Download the HMI project file here

What you will need?
1.Nextion display*1

2016 Chinese Spring Festival Holiday Schedule

The 2016 Chinese Spring Festival is coming soon, and we will have a 12-day holiday then. Here, we would like to release the order processing schedule in advance so that you can place your orders ahead of time.
From Feb.1st to Feb.15th,2016, almost everything will be 10% OFF*. In view cart, you will get 10% off grand total automatically. This promotion is applicable with other promotions/discounts/offers.

For PCB/FPC orders received from January 24th to February 2nd, we will arrange for production, yet we cannot guarantee delivery before the holiday due to the production cycle. Although the holiday has not yet started, workers in many factories in China have begun to ask for leaves to prepare for the Spring Festival, thus many factories started to reject new orders because of production capacity, which means that the production cycle of PCB/FPC boards will be extended to 5-8days from 3-4 days originally. 

From February 3rd to February 14th, we will have a 12-day Spring Festival holiday, and we will be unable to process your orders and shipments then. Besides, production of PCB orders will be stopped. During this period, our staff will be at home, and there may no access to the Internet and e-mails. Therefore, your e-mails may not be handled on time. We apologize for any inconvenience this may cause.

We will be back to work on February 15th. Because of the backlog of orders and e-mails during the holiday, they may be processed a bit slowly than usual, and we will try to get back on track as soon as possible. Thank you for your understanding and support.

How to Make W5100 Module Work with SD Card Module?

Some people may find out our W5100 module can`t work with SD card module at the same time, you can`t read/write any data from/to SD card.

Here is an solution for that. According to the schematic of our W5100 module, the SEN pin is always pulled up by 10K resistor.

That means the SPI of W5100 has always been enabled. So it might affect the communication between the MCU and the other SPI device.

Now you can solder the SEN pin to the CS pin of SD card slot. And set the CS pin of SD card socket to high voltage before you communicate with W5100 module. It will fix this problem.

Nextion Gradient Progress Bar Project

This post I`m going to teach you to build a gradient progress bar project. Gradient progress bar has been widely applied to many places like refresh page, buffer zone. For HMI designing, I think it is a very important and practical project.
Download the HMI project file from here.

I`m going to build a project containing 3 kinds of Old Sankey like progress bar, and make them switchable. We all know that there is a progress bar component available in the software, but that is only single bar, which is not helpful because what I need is gradient progress bar that combined with many bars.
