AOverviewThe Digilent Pmod MTDS (Revision A) is a gorgeous 2.8” touchscreen display with a powerful on-board microcontroller that performs graphics processing tasks. The display is a capacitive touchscreen with QVGA resolution (320×240) and 2 finger multi-touch support.Features include:∙ 2.8” Display with QVGA resolution (320×240)∙ 2 Finger Capacitive touch panel∙Powerful PIC32MZ Microcontroller∙Multi-Touch Display System (MTDS) Firmware∙Design a beautiful UI with only a few lines of codeusing libraries for Arduino IDE and Xilinx SDK∙Follows the Digilent Pmod Interface Specification1.0, Type 2A (Expanded SPI)The Pmod MTDS.The most compelling aspect of the Pmod MTDS is the programming experience provided by its Multi-Touch Display System (MTDS) Firmware and the associated libraries. These allow you to design sleek, stylish user interfaces very quickly and with very little code. The timing dependent tasks are handled by the firmware, so integrating the display into existing projects is also a snap. Some of the key functionality provided by the libraries include the ability to draw basic shapes and text, draw images stored on microSD with binary transparency, draw buttons and easily check if they have been pressed, and check the status and location of the user's two fingers. The libraries are supported in Arduino IDE and Xilinx SDK, and have been tested with Ardiuno, chipKIT and Arty host boards.1 SpecificationsParameter Min Typical Max UnitsPmod Power Supply Voltage (VCC) 2.2* 3.3 5.5 VOptional External Power Supply Voltage (VEXT) 2.7 5.0 6 VTable 1.

Jumpers.1.2 Physical DimensionsThe pins on the pin header are spaced 100 mil apart. The PCB is 3.45 inches long on the sides parallel to the pins on the pin header and 2.00 inches long on the sides perpendicular to the pin header.2 Functional DescriptionThe Pmod MTDS has an on-board PIC32MZ microncontroller that is running the MTDS firmware. To communicate with the device, you must use the MTDS and MyDisp libraries available and documented on the MTDS resource center. Arduino and chipKIT host boards should use the Arduino IDE libraries, and Xilinx FPGA or Zynq based hostboards should use the Pmod MTDS IP core and the libraries included with it. For information on downloading and using the Pmod MTDS IP core see the Using Pmod IPs Tutorial. After exporting to Xilinx SDK, follow the README.txt guide included in the examples folder.JP1 is used to select how to power the display's backlight. A single jumper should be loaded across 2 of the three pins in order to select the power source. When the jumper is loaded across the bottom 2 pins the backlight is powered by VCC on the Pmod connector, and when it is loaded across the top two pins the backlight is powered by an external power supply attached to J2. This external power supply must meet the minimum and maximum voltage requirements outlined in the Specifications table above.The microSD connector allows the MTDS firmware to draw and save images to an attached microSD card. In order to work properly, the microSD card must be formatted as FAT32. Image files should be saved as Windows Bitmap files (.bmp). For more information see the MTDS documentation available on the MTDS resource center.2.1 Serial CommunicationThe Pmod MTDS communicates with the host board via the SPI protocol; however, the implementation of this physical interface is handled by the MTDS libraries and it is not necessary to understand the details for its use.2.2 Quick UsageTo get started with the Pmod MTDS quickly, go to the MTDS resource center and follow the instructions found there for your host platform.。

平民级超跑上手游戏悍将AS27 UC-PRO电竞显示器作者：来源：《新潮电子》2020年第03期相信經常关注电竟显示器的玩家对圈内流传的“四大金刚”并不陌生。

就算不清楚也有所耳闻。

所谓“四大金刚”其实是指显示器的硬件参数：工44HZ及以上的刷新率、2.5K分辨率、G-SYNC技术、IPS面板。

在当时又正好有四款产品具备这样的参数要求。

分別是华硕PG279Q、AOCAG271QG、掠夺者XB271HUbmiprZ、优派XG2703-Gs。

这样“四大金刚”就开始流传开来。

以现在来看。

这些参数虽然已经算不上顶级。

但是也并不落伍。

不过取而代之的是更高端的4K@144HZ电竟显示器。

在2018年。

具备4K@144HZ的电竞显示器还只有ROG PG27UQ和ACER X27两款代表产品。

价格更是高高在上。

近两万元的售价着实不便宜。

堪称电竟显示器中的“超跑”。

时隔一年。

由于生产成本的逐渐下降。

4K@144HZ的电竟显示器开始多了起来。

像我们本期体验的游戏悍将AS27UC-PRO就是其中之一。

可以说是平民级“超跑”。

相信很多朋友跟我一样，对游戏悍将的印象还停留在机箱、电源产品线上、游戏悍将涉足显示器领域的时间的确不长。

这款AS27UC-PRO是旗下首款27英寸4K电竞显示器。

同时也是旗下的一款高端电竞显示器。

对于这款显示器，相信游戏悍将对它寄予了很大的期望。

那么实际表现如何？我们将对它的里里外外进行全面的解析、点竞化的外观设计既然定位于电竞显示器，那么在外观上就要给入电竞的气息、游戏悍将A$27UC-PRO的整体外观设计采用了黑色的外观，在底座上、支架提手上辅以红色进行点缀。

这种红黑式的配色，似乎有一种战斗的味道、AS27UC-PRO的整体设计看上去比较清爽、千练，不像其他电竞显示器有激进的设计感。

AS27UC-PRO采用的是人体工学支架，支架支持上下升降和旋转调节。

帮助玩家找到最适合自己的姿勢、同时。

AS27UC-PRO也支持用户安装第三方支架，孔位规格为75mmx75mm。
