rpi tft lcd v3.0 price
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.
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.
For smaller projects, LCD and ePaper displays are a fun way to add a visual element to your projects. With simple code and wiring, they’re great for projects that require text, menus and navigation.
※Price Increase NotificationThe TFT glass cell makers such as Tianma,Hanstar,BOE,Innolux has reduced or stopped the production of small and medium-sized tft glass cell from August-2020 due to the low profit and focus on the size of LCD TV,Tablet PC and Smart Phone .It results the glass cell price in the market is extremely high,and the same situation happens in IC industry.We deeply regret that rapidly rising costs for glass cell and controller IC necessitate our raising the price of tft display.We have made every attempt to avoid the increase, we could accept no profit from the beginning,but the price is going up frequently ,we"re now losing a lot of money. We have no choice if we want to survive. There is no certain answer for when the price would go back to the normal.We guess it will take at least 6 months until these glass cell and semiconductor manufacturing companies recover the production schedule.

It"s also ideal for Raspberry PI by HDMI.
For reference, I did create the Waveshare_ILI9486 wrapper library which has been tested on the UNO/Mega with genuine Waveshare SPI shift-register based displays (including a basic GFX-style interface). As David points out, it is possible that your board may work with a Waveshare-style driver. Note that I have not yet tested the above library on any of the RPI board variants (so anshumantech"s test result is not surprising). I don"t recall seeing a schematic or know how the RPI A,B,C variants may differ, but assuming it is still ILI9486-based via 16b shift regs, perhaps some small tweaks to the library or pin connectivity might enable it to work.

Step 3: insert the Micro SD card into the Raspberry Pi, connect the HDMI cable to the Raspberry Pi and the LCD, connect the USB cable to any of the 4 USB ports of the Raspberry Pi, connect the other end of the USB cable to the USB port of the LCD, and then give the Raspberry Pi Power-on. If the display and touch are normal, the drive is successful (please use the 2A power supply).
2. Connect one end of the MicroUSB cable to the USB Touch interface of the LCD (any of the two MicroUSBs) and the other end to the USB port of the computer.
This LCD Touchscreen HAT fits snuggly on top of the Raspberry Pi, practically form fitting on top of it so as not to compromise the overall dimensions of the credit card sized single board computer. The resistive touchscreen provides you with an easy way to display information coming off of the Raspberry Pi and the OS currently running on it.
The 4:3 aspect ratio backlit LCD equipped on this HAT possesses a resolution of 480 by 320 pixels with over 65 thousand colors and an SPI interface with a 16MHz driver speed. Simply plug the 13x2 GPIO header into your desired Raspberry Pi and you"ll be able to start using your new resistive touch screen!
I just finished two solid days of work trying to get an HDMI LCD panel working with one of the inexpensive older model TFT LCD displays in a "Dual mode" configuration. There was a tremendous amount of help from this post, which got me most of the way there, but the infamous "last mile" still took me a while. I"m leaving some breadcrumbs here, as well as asking the group if anyone knows of a better way.
I am working on a device that uses a Raspberry Pi 4 as an embedded controller. For output, I need an 2K DSI LCD w/ its own HDMI adapter (Sharp LS055R1SX04, about $65 USD), as well as an inexpensive TFT LCD used for a basic touch user interface. The TFT LCD, which uses an ILI9341 LCD controller and an ads7846 touchscreen controller, can be had for about $10 USD. The Pi was flashed with the latest Raspberry Pi OS 32 bit then updated, so everything is current as of this writing (March 2021).
Initial configuration of the display worked with little issue. The HDMI adapter for the Sharp LCD works at 50 Hz only, so it requires custom timings. The TFT LCD uses the same controller chips as the original 3.5" Raspberry Pi LCD, so I was able to activate it with the rpi-display dtoverlay.
Booting with the above correctly revealed two framebuffer devices listed with ls -l /dev/fb*. The display initially showed as all white, then went all black, indicating correct initialization. However, when starting the desktop GUI, only the Sharp LCD showed any contents, and only it was listed as a device by xrandr.
Based on claims of the above not being "ideal", I experimented with various settings. If the above file is deleted entirely, xrandr reports the Sharp LCD as the sole display. If you put the above file in place, and remove all references to the Sharp LCD (including the Device, Monitor, Screen, and ServerLayouts), xrandr correctly reports the TFT LCD, but not the Sharp LCD. I left JUST the Device sections in, but xrandr failed to correctly report one of the other.
Since xrandr was INOP in this configuration, I could not use xinput --map-to-output to limit touchscreen coordinates to the TFT LCD. Instead, I settled on using a combination of touch screen rotation, and input coordinate translation:
Note that the TransformationMatrix is very specific to a 1440x2560 in portrait mode with 320x240 in landscape mode to the right of the Sharp LCD. The numbers are basically:
My question to the group, if anyone knows, is simple: is it possible to configure a Pi4 so an SPI connected LCD can co-exist without disabling the RandR extension in X11?

As I mentioned in my initial post, what "works" for me is the "rpi-display" overlay. If I execute fdtdump /boot/overlays/rpi-display.dtbo on my current configuration, I see this fragement:
I"m not real familiar with this stuff (I stumbled across it while I was stuck in the mud), but I assume by these results that there are two different drivers possible: fb_ili9341 which is the framebuffer version, and ili9341 which I assume is the DRM version. If I understand how this all fits together, it appears that when I select the "rpi-display" overlay, its picking the framebuffer version due to the last line in modules.alias?
Adding "tinydrm" to my google searches revealed this Github issue: https://github.com/notro/tinydrm/issues/14, and it mentions in passing "here is an example overlay source file", pointing to the rpi-display overlay. However, when I look at the referenced source, https://github.com/notro/tinydrm/blob/m ... verlay.dts, it contains this:
However it is as I suspected - we have no mouse pointer on the TFT screen, presumably as X can"t cope with one display having a cursor plane and the other not. I don"t know the best way to overcome that.
Which sounds like yours (i.e the "Unknown19-1). I got the "lock up" again, but it turns out that lock-up was actually VNC (I"ve been using that to develop, as the text on a Sharp LCD is VERY tiny to look at in desktop mode). My console was still alive, so I hooked up an actual keyboard and mouse to the Pi, and the desktop on my Sharp LCD came alive. With the above two commands you"ve discovered, I now have two desktops. Sort of...
It appears as if the upper left hand corner of my Sharp LCD desktop is mirrored on the small LCD. It"s not two independent desktops. Instead, it"s the same desktop duplicated. I suspect that is probably more X configuration than driver stuff, however.
