调试记录2

使用硬件SPI

上次的模拟SPI速度有些感人，这次使用硬件SPI

csi_gpio_pin_t pin_clk;
csi_gpio_pin_t pin_mosi;
csi_gpio_pin_t pin_cs;
csi_gpio_pin_t pin_miso;

static void oled_pinmux_init()
{
    csi_pin_set_mux(PA28, PA28_SPI1_SCK); //clk
    csi_pin_set_mux(PA29, PA29_SPI1_MOSI); //mosi
    csi_pin_set_mux(PA27, PIN_FUNC_GPIO); //cs
    csi_pin_set_mux(PA30, PIN_FUNC_GPIO); //miso
}

static void oled_gpio_init()
{
    csi_gpio_pin_init(&pin_cs, PA27);
    csi_gpio_pin_dir(&pin_cs, GPIO_DIRECTION_OUTPUT);
    csi_gpio_pin_init(&pin_miso, PA30); //dc
    csi_gpio_pin_dir(&pin_miso, GPIO_DIRECTION_OUTPUT);	
	
	int32_t ret = csi_spi_init(&spi_handle, 1);
    if (ret < 0) {
        printf("csi spi init failed\r\n");
        return NULL;
    }

    csi_spi_mode(&spi_handle, SPI_MASTER);
    ret = csi_spi_baud(&spi_handle, 20000000);
    
    csi_spi_cp_format(&spi_handle, SPI_FORMAT_CPOL0_CPHA0);
    csi_spi_frame_len(&spi_handle, SPI_FRAME_LEN_8);
    csi_spi_select_slave(&spi_handle, 1);
#ifdef SPI_USE_DMA
    csi_spi_attach_callback(&spi_handle, spi_event_cb, NULL);
    csi_spi_link_dma(&spi_handle, NULL, &spi_recv_dma);
#endif

}

 

移植uGUI

μGUI - free Open Source GUI module for embedded systems | Embedded Lightning

µGUI is a free and open source graphic library for embedded systems. It is platform-independent and can be easily ported to almost any microcontroller system. As long as the display is capable of showing graphics, µGUI is not restricted to a certain display technology. Therefore, display technologies such as LCD, TFT, E-Paper, LED or OLED are supported. The whole module consists of two files: ugui.c and ugui.h.

需要提供以下驱动，主要是画点函数

UG_GUI gui;
​
static UG_RESULT HW_FillFrame ( UG_S16 x1, UG_S16 y1, UG_S16 x2, UG_S16 y2, UG_COLOR c)
{
    LCD_Fill(x1,y1,x2,y2,c); 
    return UG_RESULT_OK; 
}
​
static UG_RESULT HW_DrawLine ( UG_S16 x1, UG_S16 y1, UG_S16 x2, UG_S16 y2, UG_COLOR c)
{ 
    return UG_RESULT_OK;
}
 
static void pset(UG_S16 x,UG_S16 y,UG_COLOR c)
{
    LCD_DrawPoint(x,y,c);
}
​
void gui_ugui_init()
{
    
    oled_hard_init();
    
    UG_Init(&gui, pset, 160 , 80 ) ; 
//  UG_DriverRegister( DRIVER_DRAW_LINE,  HW_DrawLine ) ;
    UG_DriverRegister( DRIVER_FILL_FRAME,  HW_FillFrame ) ;
    
//  UG_DriverEnable ( DRIVER_DRAW_LINE ) ;
    UG_DriverEnable ( DRIVER_FILL_FRAME ) ;
}

这样就可以直接调用其丰富的绘图函数了

这是外接了一个彩屏了吧？

是的
