[RVB2601 Creative Application Development] Bring up the development board and light up the LED [Copy link]

 

1. After unboxing last week, the development board was brought up this week. I encountered some problems and would like to share them with you.

2. Actually, before I received the board, I had already downloaded the CDK software and CH2601_SDK examples. As soon as I got the board, I ran through the helloworld example. At that time, I was wondering how it went so smoothly, because many people in the discussion group encountered various CDK bugs.

3. CDK I use Jianchi CDK integrated development environment V2.12.1. The CP210X serial port driver is already available on the computer, so the configuration of the development environment is very smooth.

After CDK is installed, open ch2601_rgb_marquee_demo.cdkproj directly. At this time, the Package is an exclamation mark. You need to download and update it, otherwise it will fail to compile.

However, after downloading the update, the Rebuild Project reported an error. I remembered that there was no problem with helloworld before. I verified the helloworld example and found a similar error. However, the error was still very obvious. It seemed that the path did not support spaces. I copied the entire project to the desktop and recompiled it and it was OK.

4. However, after downloading the Flash, I found that only the blue and green colors of the RGB LED marquee were lit, and the red color was not.

static uint32_t g_ctr = 0;
static csi_gpio_pin_t r;
static csi_gpio_pin_t g;
static csi_gpio_pin_t b;
void led_pinmux_init()
{
    csi_pin_set_mux(PA7, PIN_FUNC_GPIO);
    csi_pin_set_mux(PA25, PIN_FUNC_GPIO);
    csi_pin_set_mux(PA4, PIN_FUNC_GPIO);
    csi_gpio_pin_init(&r, PA7);
    csi_gpio_pin_dir(&r, GPIO_DIRECTION_OUTPUT);
    csi_gpio_pin_init(&g, PA25);
    csi_gpio_pin_dir(&g, GPIO_DIRECTION_OUTPUT);
    csi_gpio_pin_init(&b, PA4);
    csi_gpio_pin_dir(&b, GPIO_DIRECTION_OUTPUT);
    g_ctr = 0;
}

void led_refresh()
{
    g_ctr++;
    if (g_ctr % 3 == 0)
    {

        csi_gpio_pin_write(&r, GPIO_PIN_HIGH);
        csi_gpio_pin_write(&g, GPIO_PIN_LOW);
        csi_gpio_pin_write(&b, GPIO_PIN_LOW);
    }
    else if (g_ctr % 2 == 0)
    {
        csi_gpio_pin_write(&r, GPIO_PIN_LOW);
        csi_gpio_pin_write(&g, GPIO_PIN_HIGH);
        csi_gpio_pin_write(&b, GPIO_PIN_LOW);
    }
    else
    {
        csi_gpio_pin_write(&r, GPIO_PIN_LOW);
        csi_gpio_pin_write(&g, GPIO_PIN_LOW);
        csi_gpio_pin_write(&b, GPIO_PIN_HIGH);
    }
}

The code should be ok, so I checked if the hardware PA7 was not connected properly. I found that the default jumper cap was plugged in incorrectly. It seems that the default jumper cap configuration is also a pit.

5. After plugging in the jumper cap at the blue mark of RED (originally plugged under the jumper cap of BLUE), the demo effect is normal, see the attached video.

Yes, the path does not support spaces and cannot be compiled.

Others went well

I learned something, thank you!

There are still very few domestic RISC V chips. I still hope that there will be more and more domestic chips, the threshold will be lower, the use will be easier, and the performance will be stronger.
