Function design of the world line rate of change detector
3.1 World Line Mode
The world line rate of change detector, as the name suggests, is definitely the main function of displaying the world line. In order to increase the gameplay of the world line, I added a lot of fun features. Such as sensor buttons, wireless remote control, gravitational acceleration mode, custom world line display and so on. In particular, which sensor button can be said to inject the soul into the world line rate of change detector. In the world line made by others in the past, almost all of the above components were decorations, but Sadudu added very interesting interactive functions to the buttons, which is very fun.
1. Randomly display the world line mode
In this mode, the world line rate of change detector will jump randomly until it displays a fixed number, which can be achieved by three methods:
Touch the capacitor on the top of the world line: In time mode, touch the world line rate of change detector once to quickly switch to the world line rate of change mode. In this mode, long press will keep beating randomly, and a random display will be displayed when you loose it. World line. Double-clicking will return to time mode.
Wireless remote control button: In time mode, press the A button of the wireless remote control to quickly switch to the world line rate of change mode. In this mode, long press the C button and the world line rate of change detector keeps beating randomly, and a random world line is displayed when you loosen it.
WeChat control: There is a large random world line display button on the WeChat interface. Click once on the world line rate of change detector to keep beating randomly, and press it again to display a random world line.
This mode can be entered in the world line mode by pressing the B button of the remote control, or it can be switched by the WeChat client.
2. Gravity acceleration sensing world line mode
In this mode, the world line rate of change detector can sense its own position change, and will display the corresponding world line according to its own position:
3. Customize the world line mode
In this mode, the world line rate of change detector can display custom world line values, up to 8 groups can be set, which can be modified in WeChat.
By the way, the custom world line does not have to be a world line, it can also be 521.1314 (show whether there is an artifact), 233....., 3.1415926 (yes, the pi can also be displayed), 6.666666 and so on.
(You can define the value of the world line in advance when sending the girl, one 521.1314, one 19970327, and then suddenly press the remote control behind the back (the remote control is wireless, you don’t need to face the world line operation, you can put your hand in your pocket ) Switch to 521.1314, and display the girl’s birthday, such as 19970327, which will surprise the girl (in-person experiment)). . . The classmates who want to give gifts can only help you get here. . .
3.2 Time mode
In time mode, the world line rate of change detector can display hours, minutes and seconds. There are five display modes in the time mode, which can be switched in the WeChat applet. The details will not be introduced in detail.
You may ask, how does the world line adjust the time?
Sadudu: No need to adjust. Yes, yes, no need to adjust.
The world line rate of change detector can automatically synchronize the time, each time you connect to the phone, it will automatically get the phone time and automatically update, the world line time is synchronized with your phone time, and the phone time is synchronized with the network time Yes, so no matter where you are in the world, you don’t have to worry about the time difference. And in order to facilitate the usage habits of different countries, the 12-hour/24 switch can be modified in WeChat.
The world line rate of change detector has a high-precision clock module inside, with an annual error of up to 2 minutes, plus Sadudu's unique automatic update time mechanism, so there is no need to worry about time inaccuracies.
3.3 AT command mode
This mode is a ROM customized to meet the needs of advanced players. In this mode, the world line rate of change detector can be controlled by external devices such as Raspberry Pi, Arduino, and laptop.
To turn on the AT command mode, first insert the serial cable into the back of the world line rate of change detector, then connect the GND to the GND of the host (such as Raspberry Pi), the TX line to the RX of the host, and the RX line to the TX of the host .
The communication baud rate defaults to 115200, if you need a special baud rate, you can contact me to modify it.
The steps to enable AT command control are as follows:
Send "AT+ONRN" to turn on AT mode;
Send "AT+DIS=XxxxxxxxyyyyyyyyRN", X is the number to be displayed by 8 glow tubes, Y is the decimal point of 8 glow tubes, and the range of X is "0, 1, 2, 3, 4, 5,6,7,8,9,-", Y can have four values, namely "L, R,:,-" (case sensitive), "L" represents the decimal point on the left of the glow tube, " "R" represents the decimal point on the right side of the glow tube, and ":" means that the two decimal points of the glow tube are displayed at the same time. For example, if you want the world line rate of change detector to display 521.1314, you can send the command "AT+DIS=521-1314—R—-".
Send AT+TIME?RN, the world line rate of change detector will return the current time, such as TIME=20190612131456RN, which means the time is 12:13:56 on June 12, 2019, and the time format is 24-hour clock.
Send AT+TIME=20190612131456RN to set the time of the world line rate of change detector to 12:13:56 on June 12, 2019.
If you need to turn off the AT module, please send "AT+OFFRN" to turn off the AT mode.
The world line rate of change detector comes with two 3400mAh lithium batteries, which can guarantee 8 hours;
Comes with a wireless remote control, which can remotely switch the display mode, display the specified number, and randomly display the world line. This remote control is not an infrared remote control. You don’t need to face the world line rate of change detector and put it in your pocket. The remote control is at least 20 meters away from the open field, and it has not been tested. It is definitely a Cosplay artifact.
The world line rate of change detector can sense the finger. When the finger is placed on it, the world line will be displayed randomly, and it will keep beating when you keep pressing it until you release the finger to display a random world line value. Double-click to return to the clock mode.
The world line rate of change detector has a built-in three-axis accelerometer, which can switch the gravity sensing mode through the remote control, and the value of the world line changes with the position of the instrument;
The world line rate of change detector has Bluetooth inside, you can set a custom world line, special numbers, etc. through WeChat, such as 521.1314, 0.337587, 233... etc. After setting it up, you can remotely switch through the remote control
