tft display with pi zero supplier

This is 2.8 inch Touchscreen for Raspberry Pi Zero or Zero W, comes with 640x480 Resolution, 60+fps and you can install driver to use the screen and touch.

Note:In fact, this screen fits to Raspberry Pi 3B/2B/B+; but you must use the bread cables to connect them, because it"s male pins on the this screen, and it"s male pins on the pi 3B/B+ too.

The frame buffer is a memory buffer mapping all the pixels of the screen. Our screen"s resolution is 480x320, and each color is coded on 2 bytes, so it"s simply a 480x320x2 bytes buffer, so we have to write the pixel color at the proper buffer position to have this pixel displayed on the screen.

As said, the screen displays only 65536 colors, so each pixel is coded on 16 bits, using the RGB565 format ( 5 bits for red, 6 bits for green, 5 bits for blue ), here is the way to convert standard 24 bits RGB to 16 bits RGB565 :

I found a nice 8x8 pixels font here and made a few executables to use in scripts. You"ll find my code attached, or you can simply clone it from GitHub and build the various executables :git clone https://github.com/SamuelF94/fbdisplay

I’ve been struggling over the past few weeks to get a 3.5" TFT display to work on a Zero W. I have 2 different displays and 2 Raspberry Pi Zero W boards that I’ve been playing with. From what I’ve read the display “should just work” with the hestia-pi-touch image, but all I get is a blank display. I’ve tried different clean versions of raspbian from wheezy to buster with every display driver I could find with no luck.

Am I missing something obvious? Most of the pages I’ve found detailing the process say you should see SOMETHING on the display after installing the drivers & rebooting. Of course the display vendors have been 100% useless providing any help.

All fans of Raspberry Pi perfectly understand the phenomenon of Raspberry, which has enthusiasts in many areas. It is used in everyday life, but also in robotics, programming and industry. Raspberry Pi is perfect for modern intelligent building systems. It can be expanded with various types of peripheral devices, acquiring specific features. Among them there are displays, which are available in our offer in different versions. They come in 0.9", 1.3", 1.44", 1.54", 2", 2", 2.13", 2.2", 2.4", 2.6", 2.7", 2.8", 3.2", 3.5", 4", 4.,2", 4.3", 5", 5.83", 7", 7.50", 10", 10.1", 11.1" and 14" screens. They also differ in the technology used, which ensures a specific image quality. We offer LED and OLED matrix displays, monochrome and segmented, consisting of LEDs, e-paper, alphanumeric displays as well as LCD IPS, LCD TFT. The displays work with boards using GPIO+DPI, HDMI, HDMI+GPIO, HDMI+USB, DSI, GPIO, I2C, SPI, SPI + I2C, as well as USB. The interface through which the screen connects to the Raspberry Pi module must be operable, otherwise there is a risk of interference and the connection quality will be poor.

We offer screens dedicated for special housings as well as modular laptops based on Raspberry Pi. If you use the display and your Raspberry frequently, an e-paper display is a good choice for you, which is more convenient for human eyesight. It has other advantages, it is very energy-efficient, consumes little energy, so it will be a good choice for those who are still looking for savings, while increasing the comfort of their daily life.

The displays can be used on a daily basis as well as for large robotics and electrical projects. They can be used for information purposes, displaying current data with the parameters of the specific equipment or system with which they work. This function is very often performed by monochrome and segment displays. Or maybe you would like to create your own e-book reader. You will need an energy-saving and eye-safe e-paper display. Touchscreens are very well suited for game controllers and drawing devices. The use of Raspberry Pi displays is therefore very wide.

Adjust the type of display to your design and purpose. Decide on the option that best matches your expectations and needs. Build your Raspberry Pi, make an ambitious project or simply use the Raspberry Pi as an alternative to your laptop or iconic PC.

Why the LCD doesn"t work with my Raspbian?To use the LCD with the Raspberry Pi official image, driver (SPI touch interface only) should be installed first. Please refer to the user manual.

However, for the first testing, you may want to use our image directly (if provided).Why the LCD still doesn"t work with the Waveshare provided image?Make sure the hardware connection is correct and connects fine.

The PWR will keep on and the ACT will keep blinking when the Raspberry Pi starts up successfully, in case both of the two LEDs keep on, it is possible that the image was burnt incorrectly OR the TF card was in bad contact.Which power supply should I use?It is recommended to use a 5V/3A power adapter for the Raspberry Pi other than USB connection, otherwise the Pi may failed to start up because the PC"s USB port might have not enough power.

Since the first-generation Raspberry Pi released, Waveshare has been working on designing, developing, and producing various fantastic touch LCDs for the Pi. Unfortunately, there are quite a few pirated/knock-off products in the market. They"re usually some poor copies of our early hardware revisions, and comes with none support service.
