raspberry pi 1.8 tft display manufacturer

The 1.8" TFT LCD SPI-bus display modules available from Adafruit and SainSmart are functionally equivalent, except that the SainSmart unit can be driven at a much faster SPI bus rate than the Adafruit (32 MHz vs. 4 MHz in my testing). Fabien Royer has shown that this is due to a slow level shifter in the Adafruit unit.

The original st7735fb kernel driver was by Matt Porter, and was enhanced by Lady Ada, Neil Greatorex, and myself. I started with Neil"s proposed version of Matt"s st7735fb driver, which I extracted from Lady Ada"s raspberrypi kernel repo. I applied Neil"s version to the current raspberrypi 3.2.27+ kernel, then I made multiple enhancements to the st7735fb driver (and fixed a glitch in the bcm2708 SPI driver). I"ve since collaborated with Neil to develop further enhancements, and ported the driver to the upcoming 3.6.y Raspberry Pi kernel.

* My version of the st7735fb_map driver allows either CE0 (SPI 0.0) or CE1 (SPI 0.1) to be configured. ** My version allows the configuration of any GPIO pin for D/C and RESET. *** Since I"m not using the MicroSD card device on the back of the display modules, the remaining pins are left unconnected.

Clone my raspberrypi-linux repo, then select either the 3.2.27-based branch or the 3.6.y-based branch (run "uname -a" on your Pi if you"re not sure which you need):

The st7735fb driver supports fbcon which attaches the display as tty1 and/or other VT"s so the standard getty login will appear without any additional configuration. The following alternate method using fbterm also works, but is more complex to configure.

The board supports multiple different 1.8" panel pinouts including Adafruit and SainSmart, and sports mounting pads for three GPIO buttons. Very nice!

The TFT isn"t "plug & play" with the Raspberry, a patch has to be applied to the kernel to be able to interface via SPI with the ST7735R controller chip on the TFT. Once working, the display will act as a framebuffer device.

As it takes over three hours to compile the kernel on the PI, I will show how to cross compile from another Linux PC. In my case, it is Ubuntu 12.10 running within VMWare on a Windows 7 Quad core PC. Kernel compile time is 15 mins.

-Copy config from the Raspberry Pi to the Ubuntu box using SCP. Replace "raspberrypi" below with the IP address of your Raspberry Pi if hostname lookup fails.

If you are planning on displaying the console on the TFT, then enabling these options in .config will allow you to change the font size and rotate the display later on.

To enable parallel processing for a faster compile. If you have a dual core processor add -j 3 to the end of the command below. If you have quad core, add -j 6

The last step below is to SCP the files from from Ubuntu to the Raspberry Pi. If you have trouble SCPing into your Ubuntu box you may need to install open SSH on Ubuntu with sudo apt-get install openssh-server. This step also copies the files from my home folder "mark"... yours would be different.

If you build the st7735 driver pair as built-in, add these options to the end of the line in /boot/cmdline.txt. This will display the console on the TFT.

A wide variety of tft display 1.8 options are available to you, You can also choose from original manufacturer, odm and agency tft display 1.8,As well as from tft, ips, and standard.

This ST7735S 1.8" TFT Display features a resolution of 128×160 and SPI (4-wire) communication. Integrated with an SD card slot, it allows you to easily read full-color bitmaps from the SD card.

The module provides users with two wiring methods: pin header wiring and GDI (General Display interface). You can directly connect the display to a FireBeetle main controller using an FPC cable. Plug and play, easy to wire. Besides, the display supports a low refresh rate and offers a good display effect and strong versatility.
