I am looking at developing an industrial product which will have BT.
Obviously there are numerous ways to do it, with any microcontroller
and one of the BT modules.
My preference is towards the Atmel ATmega128 because we have some
other projects, currently using a Hitachi H8/323, which will
eventually be migrated to that. Atmel, along with Microchip, seems to
be the only company committed to a long term embedded business, with a
decent continuity of development tools.
But I wonder if anyone here has done it before and found some really
easy way.
Preferably the software should be written in C, maybe with a bit of
assembler for things like interrupt service routines (the product will
also have an RS485 port, 1200-115k baud) and we will need to write
some simple PC software to send out with it, for testing it.
I presume that the BT profile would be something like an FTP server -
it is for transferring values from an A-D converter.
Currently we use a TI A-D which is 12-bit, with an I2C interface, and
we do actually need the 12 bits (not 10 bits plus rubbish which is
usually the case with on-chip A-D converters).
I'd much appreciate any pointers to some low cost proven stuff which
is widely used.
