1. GPIO project code analysis

No matter east, west, south or north, everything can be turned into a light bulb, so let’s start with GPIO. However, the code is really simple and clear.

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

int main(void)
{
    MF_Clock_Init();
    MF_SystemClock_Config();

    FL_Init();

    MF_Config_Init();

    UserInit();

    while(1)
    {
        LED0_TOG();
        FL_DelayMs(5000);
    }
}

Initialization includes clock, board, configuration and user customization, and then it is a loop.

LED0_TOG();
FL_DelayMs(5000);

The problem is that there is no API code guide. How can we solve this problem? In fact, it still comes from the manufacturer's definition document.

#define LED0_TOG() FL_GPIO_ToggleOutputPin(LED0_GPIO, LED0_PIN)

The files are all from the following

#include "fm33lg0xx_fl.h"

2. Compilation of the project

Click Compile to start compiling directly and pass smoothly.

3. Code Download

If the blank chip is not soldered on this board, it should be a bare board with all the pins connected, and you need to bring your own debugger to download it.

After testing, the following models of debuggers are all available, one is jlink7.0, the other is jlink8.0. It seems that the chip does not have a verification and locking process. Among them, the jlink OB model is a public version limited to manufacturers, and it works well.

When using SW download, only two SWO and SCK are needed, which are for data and clock respectively, as shown below. When downloading, a reset key is also required. During the download process, this problem is prompted, but the download is successful without pressing reset.

The console output is as follows,

Follow the instructions above. If the downloader does not have a dedicated download button, just press reset.

The original delay was 1 second, 1000ms. Changing it to 200ms flash mode went relatively smoothly, but it was a bit too flashy.

Complaint: I recently received a call from Digital China as an agent. I still think it is strange that domestic chips choose such an American company as an agent. Lenovo can make the company lose money and then go public on the Science and Technology Innovation Board. At the same time, the annual salary of executives is over 100 million, which is much higher than that of the boss Li Shufu. Instead of this, I prefer to use TI products. If I want to choose an agent, I will go to Arrow.

Are you sure this jlink7.0 and jlink8.0 can be used?

This is good, good download compatibility

I didn't expect it to be usable. It's an antique from 2012.
