raspberry pi tft lcd spi made in china

To interface any random piece of hardware with a raspberry pi you need to know a few things 1) voltage limits, 2) pinout (you can kill any device by swapping GND and Vcc, 3) the interface (SPI, I2C, 1-wire, USB, 8-bit) and 4) the bytes you need to send to the device to control it.

The makers of reliable, well documented devices publish all of that information in a document called a datasheet. It tells you what you need to know to a) wire it to your RPi and b) drive it from software.

For something random bought from some unknown Chinese vendor on eBay you may not get that info. For something bought from Adafruit or CPC/Farnell/Element14 you are 100% guaranteed to get the datasheet, you may even get pictorial wiring diagrams and software code samples to drive the devices they"re selling.

※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.

The TTL serial Nextion display is the best balance HMI solution between cost and benefit with low and decreased learning curve. See Nextion Editor Guide and Instruction Set.

First of all, a happy new 2023! I"ll use this occasion to introduce a new type of Sunday blog post: From now on, every now and then, I"ll publish a collection of FAQ around a specific topic, to compile support requests, forum posts, and questions asked in social media or by email...Whatever you are currently celebrating, Christmas, Hanukkah, Jul, Samhain, Festivus, or any other end-of-the-civil-year festivities, I wish you a good time! This December 25th edition of the Nextion Sunday Blog won"t be loaded with complex mathematical theory or hyper-efficient but difficult to understand code snippets. It"s about news and information. Please read below...After two theory-loaded blog posts about handling data array-like in strings (Strings, arrays, and the less known sp(lit)str(ing) function and Strings & arrays - continued) which you are highly recommended to read before continuing here, if you haven"t already, it"s big time to see how things work in practice! We"ll use a string variable as a lookup lookup table containing data of one single wave period and add this repeatedly to a waveform component until it"s full.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...

Long time enjoyer of this driver. Truly awesome. Generally I"m using it with an ILI9341 generic from Hiletgo Amazon, However I just got a new screen from China (an ST7789 according to specs) that"s an 8 pin SPI TFT OLED display. No matter my wiring or my command lines, it just does not want to work. I"ve got to the point where the Reset pin will light up the backlight but it wont" go any further.

Command: cmake -DST7789=ON -DGPIO_TFT_DATA_CONTROL=25 -DGPIO_TFT_RESET_PIN=24 -DGPIO_TFT_BACKLIGHT=23 -DSPI_BUS_CLOCK_DIVISOR=40 -DUSE_DMA_TRANSFERS=ON -DDISPLAY_BREAK_ASPECT_RATIO_WHEN_SCALING=ON ..

Everything compiles just fine and even turns on the backlight, but there still is a black screen. The only thing I"ve changed in config.h was to uncomment // #define UPDATE_FRAMES_WITHOUT_DIFFING and completely rebuild the build file.

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.

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!

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!
