[Preface] I haven't updated the post for a few days. One reason is that the work at the company is too heavy. After a busy day, I don't want to move. The other reason is that I am waiting for the wifi module of the screen to come back. Yesterday, I soldered the wifi module and several other components. Soldering 0603 was fine, but soldering 0403 capacitors took a long time, but the capacitors were not soldered. The reason is that my eyes are blurry due to old age. They run away when I blow them with an air gun, and I can't see them with a soldering station. It's a headache. So I want to buy a good set of equipment. I have to admit that I am old. But the wifi module still worked successfully, and it was successfully connected to the Devin Cloud to realize data interaction. Let me summarize it here today:

1. The screen I applied for supports wifi, but it does not come with a module by default. I went to the official Taobao of DWIN to buy a wifi module. The attentive lady told me that I needed several other components. So I contacted DWIN's salesperson and bought three modules (actually only two were needed, I kept one as a backup), and they also applied for three supporting components for me. Here is a comparison of the before and after:

After welding:

I am just an entry-level welder. It's a bit miserable...

2. Apply for an account on DWIN Cloud and create your own account and product:

After getting the manufacturer address, equipment classification address, and product number address, rewrite 22_config.bin

Note that the address in the bin file should be multiplied by the variable address by 2: that is, 0x822 \0x0826 0x828 The official website has a detailed tutorial, you can take a look if you need it.

Then, just configure the wifiSSD\password, it's very simple:

Let's show you, let's watch the video:

The next step is to realize the exchange of MQTT and background data.

[Summary] Programming is hard, but it’s also fun!

Aluminum electrolysis was replaced by SMD

The key to patch welding is whether the soldering iron is easy to use

I think that's an electrolytic capacitor. The manufacturer matched it like this. It's OK as long as it works. . .
