SMH4814
Preliminary Information
DEVELOPMENT HARDWARE & SOFTWARE
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.
