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.

Well, I bought a Chinese LCD TFT touchscreen, 3.5 inches, but I cant get it working, because I cant find the drivers. The only thing it says in the back is www.mcufriend.com, but the page is not available. I tried following this tutorial, but the screen only appears white.

A few weeks ago, I wrote this article about using a text variable as an array, either an array of strings or an array of numbers, using the covx conversion function in addition for the latter, to extract single elements with the help of the spstr function. It"s a convenient and almost a "one fits all" solution for most use cases and many of the demo projects or the sample code attached to the Nextion Sunday Blog articles made use of it, sometimes even without mentioning it explicitly since it"s almost self-explaining. Then, I got a message from a reader, writing: "... Why then didn"t you use it for the combined sine / cosine lookup table in the flicker free turbo gauge project?"105 editions of the Nextion Sunday blog in a little over two years - time to look back and forth at the same time. Was all the stuff I wrote about interesting for my readers? Is it possible at all to satisfy everybody - hobbyists, makers, and professionals - at the same time? Are people (re-)using the many many HMI demo projects and code snippets? Is anybody interested in the explanation of all the underlying basics like the algorithms for calculating square roots and trigonometric functions with Nextion"s purely integer based language? Are optimized code snippets which allow to save a few milliseconds here and there helpful to other developers?Looking through the different Nextion user groups on social networks, the Nextion user forum and a few not so official but Nextion related forums can be surprising. Sometimes, Nextion newbies ask questions or have issues although the required function is well (in a condensed manner for the experienced developer, I admit) documented on the Nextion Instruction Set page, accessible through the menu of this website. On top of that, there is for sure one of my more than 100 Sunday blog articles which deals not only with that function, but goes often even beyond the usual usage of it. Apparently, I should sometimes move away from always trying to push the limits and listen to the "back to the roots!" calls by my potential readers...Do you remember the (almost) full screen sized flicker free and ultra rapid gauge we designed in June? And this without using the built-in Gauge component? If not, it"s time to read this article first, to understand today"s improvements. The June 2022 version does its job perfectly, the needle movement is quick and smooth, and other components can be added close to the outer circle without flickering since there is no background which needs constantly to be redrawn. But there was a minor and only esthetic weak point: The needle was a 1px thin line, sometimes difficult to see. Thus, already a short time after publishing, some readers contacted me and asked if there were a way to make the needle thicker, at least 2 pixels.Recently, when playing with a ESP32 based NodeMCU 32S and especially with its WiFi configuration, I did as (I guess) everybody does: I loaded an example sketch to learn more about the Wifi library. When you set up the ESP32 as an access point, creating its own wireless network, everything is pretty straightforward. You can easily hard code the Wifi name (SSID) and the password. But what about the client mode ? Perhaps one needs to use it in different environments. And then, a hard coded network name and password are definitively not the best solution. Thus, I thought, why not use a Nextion HMI for a dynamic WiFi setup functionality?Although the Nextion MIDI I/O interface  has been primarily designed as an add-on for Nextion HMI screens to transform these in fully autonomous MIDI devices as shown in previous blog posts here, it is also of great use for any Arduino based electronic music project! Many MIDI projects for Arduino suffer from a lack good hardware support. There are sophisticated code, excellent libraries and an infinity of use cases, but afterwards, things tend not to work in a rather rough environment in the studio or on stage. That"s because two resistors and a few Dupont wires on a breadboard besides the Arduino are not really an interface which could drive your Synth, Sequencer, or Drum machine over a 5m long MIDI cable.

Science fiction has always served as a window into a potential future, namely in the way of technology. But what was once regulated to episodes of Star Trek is quickly becoming the stuff of reality. Many fixtures of these kinds of shows and books have begun to inspire real-life counterparts, including - but not limited to - touchscreen technology.

One only has to look at how far cell phones have come since their inception. Physical keyboards, like those from BlackBerry, gave people about as much of a solution as is possible for those who found themselves doing more on the devices as they became more advanced. Where tactile options came up short, touchscreens graciously stepped up to bat, providing a much fuller experience. This kind of functionality then spread to tablets, which are considered by many to be rivals of laptops and even standard PCs.

While there are still some things that are best done on a desktop computer, that does not change the fact that many users find themselves longing for the same abilities on their PCs afforded by many of their mobile devices. This is what helped breed the touchscreen monitor market, which has many viable options for people seeking the best of both worlds. With stronger computing power and a finer ability to control actions occurring in the screen, users can get more work done in new and exciting ways.

Traditionally, computer mice are what have allowed us to "touch" in a virtual context, but touchscreen monitors are changing all that. It might be said that the reason that mice were used in the first place was because the technology had not evolved to a responsive enough level to enable that natural solution. Now that people have the touchscreen technology, they want it everywhere.

If one thing is for certain, it is that the burgeoning adoption of touchscreen technology is no fad. Proliferation has already come too far to turn back now, and computer manufacturers are taking notice. Everyone is trying to get a piece of the action, including ELO Touch Solutions, Laiputuo Electronics, Planar, HP, 3M, Touch Systems, ViewSonic, Dell and ACER as well. Getting into the touchscreen monitor game is a no-brainer for the companies involved in this generation of computing. With so many different applications made for touchscreen monitors, options exist for all sorts of interested parties.

Touchscreen monitors are becoming the new standard in both private and enterprise settings. Here are some of the ways they can be leveraged effectively for business: touchscreen monitors for workstations, touchscreen monitors for hospitals, and touchscreen monitors for POS systems.

Newegg offers a large selection of touchscreen monitors which vary according to the type from 5-wire Resistive touchscreen monitors, and Accu Touch touchscreen monitors, to Capacitive touchscreen monitors, and more. Newegg’s wide selections will definitely meet your needs.

This screen is located on this site. Since overlays already exist for this display in the /boot/overlays directory, it will be supported with a simple configuration.

This screen uses the SPI bus to be driven. Its low resolution allows us to get a good frame rate in the emulation frequencies. Not really 60fps, but more than the minimum of 30 fps thanks to the modified fcbp program.

The SPI bus speed must be adjusted if you overclock your Raspberry Pi to get a good image. These settings have been tested on a Raspberry Pi1 at 1.1Ghz.

If you are using the GPIO controllers, you can instead change the GPIO pin configuration by using pin 4 or 5 to set the pin used, avoiding the pins used by your display. See here for details.

This 2.8" screen works well but may be too small and too expensive (35€) as far as Chinese clones are concerned. So let"s configure a 3.2" TFT screen from Waveshare that can be found on Banggood for less than 15€.

The screen is the following: a 3.2" TFT LCD touchscreen display module for the Raspberry Pi B+, B, A+. Its resolution is the same as the 2.8": 320x240. It is in fact a Waveshare screen.

Get the files waveshare35a-overlay.dtb and waveshare32b-overlay.dtb for the WaveShare 3.2" 320x240 display and the WaveShare 3.5" 320x480 display respectively. For the new version 4.4 kernels, we need to rename the dtb files to dtbo files to match the new overlay tree name. Rename waveshare35a-overlay.dtb to waveshare35a.dtbo and waveshare32b-overlay.dtb to waveshare32b.dtbo and copy them to the /boot/overlays directory.

If you are using the GPIO controllers, you can instead change the GPIO pin configuration by using pin 4 or 5 to set the pin used, avoiding the pins used by your display. See here for details.

This display cannot be used for arcade games with Recalbox. The SPI bus does not have enough bandwidth to handle this higher resolution of 480x320. If you increase the bus speed, the display becomes unstable (colors, flickering). During my tests, I could only get 20-25 FPS. This display is usable with an X server with a slow frame rate but not in arcade mode which requires a higher frame rate.

As described on this site, it is not recommended to use this screen for gaming. With twice as many pixels to push on the screen, the PiTFT 3.5" is significantly slower than its more compact brothers and we strongly advise against it for games. Now you know!

Get the files waveshare35a-overlay.dtb and waveshare32b-overlay.dtb for the WaveShare 3.2" 320x240 screen and the WaveShare 3.5" 320x480 screen respectively. For the new version 4.4 kernels, we need to rename the dtb files to dtbo files to match the new overlay tree name. Rename waveshare35a-overlay.dtb to waveshare35a.dtbo and waveshare32b-overlay.dtb to waveshare32b.dtbo and copy them to the /boot/overlays directory

If you are using the GPIO controllers, you can instead change the GPIO pin configuration by using pin 4 or 5 to set the pin used, avoiding the pins used by your display. See here for details.

In my humble opinion, if you have the 3.5" (C) LCD for Raspberry Pi (480x320; 125Mhz), it should work, but with the 3.5" (B) LCD for Raspberry Pi (480x320; IPS), you won"t be able to get 60fps!
