The TFT library provides the following Application Programming Interfaces(API). The library makes use of direct access to PORT registers instead of Arduino APIs. This is to increase the speed of communication between MCU and TFT. At present, the library supports Arduino, Arduino Mega (1280 or 2560) and Seeeduino ADK Main Board compatible boards. In Mega the 8bit data port of TFT is distributed to different pins belonging to different ports. This decreases the speed of graphics drawing when compared to Arduino. The choice of port pins are purely based on Arduino / Mega port pin arrangement.
TFT Touch Shield uses the Adafruit Touch Screen Library. In short, a 4-wire resistive touch screen provides two voltage divider each for X and Y axis. By applying proper voltages for each axis and scanning the ADC values the position of the touch can be detected. These values are always prone to noise. Hence a digital filter is used.

The 3 points is default not soldering at the factory. Arduino has a 2*3 pins with SPI interface, but pcDuino doesn’t have that SPI interface. When you soldered the 3 points, pcDuino will communicate Touch LCD Shield through GPIO 11, 12, 13.[/vc_column_text][/vc_tab][vc_tab title=”Test Code” tab_id=”1421631406833-2-5″][vc_column_text]This a part of the code, please download the complete code here:Code TFT_Touch_Shield
pcDuino is a mini PC or single board computer platform that runs PC like OS such as Ubuntu and Android ICS. It outputs screen to HDMI. Moreover, it has hardware headers interface compatible with Arduino (TM). pcDuino can be used to teach Python, C and more interesting stuff.
In this tutorial, we show the steps on how to flash LinkSprite Acadia, a single board computer that is powered by Freescale Quad-core i.MX6. Note: Right now, you need to do the following work on a Windows PC.
This is a 1.8 inch true color TFT LCD come with a TF card socket. It can work with Arduino Esplora board perfectly. You can run all the example codes that arduino IDE provided for Esplora TFT LCD.
This LCD module is 1024x600 dots 7 " color TFT LCD module display with HDMI-compatible, VGA, Video, AV signal driver board, superior display quality, and super wide view angle. It can be used in any embedded system, car, industrial device, security, and hand-held equipment which requires a display in high quality and colorful video. Its HDMI-compatible interface is fully compatible with Raspberry PI, Arduino, and Banana Pi platforms.

PLAY-ZONE is the official Swiss Distributor for LinkSprite/pcDuino
The pcDuino3B is identical to the pcDuino3, which launched last April, except for changing the 10/100Mbps Ethernet connection to gigabit Ethernet. The LinkSprite launch price is $60, down from an official price of $77. This is $10 more than the original model, which also started out at $77, but now goes for a low of $49 on CuteDigi. Meanwhile, earlier today CNXSoft found the new “B” model going for $50 on eBay, but they are disappearing fast.
The stripped down “Nano” version of the pcDuino3 lacks the pcDuino3/3B’s LVDS interface, I2S stereo digital audio output, and built-in WiFi. However, it adds a second USB 2.0 host port, and like the pcDuino3B, it moved from 10/100 to 10/100/1000 Ethernet. The board is also smaller, at 92.2 x 54.1mm.
Like the pcDuino3, the pcDuino3B offers a 1GHz, dual-core Allwinner A20 SoC with 1GB RAM and 4GB flash. As before, there’s also a microSD slot and a SATA interface. WiFi is once again available along with the upgraded gigabit Ethernet port.
The following specifications are listed by pcDuino.com for the pcDuino3B. These are also the specs for the pcDuino3, except for the move from Fast Ethernet to GbE:
The Raspberry Pi 2 is finally out front in price/performance ratio, but it still has some gaps in I/O and other features compared to most community boards. The pcDuino3B’s gigabit Ethernet feature leads a growing wish list of features craved by ARM SBC enthusiasts along with the already available SATA link, neither of which is available on the Pi 2. The first quad-core Raspberry Pi also lacks built-in WiFi, among other features, and has yet to announce Android support, despite supporting resource-hungry Ubuntu and Windows 10 builds.
The PCDuino3B is available for $60 plus shipping at the LinkSprite Store. More information may be found at the combined pcDuino3 and pcDuino3B product page.
I’m sure you’ve been reading a lot about the Arduino, Raspberry Pi, BeagleBone and the PCDuino boards. But you might still be wondering which one is for you.
I choose Raspberry Pi. It will do almost everything you need, is cheaper and more popular within the open source community. If you want something more powerful simply go with the BeagleBone or PCDuino. Any of these boards are a great choice!
