Implementation Loading Firmware on Development Board P89V51RD2 Development Board programming involves two steps. First step is to write and compile the code and generate the “*.hex” file. Second step is to load this “*.hex” file on the microcontroller using Flash Magic software provided by NXP (formerly Phillips) We are going to use Keil-µ-Vision (Version 4) software for writing the code for the microcontroller. We can also use any other open source of proprietary software supporting P89V51RD2 microcontroller. P89V51RD2 Development Board CD contains free version of the µVision 4 software. You can also download latest version from http://www.keil.com/dd/chip/3711.htm and click C51 Evaluation Software For writing, compiling C program and generating *.hex file in Keil-µ-Vision see the tutorial provided in the CD.

SysKriation Innovation & Implementation Loading the generated Hex file on the microcontroller using Serial Port

Flash Magic is Windows software which allows easy access to all the In System Programming (ISP) features provided by the devices. These features include: • Erasing the Flash memory (individual blocks or the whole device) • Programming the Flash memory • Reading Flash memory • Reading the signature bytes • Reading and writing the security bits • Direct load of a new baud rate (high speed communications) • Sending commands to place device in Boot loader mode Flash Magic provides a clear and simple user interface to these features Go to ‘Flash Magic’ Icon, it will open the main window as show below.
