I hit a wall when I used EasyEDA for the first time [Copy link]

 

 

Today I am drawing PCB with reference to Sipeed's Tang Nano 9k, because I find EasyEDA more convenient recently. I have used it to export some packages to AD before, and it is suitable for lazy people like me. The board this time is not very complicated, so I want to practice with EasyEDA. I downloaded EasyEDA for offline board, created a new project, put the main chip of gw1nr-lv9qn88p, and then found that it does not match the schematic diagram of Tang Nano 9k when drawing the clock input.

The external clock of tang nano 9k is connected to pin 52, which corresponds to GCLKT_3, but the one in LiChuang EDA is GCLKC_3, which is one pin different.

After careful comparison, I found that pin 47 is correct, both are IOB43B. Pin 48 and above should actually be IOR24B, which is IOR5A in EasyEDA. According to the GW1NR-9 device Pinout manual, IOR5A should correspond to pin 63.

Basically everything is wrong starting from pin 48. The weird thing is that this is not the kind of error where all networks go back one pin. Pin 58 in EasyEDA is VCCO2, but it is actually VCCO1. There seems to be no pattern.

I have considered using some free tools before. I installed KiCad before, but I gave up because I was not used to the operation and had no motivation to learn. This time I used EasyEDA because I could directly use the online PCB library and save the steps of drawing package verification. I wanted to give it a try. I didn’t expect that within 20 minutes after installing the software,…

However, it is normal to make mistakes in package drawing. I also encountered errors in the BXL file downloaded from TI. I remember the email I received after I gave feedback to TI saying that they would not bear any responsibility for the package provided, although I only told them that the package was drawn incorrectly and this wrong package had not been modified for a long time.

This time I tried to right-click on the package and found an option to report an error, which is very good. After clicking it, a window pops up to enter the error information and submit it. I have already reported this issue to EasyEDA and will see what kind of response they will get.

No matter what, I think EasyEDA is a very good tool. The one-stop service of design-proofing-steel mesh-parts purchase-chip placement is very convenient and economical. Finally, I hope that domestic EDA software will get better and better.

This EDA is very convenient. It is very convenient to draw a small picture online. The regular component library is also available.

You really need to be careful when using this chip.

Some of its libraries are shared by netizens and are not necessarily provided by the official device.

Yes, I think EasyEDA is still very promising. Online PCB libraries like this are very convenient for small companies and individuals. I am also very lucky that I found this error just after placing two components. If I can't adjust it after soldering it, I will be screwed.

EasyEDA is good for drawing a simple board, but its complex functions are not easy to use yet, and the rule settings are a bit simple.

In terms of packaging, LiChuang’s own packaging is better, and third-party packaging requires special care.

Report it to the official website and ask them to modify the library files, which is also a good thing.

I coveted the LCEDA file milling sample discount, but I will have to pay it back sooner or later, haha

There are so many pins, so you still have to check carefully.

I used a lot of packages last time, all of which had fewer pins.

I am going to use EDA to draw a board recently. I will tell you about my experience then.

How to distinguish between your own and those of third parties?

Are there any discounts for LCEDA milling samples?

I guess my situation is not very common. I just started using it and I think I will have a lot of problems if I play with it for a few days.

OK, waiting for your sharing

I used their EDA drawing board and milled PCB samples for 3 yuan including shipping for 10 pieces, while other EDA tools cost 20 yuan. However, their files cannot be imported into other EDA tools. Once you enter, you cannot get out. If you are not afraid of being screwed in the future, save this money.

Can't it be exported to other tools? I tried AD and it works. This is how the previous packaging was done.

When adding components, those with a check mark in front (usually components from the mall) are generally verified.

Those that are not checked are usually added by other users and need to be checked and confirmed by yourself.

I was wrong about that, I just heard too many complaints

The author is very careful, and found this small mistake.

I have used LCEDA many times and I feel it is very convenient and affordable. I have not found any major problems with the products I have made.

It may also be that our products are too simple and microcontrollers are rarely used.

Next time I encounter a device with many pins, I will refer to your method and check it carefully.

What software do you usually use to draw boards?
