Evaluation Board • ISP Experimentalboard •
The ISP test board was developed specifically for education and training in companies, institutions, and for private electronics hobbyists. The board offers on-board ISP microcontroller programming via the serial (COM) port, a variety of inputs and outputs as well as sensors to cover the complete evaluation and training spectrum.
The sensors employ mature amplification and filtering technology, so that the training can focus on programming the microcontroller. Switches and DIP-switches are available for inputs, and the entire spectrum of display outputs is available with the built-in LCD display (2 rows x 16 characters with backlighting), four 7-segment displays as well as various LEDs.
Ideal for educational facilities for die introduction and advanced training in:
- Mikrocontroller technic
- Mikrocontroller programming
- LCD control
- Machine contrlol
- Sensor technology
The current version of the Prog-Studio 6 software is available online and contains a selection of sample programs for the components on the ISP Experimenting Board. There are also several samples on the version of Prog-Studio 6 that is included on CD.
The samples can be found in the subfolder “Samples” after the Prog-Studio 6 software is installed. All programs developed specifically for the Experimenting Board start with “ISP”.
The selection of sample programs will keep growing as further programs are being developed.
The Atmel Flip software or the Batronix Prog-Studio 6 software can be used to program the microcontroller.
Here are some sample programs and experiments which are possible to implement with the board directly: running lights, running texts, counters, controlling of 7-segment displays, controlling of LCD-displays, measuring of voltages, luminance and temperatures, standardisation of measured voltages from one sensor in a physical unit, reflex-light barrier, stopwatches, clocks, alarm clocks and weatherstation.
Components on the ISP Board
Microcontroller and programminginterface:
- The Atmel Flip software or the Batronix Prog-Studio software can be used to program the microcontroller. The programming cable is a part of the set (connect to COM1 to COM4).
- T89C51AC2 Microcontroller with max. 20MHz in x2 Mode (equals a standard 8051 Microcontroller mit 40 MHz!).
- 10 bit AD-converter with 8 channels
- 32K Byte Flash, 256 Byte RAM
- 1K Byte on-chip XRAM
- 2K Byte EEprom
- 2K Byte Bootloader
Optical elements:
- LCD-Display (2 rows with 16 characters), background light controlable with the microcontroller.
- Four 7-Segment displays with upstream latches (D-Latch). Every segment is freely controlable (display is not limited to digits). No multiplexing because of the latches!
- Eight LED Lights with upstream latch (D-Latch). Only low-current LEDs with low power consuption and high quality are used.
Sensors:
- Lightsensor BPW34 with downstream adjustable amplifier (Factor 1, 10, 100, 1000) and low-pass filter.
- Infrared LED LD271 and Infrared diode SFH205 mit downstream amplifier and high-pass filter. These parts are arranged as reflex light barrier.
- Temperature sensor KTY81-210 for the measuring of temperatures between -55°C and +80°C (+-1%).
- Potentiometer to simulate a voltage measuring.
Input elements:
- Four keys for free use (arranged like cursorkeys).
- Four DIP-switches for free use.
- Six DIP-switches to connect the sensor- or op-amp outputs to the portinputs of the microcontroller. With these switches you can free the portpins for use with other applications.
- Two DIP-switches for light-sensor op-amp adjustment. You can set the amplification factors to 1, 10, 100 and 1000.
- Two keys for Reset and PSEN signals.
Additional output elements:
- Buzzer TDB05 for acoustical signals (2.3 KHz, about 85dB).
- Two "Expansionports" for control of Extensionmodules (P1, P2).
