waveshare 1.44 inch lcd display hat for raspberry pi install brands

The ST7735S is a 132*162 pixel LCD controller, but the pixel of the 1.44inch LCD HAT is 128*128. So we have made some processing on the display: the horizontal direction starts from the second pixel to guarantee the location of RAM in the LCD is consistent with the actual location at the same time.

Note: Different from the traditional SPI protocol, the data line from the slave to the master is hidden since the device only has a display requirement.

The final display effect is scaled and displayed on the 1.3inch LCD in proportion. The setting of the resolution here should be slightly larger than the LCD resolution, the too high resolution will cause the font display to be blurred.

【Note】The mouse.py needs to run under the graphical interface, which will not run under the SSH login. You can skip this step directly, the Pi will run the demo automatically by booting up.

Be careful not to add it to /etc/rc.local, because rc.local will be executed before the system enters the desktop, and if the PyMouse module runs on the command line interface, it will report an error that there is no mouse event, so we need to execute the following:

If fbtft is turned on, spidev0.0 will be occupied after restarting. If you need to run the demo at this time, you need to comment out the lines corresponding to fb in /etc/modules.

This is a LCD display HAT for Raspberry Pi, 1.44inch diagonal, 128x128 pixels, with embedded controller, communicating via SPI interface. It also comes with three push button and a joystick, a good option as user interface panel for your Raspberry Pi Zero :)

The RPi LCD can be driven in two ways: Method 1. install a driver to your Raspbian OS. Method 2. use the Ready-to-use image file of which the LCD driver was pre-installed.

2) Connect the TF card to the PC, open the Win32DiskImager software, select the system image downloaded in step 1 and click‘Write’ to write the system image. ( How to write an image to a micro SD card for your Pi? See RPi Image Installation Guides for more details)

3) Connect the TF card to the Raspberry Pi, start the Raspberry Pi. The LCD will display after booting up, and then log in to the Raspberry Pi terminal,(You may need to connect a keyboard and HDMI LCD to Pi for driver installing, or log in remotely with SSH)

1. Executing apt-get upgrade will cause the LCD to fail to work properly. In this case, you need to edit the config.txt file in the SD card and delete this sentence: dtoverlay=ads7846.

This LCD can be calibrated through the xinput-calibrator program. Note: The Raspberry Pi must be connected to the network, or else the program won"t be successfully installed.

I recently purchased the tiny 1.44 inch LCD screen from Waveshare and placed it atop an Pi Zero that I had. I really wanted the screen to be a clock, so I made one below. Feel free to use and improve upon it. You can replace the numbers with your own numbers if you would like. I wanted to go for the OCR font face look, so used the images included in below install. I used the solderless GPIO connector to connect the Pi Zero to the LCD hat, but you can also do it the old fashioned way and solder the connector to the Pi Zero.

Choose Interfacing Options -> SPI -> Yes to enable SPI interface. Then, Waveshare recommends you perform the following to setup their hat. Not sure this is really needed for this project, but I followed their instructions. It certainly does not interfere in any negative way with this project:wget http://www.airspayce.com/mikem/bcm2835/bcm2835-1.68.tar.gz

Finally, you need to install my very short python code for the clock. You can change the numbers if you would like, as long as you make 10 separate .bmp files with an image size of 64x64 pixels for all the numbers from 0 to 9. Just replace the ones that you install below.sudo wget https://alpserver.ch/clock.zip

And you"re done! The Pi Zero will boot up with the clock on the LCD hat, and you can still use the Pi as a computer or server or whatever you would like. Hope you enjoy it as much as I do!
