The BASIC® Stamp Logic Analyzer (BSLA) is a collaborative design between Parallax and CWAV, the developer of the popular USBee Pod logic analyzer series (http://www.usbee.com). The BSLA fits between a 24-pin BASIC Stamp and its programming socket.
The BSLA hardware connects directly to your PC’s USB 2.0 port. Download the documentation below to see pictures of the installed hardware. The software runs on your PC and displays the digital value of all BASIC Stamp I/O and programming pins.
BSLA Hardware Features:
- USB 2.0 High-Speed interface
- Power is from the USB port
- 2 Ms/s sample rates, fast enough for all Parallax 24-pin modules
- 20 channels (16 for I/Os and 4 for Vdd, Res, Sout, Sin)
- Thresholds set at 1.4V and 0.8V, supporting TTL and CMOS
- Small size (3.25 L x 1.95 W x 1.67 T cm / 1.28" L x 0.77" W x 0.66” T)
The BSLA software has the following features and may be downloaded below for evaluation:
- Compatible with Win2K/XP/VISTA operating systems
- Multiple triggering options on all channels
- I2C, asynchronous serial, SPI bus decoder
- Minimum sample depth of 1 million samples up to available PC RAM
- Sample clock generated internally
- Zoom in, zoom out and zoom all
- Save, Open and Print captured data and settings
- Movable cursors for easy measurements
Note: Your computer must have High Speed USB (USB 2.0) to use the BASIC Stamp Logic Analyzer. You can find out if your PC has USB 2.0 by looking in the Hardware Device Manager. Navigate Start Menu, Windows Control Panel, System, Hardware Tab, Device Manager, Universal Serial Bus section. If there is an entry for an "Enhanced Host Controller" then you have USB 2.0. If you don't have USB 2.0, you can purchase a USB 2.0 card for less than $20 at many online stores such as eBay.
