2.2 lcd module free sample

If you already have experience with the rectangular LCD modules, you will gain one more experience here: namely the round LCD module which is the size of a men"s wristwatch. DFRobot offers it with example-codes for ESP and Arduino as Fermion: 2.2 ”TFT SPI Interface LCD Display (Breakout).

A graphic could also be converted into hex values with a desktop program and displayed accordingly on the LCD. However, I am inexperienced in using the Chinese characters and have not tried the example program.

A full color 240xRGBx320 pixel TFT display module with 2.2" diagonal active area. Very small text and images look sharp on this graphic display, with its dense pixel pitch of 0.141 x 0.141 millimeters. The TFT"s 6:00 o" clock viewing direction works well for devices that must be easy to read above eye level without fading, such as signal analyzers or other benchtop laboratory equipment.

In these videos, the SPI (GPIO) bus is referred to being the bottleneck. SPI based displays update over a serial data bus, transmitting one bit per clock cycle on the bus. A 320x240x16bpp display hence requires a SPI bus clock rate of 73.728MHz to achieve a full 60fps refresh frequency. Not many SPI LCD controllers can communicate this fast in practice, but are constrained to e.g. a 16-50MHz SPI bus clock speed, capping the maximum update rate significantly. Can we do anything about this?

-DPIRATE_AUDIO_ST7789_HAT=ON: If specified, targets a Pirate Audio 240x240, 1.3inch IPS LCD display HAT for Raspberry Pi with ST7789 display controller

-DKEDEI_V63_MPI3501=ON: If specified, targets a KeDei 3.5 inch SPI TFTLCD 480*320 16bit/18bit version 6.3 2018/4/9 display with MPI3501 display controller.

-DSINGLE_CORE_BOARD=ON: Pass this option if you are running on a Pi that has only one hardware thread (Pi Model A, Pi Model B, Compute Module 1, Pi Zero/Zero W). If not present, autodetected.

I don"t know, I don"t currently have any to test. Perhaps the code does need some model specific configuration, or perhaps it might work out of the box. I only have Pi 3B, Pi 3B+, Pi Zero W and a Pi 3 Compute Module based systems to experiment on. Pi 2 B has been reported to work by users (#17).

This suggests that the power line or the backlight line might not be properly connected. Or if the backlight connects to a GPIO pin on the Pi (and not a voltage pin), then it may be that the pin is not in correct state for the backlight to turn on. Most of the LCD TFT displays I have immediately light up their backlight when they receive power. The Tontec one has a backlight GPIO pin that boots up high but must be pulled low to activate the backlight. OLED displays on the other hand seem to stay all black even after they do get power, while waiting for their initialization to be performed, so for OLEDs it may be normal for nothing to show up on the screen immediately after boot.

Implement a kernel module that enables userland programs to allocate DMA channels, which fbcp-ili9341 could use to amicably reserve its own DMA channels without danger of conflicting.

The ST7789 TFT module contains a display controller with the same name: ST7789. It’s a color display that uses SPI interface protocol and requires 3, 4 or 5 control pins, it’s low cost and easy to use. This display is an IPS display, it comes in different sizes (1.3″, 1.54″ …) but all of them should have the same resolution of 240×240 pixel, this means it has 57600 pixels. This module works with 3.3V only and it doesn’t support 5V (not 5V tolerant).

The ST7789 display module shown in project circuit diagram has 7 pins: (from right to left): GND (ground), VCC, SCL (serial clock), SDA (serial data), RES (reset), DC (or D/C: data/command) and BLK (back light).

As mentioned above, the ST7789 TFT display controller works with 3.3V only (power supply and control lines). The display module is supplied with 3.3V (between VCC and GND) which comes from the Arduino board.

To connect the Arduino to the display module, I used voltage divider for each line which means there are 4 voltage dividers. Each voltage divider consists of 2.2k and 3.3k resistors, this drops the 5V into 3V which is sufficient.
