Time to update an old friend
20 years ago I was doing some process control for a new type of
display. Our physicist wanted to set up some burn in and aging
tests. I had been using an 68HC11 as my tool of choice on a board I
designed with a lot of prototype area on it. I suggested he use that.
He said sure and asked what do you program it with. I said
"assenbly language". He looked at me like I had 2 heads or
something, he suggested we use something called a BASIC stamp from
Parallax. We did and it did a lot of the simple test tasks
was 20 years ago and while there are a lot of alternatives now, the
original form factor has a lot going for it. However that stamp
has not been updated in those 20 years.
- when was the last time you saw an RS-232 port on a PC?
- 32 bytes of memory in the original, shouldn't that be increased some amount of K?
- 2K of program space in the original, should grow by 50 times or more
- 5 volt tolerance is still important in 3.3V or lower world
- 16 bit words then, 32 now with arrays added.
- floating point and strings would be nice to have
- just BASIC?, how about C or C++ too
- of course speed is often an issue
its time to bring some modern components to that 24 pin form factor.
Take a 50 MHz 32 bit ARM with builtin USB and put it in that same
form factor. As there are more than 16 IO pins grow it in width
to get to those 40 pins, but KEEP the same stamp 24 pin footprint.
got here from a KickStarter campaign, the latest updates are there, but
when that is successful this page will go live and it will be a
product you can order. If you want a head start get in on the
