tft lcd quotes quotation

Leadtek has paid great efforts on research and development of TFT-LCM, especially on its application of consumable and industrial products. The sizes of LCM includes 1.4”, 2.4”, 3.5", 3.51", 4.3", 4", 5", 7", 8", 10.1” and 11.6". And among them the 3.5”, 4.3", 5", 7” and 10.1" LCM has achieved the leading level of the industry, and mainly applied to vehicle-applications, tablet PCs, smartphones, medical equipment, measurement equipment, E-books, EPC and industrial products, and provides powerful and reliable supports on supplies and qualities. We are cooperating with famous foreign companies on research and developments, and will bring out the series products of industrial control. Also, we explore the overseas market, and build up a long-term relationship with our overseas partners and agents, Leadtek products will be worldwide in the near future.

For our first project, we’re using both the inbuilt LCD screen and WiFi module to get text data of famous quotes. Since we’re all nerds at DIYODE, we’ve of course chosen to choose famous programming quotes. The center button of the Wio Terminal will be used to load a new quote and display it on the screen.

There isn’t a ton of libraries we need to import here. We’re using the Arduino JSON, rpcWiFi and HTTPClient libraries to handle the internet connection and data, and the TFT_eSPI library to handle the screen on the Wio Terminal.

The ‘wasPressed’ variable will be used during the main loop to ensure we only display one new quote when the button is pressed, and not to continue looking for quotes when the button is held. This is typically referred to as state detection, and we’ll talk about this shortly.void setup() {

Our setup code is verbose but should be fairly self-explanatory as we read through it. We’re starting the TFT screen and setting its rotation, background settings and a placeholder text while we wait for a connection to the WiFi.

Text wrapping is the process of bringing text fields down to the next line on the screen if it’s too long – which is often the case with quotes. The LCD library does have this function built-in, but it wasn’t cooperating for us, so we wrote it ourselves!

Essentially, we’re taking ‘chunks’ out of the text with the substring function and writing each to one line of the Wio Terminal’s LCD screen. The ‘len’ variable describes the number of characters on each line. If the function is confusing, just change some values and observe the effects!

…and boom! It’s all working. Inspiring programming quotes at the press of a button. Obviously, this isn’t the most practical program ever – but it’s a good starting program to experiment with the Wio Terminal and to demonstrate its capabilities with precisely zero external wiring required.

Our company is committed to the customization service, R&D, sale and after-sales service of LCD and TFT display products.At present, our company has a team of more than 100 employees. Our products include monochrome LCD (TN and STN), color LCD (CSTN and TFT) and LCD modules (both COG and COB).

But there is a plot twist. The used microcontroller (ESP8266) can go to sleep for only 3 hours and 25 minutes (according to the Internet --- see IV.Credits --- ). So I decided to wake up the microcontroller after the before mentioned time (3 hours and 25 minutes) and then put it back to sleep. This will be done 7 times (a total of 23 hours). To keep track of the numbers of wake-ups between 2 quotes, I saved a counter in the RTC user memory from the ESP8266 ( --- see IV.Credits --- ). In this way, when the microcontroller goes to sleep the counter will be kept.
