[Fudan Micro FM33LG0 Series Development Board Review] Unboxing + Great Lighting + HELLO WORLD! [Copy link]

 

Received the review board today, so excited!!

First picture:

The workmanship of the board is still OK!

2. Power on

With an excited heart and shaking hands, I plugged in the ST-LINK2:

ST-LINK Development Board

SWD SWIO

GND GND

SLC SWLCK

VCC VCC

Plug it into the USB port of the computer , and the four LEDs flashed and sparkled, making my eyes dazzled :), and the startup was finally successful!

Open Kiel, fortunately the board recognizes this CPU:

Click the download button to download successfully:

The LED3 of the development board starts flashing quickly, and then flashes once per second after a while. Yesterday, I saw a group friend say that Jlink cannot be recognized, and I bought two DAP-LINKs, wasting dozens of dollars.

In addition to the lighting method, there is also the hello world! routine that initializes UART0. The routine is: DebugUartInit. Checking the schematic diagram, the UART0 socket is J8. I looked for it for a long time but couldn't find it. Later, I saw that the silk screen of J8 was not very clear. Looking directly at the schematic diagram of the board, TX is PA14 and RX is PA13 (this is a bit opposite to STM32. STM32 usually has TX in front and RX in the back. Do you feel that the icons of Mac OS and Windows are also opposite? Hehe!). Add printf("HELLO WORD!\r\n") in the main program.

#include "main.h"
#include "user_init.h"

int main(void)
{
    /* Reset of all peripherals, Initializes the Flash interface and the Systick. */
    /* SHOULD BE KEPT!!! */
    MF_Clock_Init();

    /* Configure the system clock */
    /* SHOULD BE KEPT!!! */
    MF_SystemClock_Config();

    /* Initialize FL Driver Library */
    /* SHOULD BE KEPT!!! */
    FL_Init();

    /* Initialize all configured peripherals */
    /* SHOULD BE KEPT!!! */
    MF_Config_Init();

    UserInit();

    while(1)
    {
        LED0_TOG();
		printf("Hello World!\r\n");
        FL_DelayMs(1000);
    }
}

Open the serial port assistant and hello world! is printed out.

Well, in general, unpacking and downloading the program went smoothly. If you have experience in STM32 development, it is very easy to get started with this development board. This unpacking ends here, let us look forward to the subsequent evaluation!

Amazing, st-link actually supports

They are all standard SWD interfaces. If the compatible protocol is good, common simulation and debugging software can be used.

Boss, can I use xcom? My xcom has not responded

It should be OK. Use an oscilloscope to see if the data comes out.
