Figure 15-3. Blue Earth’s Micro440 board has BASIC-52 and a monitor program in a tiny package.
Micromint offers a variety of 8052-BASIC boards and other products. Both the BCC52 and RTC52 are single-board systems that can also serve as the base of an expanded system. The BCC52 uses edge connectors and a backplane, while the RTC52 is a stackable design. A variety of expansion boards are available, including interfaces to displays, keypads, relays, infrared control, and A/D converters. The BRUTE-52 is a single board with many expansion options on-board.
Micromint’s Domino is a complete Basic-52 system in a 20-pin encapsulated package that’s about the size and shape of a domino. It has a surface-mount 80C52-BASIC chip, 32 kilobytes each of RAM and EEPROM, and twelve I/O pins, two of which may be analog inputs. The Domino’s BASIC-52 interpreter adds functions for measuring frequency and period and for reading the analog inputs.
Prologic Designs offers an inexpensive bare pc board (Figure 15-2) and detailed manual for 8052-BASIC systems, for those who prefer building their own.
Blue Earth Research’s Micro-440e is a complete system on a tiny pc board, just 1.9" x 2.25" (Figure 15-3). The system uses a surface-mount 83C51FB chip with both Blue Earth’s version of BASIC-52 and a monitor program in ROM. A case and expansion boards are also available. The Micro-485 adds an analog-to-digital converter, clock and calendar, and an RS-485 interface for networking.

Chapter 15
To speed up program execution, you can use Dallas Semiconductor’s DS80C520 high-speed microcontrollers, which are compatible with the 8051 family. MDL Labs and Photronics Research offer variations of BASIC-52 designed for use with these chips.
BASIC-52 Source Code
If you’re interested in seeing the source code for the BASIC-52 interpreter, look for it on Intel’s or Philips’ BBS or on the Internet (Appendix A). To modify the code, you’ll need Intel’s ASM51 or a compatible 8051 assembler.

Sources
This Appendix lists a variety of sources to help you in your 8052-BASIC projects, including books, on-line BBS’s, and companies who offer products related to the topics in this book.
Books
Here is a selection of books about BASIC-52, the 8051/2 microcontroller family, and related topics:
BASIC-52 Essentials
These are the essential hardware and software manuals for working with the 8052-BASIC. You’ll need either Intel’s or Systronix’s programming manual, and a data book from Intel or another 8052 vendor. See the Product Vendors section for addresses and phone numbers.
BASIC-52 Programming
Systronix $20 postpaid
Complete reference to the BASIC-52 programming language. Includes many program examples and handy back-cover index.

Appendix A
BASIC-52 User’s Manual (Intel #270010-004 $15
Complete reference to the BASIC-52 programming language. Includes some circuit schematics.
Embedded Microcontrollers Handbook (Intel) $22.95
Intel’s handbook, or data book, has hardware details and an assembly-languuage reference for the 8052 and 80C52 (and much more), but nothing specifically about the 8052BASIC chip. Intel updates the data books yearly, so the exact title and price may vary. Ask for the data book that covers 8-bit embedded controllers. Philips, Siemens, and other manufacturers also publish data books for their 8052 and 80C52 chips.
8051/2 Microcontrollers
These are some additional books about the 8051 family of microcontrollers. The Product Vendors list has addresses and phone numbers for many of the publishers. Local bookstores can order the others, which are from major publishers.
Assembly Language Programming (L.S. Electronic Systems, 190 pages, $33.00). For the 8051 family.
C and the 8051: Programming and Multitasking, by Thomas W. Schultz (Prentice Hall, 1993, $52). Discusses using an operating system to handle multiple tasks. Examples include solenoid cyclers, a pulse generator, envelope detector, and motor speed control, using the C programming language.
The 8051 Family of Microcontrollers by Richard H. Barnett (Prentice Hall, 1995, 164 pages, $49)
The 8051 Microcontroller, 2nd edition, I. Scott MacKenzie (Macmillan, 1994, 356 pages, $58). Includes schematics for a single-board computer, assembly-language source code for a monitor program, and interfaces to a keypad, LEDs, and loudspeaker.
The 8051 Microcontroller: Architecture, Programming, and Applications, Kenneth J. Ayala (West Publishing Company, 1991, 241 pages, $49). Includes disk with assembler and simulator.
The 8051 Microcontroller: Hardware, Software, and Interfacing, James W. Stewart (Regents/Prentice Hall, 1993, $27.50, 273 pages). Includes many interfacing examples, such as switches, solenoids, relays, shaft encoders, displays, motors, and A/D converters, and a chapter on top-down design method.

Data Books
Data books are where to look for specific, detailed information about a particular IC. They’re also a good source for application examples. National Semiconductor has a good selection of books covering most types of integrated circuits. The exact titles and prices change from year to year, but this is a typical selection:
CMOS Logic (including HCMOS, HCTMOS, 4000 series, 74C series) TTL Logic (including LSTTL)
Linear Devices (A/D, D/A, temperature sensors, voltage references)
Op Amps
Power ICs (voltage regulators, peripheral drivers)
You can request data books directly from the manufacturers. Digi-Key and other component vendors also offer a selection. For a small charge, many suppliers will include data sheets for individual components that you order.
