Re: OT w/ Disclaimer: Hobby Microcontrollers
- I use AVR's. The attiny2313, in particular, as it includes a UART,
enough flash and I/O to handle most of what I need to do. I did have
one project where I needed more I/O pins, but I simply split the
project into two logical parts and connected the UARTs together in
order to link the two parts. I could have easily gone to an AVR with
more pins, but will be able to reuse one half of this project in the
future. A serial interface is also handy to have available, if you
need to send or receive data from a PC.
The AVR instruction set, is easier to use, in my opinion, than the
PICs and 8051s. Compiled C code will often not fit in a micro-
controller's limited flash space, depending upon your application, so
this is an important consideration. Atmel provides both in-circuit
debugger capabilities and a simulator. Atmel's in-circuit debugger
costs around $300. The simulator has allowed for me to debug most
everything I've done, so I never purchased the interface for in-
circuit debugging. The AVR software tools are free, so the cost of
startup has been a flash programmer for around $29.00 and some AVR
chips. The interface from the chip to the flash programmer is simple
enough to slap together on a breadboard in a few minutes. There are
plans on the web for building your own flash programmer, but I think
that it is hardly worth the trouble.
