1. DARREN'S PROJECT PRESENTATION 8051 Controlled Speedo For a Trolley On An Inclined Ramp

2. Background: Technology Being Replaced  Outgoing technology includes:  Bulky DC Power Supply  Optical Sensor  Portable Digital Scope  Pen, Paper & Calculator

3. Background: Spec provided.  Design Spec. provided by ANECTO Ltd.  Simple device set-up  User friendly display module  Idiot-proof operation  Easily verified output (by operator if possible)  Clear & concise documentation

4. Operator Time Optimization  Replacement device will eliminate slow & unreliable operator calculations  Faster test set-up  Errors will be avoided  Reduced cost to the paying customer

5. Main Technologies Employed  8051 Microcontroller  SX-461 Opto-switch  LCD Display  Capable of independent operation  System to be expanded to relay it’s readings to PC  Serial or USB? Reliability Issues? Connectivity?

6. 8051 Development Board  62 Kbytes On-Chip Flash/EE Program Memory  Sufficient for reasonably large source code  Built in Interrupt based timer  Can be configured for 16-bit operation  On-board Serial communications

7. PC Based User Interface  System to receive data from core test unit  Data from various tests to be stored & easily accessed  Statistical analysis to be carried out on acquired data  PC Interface to transmit calibration data back to the core test unit

8. Research & Implementation Goals  Re-acquaint myself with the 8051  Implement & test all basic functions required  Much of the code design is completed  Construct a standalone, fully enclosed unit ready for initial use & testing (ASAP)  Testing of Serial/USB functionality thereafter  Finally, a PC based application will be constructed

9. Goals (Monthly)  November  Installation of the basic unit for parallel operation with existing system  December  Functional system in place & verified  January  PC based application to be complete & in testing  Febuary  System complete & write-up underway

10. Review Schedule  Reviews may be at any point you wish  Weekly e-mail will detail progress  Full review after each major milestone

11. Contingency for Change of Plan  There will be several months available for tidying up the code & hardware towards the end of the project  If a deadline is overshot the time will have to be made up ahead of the next one

12. Initial Strategy 1. Construction of the Development System as a test- bench unit  8051 Dev. Board & PSU  LCD & PSU  Optical sensor & PSU 2. Installation & test of a rudimentary unit  Integrated system with only one PSU for the core unit 3. Further development to follow

13. Closing Slide  Any Questions?
