Getting started
The EVAL board uses Mini USB connecter to get power DC +5V, which is the hardware
system normal work voltage. A GD-Link on board is necessary in order to download and
debug programs. Select the correct boot mode and then power on, the LEDPWR will turn on,
which indicates that the power supply is OK.
The projects
are created based on eclipse 4.7.2. Note that to configure the “Debug
Configurations” before debug and download.
