安装依赖

已验证系统为：ubuntu 16.04.7 64位系统

sudo apt-get install subversion build-essential libncurses5-dev zlib1g-dev gawk git ccache \
		gettext libssl-dev xsltproc libxml-parser-perl \
		gengetopt default-jre-headless ocaml-nox sharutils textinfo
sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install zlib1g:i386 libstdc++6:i386 libc6:i386 libc6-dev-i386

安装toolchian

1. 下载toolchain 链接：https://pan.baidu.com/s/1SUk1a-drbWo1tkHQzCgchg 提取码：1o3d

2. 解压缩toolchain

sudo tar wt-gcc-arm-8.2-2018.08-x86_64-arm-linux-gnueabihf.tag.gz -xvf -C /opt/

2. 设置环境变量，修改 ~/.profile文件, 将下面这行添加到文件末尾

PATH="/opt/gcc-arm-8.2-2018.08-x86_64-arm-linux-gnueabihf/bin:$PATH"

手动生效环境变量

source ~/.profile

测试交叉工具链

arm-linux-gnueabihf-gcc --version

刷系统

如果系统为原始linux系统，请先通过如下方法将系统刷机成openwrt系统

上电按住Enter按键，进入uboot，执行如下命令（SSD202_openwrt.bin位于images目录下，请自行拷贝到tftp32服务器目录下，设置电脑IP为192.168.1.88）

setenv ipaddr 192.168.1.11
setenv serverip 192.168.1.88
tftp 0x21000000 SSD202_openwrt.bin
nand erase.chip
nand write.e 0x21000000 0x00 ${filesize}
reset

编译

make

库文件位于lib/liblvgl.so 可执行文件位于bin/demo

测试

将demo通过网口上传到板子（tftp或者scp），增加可执行权限，并运行。例如

cd /tmp
tftp -g 192.168.1.111 -r demo
chmod +x demo
./demo

如果板子没有liblvgl.so，可先手动上传。

cd /usr/lib/
tftp -g 192.168.1.111 -r liblvgl.so

Typo on the screen dropdown menu: "Tag page" instead of "Tab page"

Same typo in the documentation's screenshot.

While the documentation text reports rightly "Tabpage".

Read Gauge and Get Drop down "content" not connecting to set elements

Environment

I am using

• The online editor at 8ms.xyz
• IDO-SBC2D70 demoboard

Problem description

The "read gauge" and "get drop down" do not connect to the "set label " element content (see picture below).
The set element content works with "read label".

Expected behavior

The set label element connect flawlessly to both read gauge and get drop down.

Actual behavior

It only connect to read label.

Blockly setup

With read label the connection can be made, but not with the other two.
