【Fudan Micro FM33LC046N Review】+ LED and KEY [Copy link]

 

As the year draws to a close, problems have arisen one after another, disrupting the original schedule...Stay strong...

I used LED and key briefly, and will continue...

The DEMO comes with four LED lights. Calling library functions to light up the LEDs uses a library similar to ST.

in:

LED1----->PC0

LED2----->PC1

LED3----->PB10 (J42 jumper short-circuit)

LED4----->PB9 (J43 jumper short-circuit)

First, simply use the key to call IO to light up the LED light

Some personal feelings:

1. I feel that FM should be building its own library functions and related library function manuals, so that it will be easier for users to get started. I look forward to the early release of the manual;

2. For the next demo, you can consider replacing the 5V power supply port with a commonly used USB port. It will be more convenient to power it. You can leave it unwelded like now, and you can add it yourself later .

3. The board is very good, to be continued...

Please advise!!!

Why after I burned your program, the four small lights on the development board kept on and the buttons didn't work?

Check if there is any problem with the IO driver function configuration. Only KEY1 and KEY4 are used.

The following link contains some engineering codes for peripherals, which you can refer to:

I still don’t understand. Why don’t you add my QQ (QQ:1269909129) and I will ask you for detailed advice. Thank you, brother!
