macbs2

Important Note

MacBS2 will not run on Mac OS X 10.7 (Lion).

MacBS2 uses a software library provided by Parallax to compile your source code to something a BS2 chip can run. This library (called the 'Tokenizer' by Parallax) is available as a PowerPC library only, so linking to it requires the application (MacBS2) to be PowerPC as well.

There is no PowerPC support on Lion, and Parallax have not upgraded their library since 2004. So we are out of luck for the time being.

If you'd like to see a MacBS2 that runs on Mac OSX 10.7 (Lion), give Parallax a shout through their support page and let them know that a native library for Intel based Macs is important to you. Once an upgraded library is available, I can do the rest.

I got tired of having to run Virtual PC to program Stamp chips, and Parallax finally released a PBasic tokenizer library for the Mac. So I wrote a Stamp programming app for Mac OS X. It works. And you can use it with either the DB9 equipped Keyspan serial adapters (USA19, USA19x, etc.) or the Keyspan with the two small round connectors (USA28, USA28x, etc.). It also works with FTDI chip based adapters and Parallax' USB Board of Education (but see this FAQ).

system requirements

Parallax BS2, BS2e, BS2p, BS2p40, BS2pe, or BS2sx Basic Stamp chip
Mac OS X 10.4 (Tiger) through Max OS X 10.6 (Snow Leopard)
If you're using an RS-232 based board, the Keyspan USB to Serial adapters (either the USA-19 family or the USA-28 family) have been tested and are known to work. You'll need version 1.4 or newer of the Keyspan driver (works with both adapters, download it here)

Here is a table of other serial adapters I have tried.
If you're using Parallax' new USB Board of Education, or an FTDI based USB-Serial adapter, see this FAQ
