Prompted by another thread I shought I would ask if anyone is using these
small controllers that run simple BASIC and are very easy to code and
program sing only an RS232 port - no programmer needed.
There are several in the rang of Kronos at http://www.kronosrobotics.com or
in UK http://www.hobbycontrol.co.uk/index.php
In the UK schools the 15 yr olds learn programming with the Picaxe
http://www.rev-ed.co.uk/picaxe/ range which seem to have a special very
small (cheap) one for education. These devices have an advantage over the
Kronos ones in having an interupt available.
Both have free simulators that are great - I have spent hours trying things
out without any cost.
For anyone afraid of programming a micro like a PIC these are the thing:
1/ do not need a programmer - they are programmed directly through the RS232
2/ they have an RS232 interface so very mh friendly
3/ they are programmed in BASIC which you can learn in 5 minutes
4/ they can be reprogrammed in seconds so you can re use them for something
5/ they cost peanuts (actually about 1/3 the cost of a 555 timer 25 years
6/ free simulator
7/ very similar to Weeder boards but more versatile
So far, while I wait for my Kronos Athenas to arrive, I have simulated a 64
input 24 output line interface with one Athena plus some latches using a 3
byte addressing system that goes like 'Address', 'port', 'Set/Reset',
carriage return. eg A1S<cr> which is very like a Weeder interface. That has
got to be enough i/o for most houses but if not they can be daisy chained.
I have also simulated an 8 output DtoA to drive Velleman lamp dimmers but
this may need a Picaxe for the interupt feature.
