mainboard
The mainboard includes a programming and
data streaming header as also illustrated in the
figure.
The EV-Kit is interfaced to a personal
computer for data streaming and programming
OTP options, by means of the Azoteq
Configuration
Tool
(CTxxx).For
IC
programming and visual data streaming please
utilize
the IQS232 GUI, IQS243 GUI and
USBProg software, provided on the Azoteq
website. (www.azoteq.com).
