BASIC Stamp® 2e Module Firmware Revision Details
This document contains details of revisions made to the BASIC Stamp 2e module firmware. In many
cases, newer firmware simply provides minor enhancements and older firmware will not adversely
affect your application. Please check the notes below to determine if your application could benefit
from the indicated firmware modifications.
You can check the firmware version of your BASIC Stamp 2e module by connecting it to your PC and
selecting the Identify function in the BASIC Stamp Editor.
Firmware Revision: v1.2 Date Released: 07/2007
Required Software: BASIC Stamp Windows Editor v2.3.1 (or higher)
Items Modified Notes
Adjusted firmware to disable internal brown-out detector (inside the
interpreter) to instead use an external brown-out detector (outside the
interpreter, but included on the module). This firmware change is in
coordination with the design of the BS2e Rev E module (which includes
the additional brown-out detector on-board) in order to support the
industrial temperature range specification.
Affects very few
applications since only
older modules in extreme
temperatures (around
-40C or +85C) are
subject to problems.
Firmware Revision: v1.1 Date Released: 05/2004
Required Software: BASIC Stamp Windows Editor v2.1 (or higher)
Items Modified Notes
Fixed firmware error that caused GET and PUT commands to
mishandle address values higher than 62. Address 63 should have been
ignored for the PUT command. Addresses 64 and higher should have
wrapped around to address 0 and higher. The error caused SPRAM in
addresses 32 and higher to be modified if the PUT command was given
an address of 63 or higher.
Affects very few
applications since the
only valid SPRAM
locations are 0 through
63; most programs are
written to stay within that
range.
