fullvision tft display free sample

This new library is a standalone library that contains the TFT driver as well as the graphics functions and fonts that were in the GFX library. This library has significant performance improvements when used with an UNO (or ATmega328 based Arduino) and MEGA.

Examples are included with the library, including graphics test programs. The example sketch TFT_Rainbow_one shows different ways of using the font support functions. This library now supports the "print" library so the formatting features of the "print" library can be used, for example to print to the TFT in Hexadecimal, for example:

To use the F_AS_T performance option the ILI9341 based display must be connected to an MEGA as follows:MEGA +5V to display pin 1 (VCC) and pin 8 (LED) UNO 0V (GND) to display pin 2 (GND)

TFT_ILI9341 library updated on 1st July 2015 to version 12, this latest version is attached here to step 8:Minor bug when rendering letter "T" in font 4 without background fixed

The ADS5012H is a versatile, highly practical, cost-effective handheld oscilloscope for the maintenance industry and the R&D industry with DANIU"s real-time sampling rate of up to 500MS/s and 100MHz analog bandwidth. With full trigger function ( single, normal , automatic ), it can be used freely for both periodic analog signals and non-periodic digital signals. The built-in high voltage protection module can withstand up to 400V continuous voltage and 600V peak voltage. There is no need to worry about the oscilloscope Burnout caused by the high voltage not being probed to the 10X position. Large time base scan mode that monitors slow level changes. Equipped with high-efficiency one-button AUTO, the measured waveform can be displayed without complicated adjustment. Display high-definition LCD Screen with 2.4-inch 320 x 240 resolution TFT full-vision technology, the visual effect is very good. Extremely convenient and fast waveform storage function, built-in 64M storage space, can store up To 2000 waveform pictures, the storage process is simple and fast, save the current waveform anytime and anywhere, just one touch, no cumbersome tips and choices. Powerful waveform file manager, support for thumbnail browsing, viewing, detail viewing, page turning, deletion And more. Built-in 3000mah high-quality lithium battery, can be used continuously for 8 hours when fully charged. The body is equipped with high-quality silicone protective cover, non-toxic and lead-free environmental protection, anti-skid, Anti-shock and shockproof, comprehensive protection of the fuselage, soft texture, feel very comfortable.

TFT LCD image retention we also call it "Burn-in". In CRT displays, this caused the phosphorus to be worn and the patterns to be burnt in to the display. But the term "burn in" is a bit misleading in LCD screen. There is no actual burning or heat involved. When you meet TFT LCD burn in problem, how do you solve it?

Burn in is a noticeable discoloration of ghosting of a previous image on a display. It is caused by the continuons drive of certain pixels more than other pixels. Do you know how does burn in happen?

When driving the TFT LCD display pixels Continously, the slightly unbalanced AC will attract free ions to the pixels internal surface. Those ions act like an addition DC with the AC driving voltage.

Those burn-in fixers, screen fixer software may help. Once the Image Retention happened on a TFT, it may easy to appear again. So we need to take preventive actions to avoid burn in reappearing.

For normal white TFT LCD, white area presenting minimal drive, black area presenting maximum drive. Free ions inside the TFT may are attracted towards the black area (maximum drive area)

When the display content changed to full screen of 128(50%) gray color, all the area are driving at the same level. Those ions are free again after a short time;
