3 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.
There are Keil version and IAR version of all projects. Keil version of the projects are
created based on Keil MDK-ARM 5.25 uVision5. IAR version of the projects are created
based on IAR Embedded Workbench for ARM 8.31.1. During use, the following points
should be noted:
1. If you use Keil uVision5 to open the project. In order to solve the "Device Missing (s)"
problem, you can install GigaDevice.GD32E230_DFP.1.0.0.pack.
2. If you use IAR to open the project, install IAR_GD32E230_ADDON_1.0.0.exe to load
the associated files.
