pi tft lcd 3.5 made in china
After snapping the board, case, usb adapters for wifi and wireless keyboard, plugging in hdmi and power, nothing happened. A red light on the board lit up, but nothing else. I went online and after some googling, I found out that if no OS is recognized, nothing will display on your TV/monitor. I unplugged the power, took out the SD card and re-inserted, and the system booted into NOOBS.
I chose to install RaspBMC. The install went fine, the system rebooted to an XBMC screen that had a slight pink glow over the entire screen. More googling, and realized the board may not be outputting enough power through the HDMI port. There is info online for configuring a config file so more power goes to HDMI. I couldn"t get to this file from the SD card plugged into my laptop because Noobs makes this partition not viewable under Windows.
Shut it all down. Googled how to remove all partitions on an SD card from Windows command prompt with the diskpart function and formatted the SD card to one big FAT32 4GB partition. Went to the OpenELEC website and downloaded and installed the OpenELEC image for the Raspberry Pi. Booted into the XBMC version of OpenElec, configured wifi and other settings. Tested by watching both 1080p and 720p content streaming from a local network drive and from over the internet.
3.5inch RPi LCD (A) and 3.5inch RPi LCD (B) are hardware compatible with each other (uses different driver), and can be mutually substituted in most cases. (A) for low cost ver. while (B) for IPS ver. with better displaying.
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.
Nextion is a Seamless Human Machine Interface (HMI) solution that provides a control and visualisation interface between a human and a process, machine, application or appliance. Nextion is mainly applied to IoT or consumer electronics field. It is the best solution to replace the traditional LCD and LED Nixie tube.
This solution includes hardware part - a series of TFT boards and software part - Nextion editor. Nextion TFT board uses only one serial port to do communicating. Let you get rid of the wiring trouble. We notice that most engineers spend much time in application development but get unpleasant results.
In this situation, Nextion editor has mass components such as button, text, progress bar, slider, instrument panel etc. to enrich your interface design. And the drag-and-drop function ensures that you spend less time in programming, which will reduce your 99% development workloads. With the help of this WYSIWYG editor, GUI designing is a piece of cake.
This is a powerful 3.5"" HMI, which is member of Nextion family. Features include: a 3.5" TFT 480 x320 resistive touch screen display, 4M Flash, 2KByte RAM, 65k colors.
