DEVELOPMENT HARDWARE & SOFTWARE
SMH4814
Preliminary Information
The end user can obtain the Summit SMX3200
programming system for device prototype
development. The SMX3200 system consists of a
programming Dongle, cable and Windows^TM GUI
software. It can be ordered on the website or from a
local representative. The latest revisions of all
software and an application brief describing the
SMX3200 is available from the website
(www.summitmicro.com).
The SMX3200 programming Dongle/cable interfaces
directly between a PC’s parallel port and the target
application. The device is then configured on-screen
via an intuitive graphical user interface employing
drop-down menus.
The Windows GUI software will generate the data and
send it in I²C serial bus format so that it can be directly
downloaded to the SMH4814 via the programming
Dongle and cable. An example of the connection
interface is shown in Figure 34.
When design prototyping is complete, the software
can generate a HEX data file that should be
transmitted to Summit for approval. Summit will then
assign a unique customer ID to the HEX code and
program production devices before the final electrical
test operations. This will ensure proper device
operation in the end application.
