报告里显示得那么强劲。苹果不得不宣布iPhone X第一季度产量，由此前预估的4000万台减少至2000万台，订单几乎呈腰斩之势。如此局面首先会影响到苹果的利润，毕竟，iPhone X销售会减半，可他们依旧统治着智能手机市场，占据整个市场利润的83%左右，苹果的股价偶有波动，但始终是一个“财务健康”的公司。相比之下，他的供应商们就没有如此幸运了，他们正准备迎接新一轮的春天，却遭遇了延长的寒冬，幸存者真要好好思考未来的模式了。Why sales are weak because of the high hopes of exploding iphone X?The IPhone X's quarterly order was cut from 40 million units to 20 million units, an earthquake-style message. So that more and more people feel that the global economic crisis is coming. Obviously, such a harsh state i

Load i2c-bcm2708 and rtc-ds1307:sudo modprode i2c-bcm2708sudo modprobe rtc-ds1307After the I²c configuration is complete, if it is the model B of Raspberry Pi, then in the terminal input:sudo i2cdetect–y 1Of course, if it is model A of Raspberry Pi, then enter:sudo i2cdetect–y 0At this point, you can see the output information: Next, add the obtained RTC hardware address information to the I²C device and enter it at the termin

by Adam TaylorStarting last week's blog, we have entered the programming of the OLED display module on the Zedboard (instead of the microzed) board. Before formally entering the specific OLED program, however, I think it is necessary to verify that we have configured the SPI port correctly for the application. This action can be a lot less time for our next steps, and it's easy to do. In fact, it's really s

the 5V pin of the Raspberry Pi, but you need to configure I²C before using RTC. 1. First install the Linux i²c driver module:sudo aptitude install i2c-tools Libi2c-dev2. Load i2c-bcm2708 and rtc-ds1307:sudo modprode i2c-bcm2708sudo modprobe rtc-ds1307After the I²c configuration is complete, if it is the model B of Raspberry Pi, then in the terminal input:sudo i2cdetect–y 1Of course, if it is model A of Raspberry Pi, then enter:sudo i2cdetect–y 0At this point, you can see the output information:

) LCD application field: TV, computer display, mobile phone display, industrial display, etc.(5) The history of LCD (TN/STN/TFT)TN earliest. The disadvantage is that the response is not good enough, there is the phenomenon of trailing.STN is an upgraded version of TN. Effectively solve the trailing phenomenon, display clearer.The biggest feature of TFT is ultra-thin. TFT technology developed a lot of newer technology.2, other mainstream display equipment (LED, CRT, Plasma,

medium size panel growth highlights in the wearable device, virtual display and car display, demand will appear differentiated, more flowering. Small and medium-sized panels are the technical route to the world, the consumer market is more willing to pay a higher premium to the obvious technical advantages of the screen. The current mainstream of four technical routes include: A-si (amorphous silicon), LTPS (Low-temperature polycrystalline silicon), IGZO (oxide),

liquid crystal displays (Liquid crystal display LCD) and organic electroluminescent diodes (organic light emitting diodes OLED) "Note 1"The display typically has a 60Hz frame rate. The refresh from the display starts at a corner, after which the message is transmitted one line at a point until all the displays are refreshed.An illustration of the scanning direction of a displayThere are two different types of display driver ICS, with internal RAM and

Top Ten innovations in China's information technology field: 1. OLED The OLED technology and Plasma Display Technology (PDP) and Field Emission Display Technology (FED) are listed as three directions of display technology. With the advantages that enable self-illumination without backlight, The OLED will be widely used in the future. Currently, PDP Technology

Apple today officially released a new generation of 13, 15-inch MacBook Pro, and the most eye-catching change is naturally the use of an OLED screen to replace the previous F1-F12 function keys. Apple calls it touch Bar, which automatically switches to its corresponding accelerator panel for changes in application, with more flexibility. However, the use of OLED touch screen instead of the Entity function

Multilayer data structures estimate that all web developers are not unfamiliar, and the classification of various software is based on multi-layered structure.The following is a typical multilayer data structure:Related CREATE DATA statement:CREATE TABLE Category (category_id INT auto_increment PRIMARY KEY,Name VARCHAR () is not NULL,Parent INT DEFAULT NULL);INSERT into categoryVALUES (1, ' ELECTRONICS ', NULL), (2, ' televisions ', 1), (3, ' TUBE ',

The day before yesterday when playing OLED want to finish always want to make a thing, is simple single-chip computer game. Because the memory of STM32 and nRF51822 is sufficient, the image is displayed using the cached array method (I don't know what the term is, anyway, it's a two-dimensional array of 128x64 in memory, which refreshes the entire array on the screen when the display is updated). And the two OLED
