Still in connection. Please power on MCU...

Stc12c2052 download the program.

In this regard, I was a cainiao. I read du Yang's book and ran to Xi Si, and switched the electronic market again. I didn't find stc12c2052, A boss suggested that I buy a 51 series of 89C2051, saying that the functions should be similar. The shopkeeper pushed me out of his pocket and went back to the Internet to check it. Then I ran to Zhongguancun and bought stc12c2052 on the first floor. Then I bought a USB-to-serial cable for 12 yuan.

Go home and follow the steps in Du yangshu, the battery box and the bread board are connected, and the light finally lights up! Haha, very excited.

Next we should learn to download the program. I ran more than 80 miles, and I went to the octal line and Line 10 to buy a USB-to-Serial Line. The figure was cheap and I spent 12 yuan. The boss is better, this line may not be easy to use. If not, it will be returned. The boss's shop was the first stall on the back of the stairs on the ground floor.

If the program cannot be downloaded, a report is reported."The connection is still in progress. Please power on the MCU...",Then there were 10 more prompts about check errors. I followed them one by one, but the results were not satisfactory. Later I ran to Zhongguancun, and the seller's boss withdrew the goods. The boss was so nice, let me try again.

I don't know where the error occurred, so I decided to follow the USB to UART module used in the next chapter of DU yangshu (making download lines, I felt that was okay. Then I tried to find a stall at the booth. I ressed it and couldn't find it! No one has done such a simple thing. I'm a little disappointed. How can this problem be solved? I guess it is also the national boss ). I saw a lot of learning boards in a shop selling development boards, and many things on the books are quite similar to those on DU daoda (my kind of respect for du Yang, then I asked the boss if he had the USB-to-UART module. The boss was a pretty girl and looked white in her twenties. The boss hasn't answered yet. It is estimated that the man next to him is her boyfriend and said, "No, I haven't found it in the electronic city of China! A lot of people have come to us, but they haven't .". I thought it would be over, but the program could not be downloaded and I still learned a fart! But what I'm not sure about is what caused the download to fail? Is the USB-to-serial port line, the bread board, the circuit connection error, or the capacitor problem, even the circuit problem of the bread is not certain, or it is because I bought a bad maxcompute. Stc12c2052 must be correct, because the experiment light is on.

I decided to change the USB-to-serial line first. This time I bought a pair that can be used, and then I bought a few more capacitors. boss Du said that the capacitor should be written in 104 words. I bought a pair Z before, I checked it online and said no problem. Then I bought another maxcompute instance. In this way, we will try again.

Asked the beauty boss, their USB-to-serial line is also the type of green outer skin 12 yuan line, but she is sure to use it, and do not return the goods, it seems that this is the case where the beauty is ah, not generous. I ran to another store and bought a capacitor, maxcompute. I bought a USB-to-serial cable without wires at 38, but I still feel a little distressed. After all, I am playing.

Make a long journey to your home. Before the breath is exhausted, all of these are switched to the bread. Connect to the computer, open the software, select the program, click Download, and then turn on the MCU battery box power, wait...

When a warning is reported,"Still in connection. Please power on MCU... ",I'm so stupid!

After a long time, I checked the software and found that I had been ignoring the single-chip microcomputer Model! Because he has been reading boss Du's book for the past few days, the name of stc12c2052 is always in front of him, so he is familiar with it, but now how this model is so awkward, take a closer look, what's 2052? It turns out to be 5202! It turned out that I was careless at the beginning, thinking that the STC single-chip microcomputer only has such a model, so I did not look carefully. I found 2052 again, click to download it, And the MCU was powered on. I saw a PC handshake, and then the MCU finally responded. The screen jumped and a bunch of text, dog or something, then a scroll bar is rolled over. Then the led from the single-chip computer starts to flash quickly! Successful! Now my heart has no such impulse to jump up, maybe it's too long to wait, too much disappointment, and my heart has been flattened. It seems that learning single chip microcomputer can make people feel humiliated! It's really a success.

I can finally download the program. No matter how far I can go, but the previous learning experience shows a problem, no matter how stupid, how silly people can learn SCM. Of course, I 'd like to thank Mr. Du for not having any guidance. I still don't know how to learn it!
