}

注意：官方样例使用说明 https://gitee.com/hihope_iot/hispark-pegasus-smart-car 里面的 BUILD.gn 未将 oled_ssd1306 加入编译，不加入会报错。

hb set
.(英文字符)

复制②.选择wifiiot_hispark_pegasus

③.执行编译

hb build -f

点击select fine
选择该路径：openharmony\out\hispark_pegasus\wifiiot_hispark_pegasus 下的Hi3861_loader_signed.bin和Hi3861_wifiiot_app_allinone.bin

复制

点击Connect

开始烧录。

测试成功!
