1. Unboxing Contents:

• AiPi-R2 development board ×1
• Camera module: Coovision CV031C50 ×1
• 4-inch touch display: Uye UE040WV ×1
• 65dB microphone ×1
• 8Ω2W speakers ×2
• Connection cables ×2

Issue: Internal packaging is very detailed, but the outer carton is too soft, risking hardware damage.

2. Environment Setup

Using VScode for compilation. Refer to: “Beginner Guide: Setting up AiPi-R2 Windows Environment” on Ai-Thinker Forum.

Encountered issue during compilation:

Fix: Open aithinker_Ai-M6X_SDK\project.build, comment out lines 75 and 76 by adding # at the beginning and save.

#        cp $(BL_SDK_BASE)/bsp/board/bl616dk/config/edata.bin build/build_out 

#        cp $(BL_SDK_BASE)/bsp/board/bl616dk/config/Rx_boot2_m61.bin build/build_out 

3. Example Testing

No onboard LED (recommended to add one), making it hard to verify board operation without a display.

LVGL Demo: Reflashed official LVGL example using make for compilation and make flash COMX=COM3 for flashing (COM3 is USB-TTL port).

Re-burn the LVGL official routines. Use make to compile the code and make flash COMX=COM3 to burn it. COM3 is the port currently connected to the development board. Use USB to TTL. The connection diagram is as follows:

4. LVGL Integration & Testing

LVGL was customized based on the AiPi-Eyes-Rx example. After GUI design using GuiGuider, generate and replace the generated folder under demos\ai_lvgl\src\generated.

5. SPI TF Card Reading & FATFS Filesystem

Wired the onboard SPI to a TF card module (or solder a TF slot). Adjust pin definitions accordingly.

Key SPI code: Refer to

aithinker_Ai-M6X_SDK\examples\peripherals\spi\spi_poll，SPI configuration and TF card initialization code included in the document.

void spi_isr(int irq, void *arg)

{

    uint32_t intstatus = bflb_spi_get_intstatus(spi0);

    if (intstatus & SPI_INTSTS_TC) {

        bflb_spi_int_clear(spi0, SPI_INTCLR_TC);

        //printf("tc done\r\n");

        spi_tc_done_count++;

    }

    if (intstatus & SPI_INTSTS_TX_FIFO) {

        //printf("tx fifo\r\n");

    }

    if (intstatus & SPI_INTSTS_RX_FIFO) {

        //printf("rx fifo\r\n");

    }

}


void SPI_init(u32 freqm)

{

    struct bflb_spi_config_s spi_cfg =

    {

#if (SPI_CASE_SELECT == SPI_MASTER_CASE)

        .freq = freqm,

        .role = SPI_ROLE_MASTER,

#else

        .freq = 32 * 1000 * 1000,

        .role = SPI_ROLE_SLAVE,

#endif

        .mode = SPI_MODE3,

        .data_width = SPI_DATA_WIDTH_8BIT,

        .bit_order = SPI_BIT_MSB,

        .byte_order = SPI_BYTE_LSB,

        .tx_fifo_threshold = 0,

        .rx_fifo_threshold = 0,

    };

    spi0 = bflb_device_get_by_name("spi0");

    bflb_spi_init(spi0, &spi_cfg);

    bflb_spi_tcint_mask(spi0, false);

    bflb_irq_attach(spi0->irq_num, spi_isr, NULL);

    bflb_irq_enable(spi0->irq_num);

    bflb_spi_feature_control(spi0, SPI_CMD_SET_CS_INTERVAL, 0);


}

// Modify board.h and add the following:

void board_spi0_gpio_init()

{

    struct bflb_device_s* gpio;

 

    gpio = bflb_device_get_by_name("gpio");

    // spi cs

    bflb_gpio_init(gpio,...
