Users of the ATMEL range of RISC-based microcontrollers can access local documentation but see also the main ATMEL
page at http://www.atmel.com for the
absolutely most recent material.
Users of the Dallas Semiconductor (now merged with MAXIM) small java
based microcontroller device called TINI will know about www.ibutton.com as a source of
information (tools, resources, purchase). You may need to sign an
agreement specifically allowing the developer to change the product format
(I signed in 1999, they changed pin count in 2000!). A product that used
both the TINI and some ATMEL devices is my printer
development work.
Users of the 68HC11 can access an assortment of 68HC11F1 resources, including manuals and software.
My assembly language programming manual for the 68HC11 is in ZIP archive http://mirriwinni.it.jcu.edu.au/~ftp/uP/68HC11.local/6811ref.zip
(it covers use of the assembler plus a few other topics).
If you use micro-controllers and micro-processors, check out http://mirriwinni.it.jcu.edu.au/~ftp/uP
where a variety of cross assemblers and other tools for various 8 bit
devices is kept.
The 68HC11F1 board by Pete Dunster (University of Wollongong) has
software and hardware design material available at http://mirriwinni.it.jcu.edu.au/~ftp/UoW.
Software, software tools, and construction details for Pete Dunster's
68HC11F1 board (prepared by me) are available from here.
Users of TI TMS320C6211 and Motorola 56300 family DSP devices may
find DSP tool hints of use. The use of WINE
to support non-unix tools on (BSD) unix is also described.
Also see my DSP
information for other support tools.
