How to Use
To begin using the Parallax BS1-IC, first establish a development environment by installing the BASIC Stamp Editor software on your computer. Connect the module to a programming board or carrier circuit with a serial connection to your computer. The module requires a stable 5V power supply with adequate decoupling capacitors (typically 0.1 microfarads ceramic and 10 microfarads electrolytic) placed close to the power pins. Before writing custom code, verify proper operation by uploading a simple test program such as a blinking LED routine to confirm communication between the editor and the hardware.
Program development follows a straightforward cycle: write PBASIC code in the editor, compile the program, and download it to the module's EEPROM through the serial interface. The interpreter then executes your program from the internal ROM, with each PBASIC command translated to machine instructions on-the-fly. For I/O operations, declare pins using the INPUT and OUTPUT commands, then use HIGH and LOW commands to control digital outputs or read pin states. For timing-critical applications, utilize the built-in PAUSE command for millisecond delays or implement interrupt-driven routines using the DEBUG command for serial monitoring and troubleshooting during development.
Product Overview
The BS1-IC operates as a complete microcontroller solution with an integrated 8-bit processor running at 4 MHz, capable of executing PBASIC instructions directly from its 256 bytes of EEPROM program memory. The module features 16 I/O pins that can be individually configured as digital inputs or outputs, with built-in pull-up resistors on port B. The architecture includes a 16-bit timer, internal oscillator, and power-on reset circuitry, eliminating the need for external timing components in most applications. Communication with external devices is facilitated through asynchronous serial I/O capabilities, allowing integration with sensors, displays, and wireless modules.
What distinguishes the BS1-IC from competing microcontroller solutions is its exceptional ease of use combined with genuine industrial reliability. The PBASIC interpreter embedded in ROM allows developers to write and test code without requiring specialized programming equipment or deep assembly language knowledge. The module operates from a single 5V power supply and draws minimal current, making it suitable for battery-powered applications. Its proven track record in educational institutions, hobbyist projects, and commercial automation systems demonstrates its versatility across diverse applications from simple LED controllers to complex sensor data acquisition systems.
Frequently Asked Questions
Can the BS1-IC be reprogrammed multiple times?
Yes, the BS1-IC features EEPROM program memory that supports unlimited erase-write cycles for practical purposes. You can reprogram the module thousands of times during development and testing without degradation. Each programming cycle takes approximately 10-15 seconds through the serial interface using the BASIC Stamp Editor software.
What is the maximum frequency I can toggle an output pin?
The BS1-IC can toggle output pins at approximately 1 kHz maximum frequency when executing PBASIC commands. For applications requiring higher frequency outputs such as PWM signals above 1 kHz, you would need to implement the timing logic using external hardware circuits or upgrade to the BS2 module which offers faster instruction execution.
How do I interface analog sensors to the BS1-IC?
The BS1-IC does not include an integrated analog-to-digital converter. To read analog sensors, you must use an external ADC module such as the Parallax ADC0831 or ADC0834, which communicates with the BS1-IC through serial or parallel protocols. Alternatively, you can implement a simple RC timing circuit with a capacitor and measure the charge-discharge time using the module's digital inputs to approximate analog values.
