本篇帶給大家HiSpark Wi-Fi IoT智能小車套件上手之燒錄出廠樣例，希望對你有所幫助！

1.下載樣例代碼

①.gitee倉庫地址

https://gitee.com/hihope_iot/hispark-pegasus-smart-car.git

②.克隆代碼到本地

git clone https://gitee.com/hihope_iot/hispark-pegasus-smart-car.git

③.將樣例代碼拷貝到openharmony

目錄：hispark-pegasus-smart-car\智能循跡避障小車樣例代碼\robot_demo 
拷貝到：openharmony\applications\sample\wifi-iot\app\

2.使能編譯IIC驅動

目錄：openharmony\device\hisilicon\hispark_pegasus\sdk_liteos\build\config\usr_config.mk。

找到這里
# CONFIG_FACTORY_TEST_SUPPORT is not set
# end of Factory Test Settings
#
# BSP Settings
#
CONFIG_I2C_SUPPORT=y        《《《打開編譯IIC驅動，改成這樣
# CONFIG_I2S_SUPPORT is not set
# CONFIG_SPI_SUPPORT is not set
# CONFIG_DMA_SUPPORT is not set
# CONFIG_SDIO_SUPPORT is not set
# CONFIG_SPI_DMA_SUPPORT is not set
# CONFIG_UART_DMA_SUPPORT is not set
CONFIG_PWM_SUPPORT=y
CONFIG_PWM_HOLD_AFTER_REBOOT=y
CONFIG_AT_SUPPORT=y
CONFIG_FILE_SYSTEM_SUPPORT=y
CONFIG_UART0_SUPPORT=y
CONFIG_UART1_SUPPORT=y
# CONFIG_UART2_SUPPORT is not set
# end of BSP Settings

3.把樣例加入編譯

目錄：openharmony3\applications\sample\wifi-iot\app\BUILD.gn。

import("http://build/lite/config/component/lite_component.gni")
lite_component("app") {
    features = [
        "robot_demo:robot_demo",
        "robot_demo/ssd1306:oled_ssd1306",
    ]
}

注意：官方樣例使用說明 https://gitee.com/hihope_iot/hispark-pegasus-smart-car 里面的 BUILD.gn 未將 oled_ssd1306 加入編譯，不加入會報錯。

4.編譯樣例

①.設置編譯路徑

hb set
.(英文字符)

復制②.選擇wifiiot_hispark_pegasus

③.執行編譯

hb build -f

5.燒錄

①打開HiBurn燒錄工具

②. 選擇要燒錄的文件

點擊select fine
選擇該路徑：openharmony\out\hispark_pegasus\wifiiot_hispark_pegasus 下的Hi3861_loader_signed.bin和Hi3861_wifiiot_app_allinone.bin

復制

③.勾選上 Auto burn

④.燒錄

點擊Connect

⑤.開發板復位

開始燒錄。

⑥.燒錄完成，點擊disconnect按鈕

6.測試結果

測試成功!

7.報錯解決

①.未使能驅動編譯

報錯提示：

[OHOS ERROR] riscv32-unknown-elf-ld: ohos/libs/libhal_iothardware.a(libhal_iothardware.hal_iot_i2c.o): in function `IoTI2cInit':
[OHOS ERROR] hal_iot_i2c.c:(.text.IoTI2cInit+0x10): undefined reference to `hi_i2c_init'
