John: There're 2 pictures above. They are the circuit of inverter. . Me: OK. . John: Which one is correct? Me: Logically, the 1st picture is correct. John: Why? Me: I show it to you in code. John: OK. . If (input side = Up cycle) { NPN = UP cycle and NPN = saturated. PNP = UP cycle and PNP = cut off. The output = 0. } . John: You're wrong. The 2nd picture is correct also. Me: Why? John: I show it to you in code. Me: OK. . If ( input side = Up cycle ) { NPN = Up cycle and NPN = saturated. PNP = Down cycle and PNP = saturated. The output = 1 or 0 } . Me: When the input side is Up cycle, the gate of PNP is down cycle? It is impossible. John: It is possible. Take a look at this article ( https://wodewangzhishime.blogspot.com/2022/03/httpswodewangzhishime_14.html ). . Me: OK. I assume that it is possible. T...

https://wodewangzhishime.blogspot.com/2022/06/satellite-for-loop.html . Ref: https://wodewangzhishime.blogspot.com/2022/05/httpswodewangzhishime_18.html . . . There're 5 conditions on which left or right shift doesn't work. . 1) The latch is being preset and clear. 2) The latch is feedbacking. 3) The latch is being level-trigger. 4) The flip flops is at the stage of toggling. 5) The commutator is idle (no up , no down) . This picture is just my own design. . If the commutator is at 1, NPN is saturated,right shift is available. . If the commutator is at 0, PNP is saturated,left shift is available. . Me: Now, we mention condition_4. . The commutator is idle. . No Up cycle. . No Down cycle. . John: In this case, no right shift. . No left shift.

Me: I instantly quote an example. . .We have a code of MOV R4, R1. .  . Inside the the Register of R4, there're 6 fields. 1) Subject [R1] 2) Role [Master] 3) Interrupt Status [system clock line] 4) Type of value [Words] <--- First round. . R1 will Check if the type of value is words. 5) Object [R4] <---- First round. .R1 will  Check if there is a register called R4 in the cache. 6) Value [0101.1000] === There is a vector table next to the modulator. . . This table is cache. Inside the cache, there're 6 fields. . 1)  Subject [R4] <------ First round checking, pass. 2) Role [pending] 3) Interrupt status [pending] 4) Value type [Words] - - First round checking, pass 5) Object [pending] 6) value[pending] <--- Second round. Set the value . Me: If the first round checking doesn't pass, there ...

Me: The "black dot" indicate the direction of the flow of the current. . In the upper picture, circuit A and B have same direction of the flow of the current . As a result, the resistance of both circuit is high. John: But, in the lower picture, circuit A and circuit B have different direction of the flow of the current. . As a result, the resistance of both circuit is low. . If (direction of current flow = same) {  resistance of the circuit = high; }   else if (direction of current flow = different) {  resistance of the circuit = low; }

John: There're many type of communication's protocol . You might have a look .  https://instrumentationblog.com/communication-protocols/ .  Me: Yes,. John: For example, RJ45, I2C, USB, SPI, RS232, so on and on. Me: OK. John: Before we start, you should read the 3 articles below. Me: OK. . 1)  https://wodewangzhishime.blogspot.com/2022/02/httpswodewangzhishime_80.html 2)  https://wodewangzhishime.blogspot.com/2022/02/httpswodewangzhishime_26.html 3)  https://kamchihau.blogspot.com/2022/11/impact.html . John: We use the protocol of SPI as an example. Me: OK. John: Look at the picture above. Me: OK. John: The slave use the clock line of the master. Me: OK. John: Normally, the master choose the clock line of SPI. Because, it is a protocol of SPI. . Me: OK. . John: However, hacker hack it. It Become, . ...

John: Before we start, you may read this article ( https://wodewangzhishime.blogspot.com/2021/11/httpswodewangzhishime_77.html ). This articles is about chosen line of power source. Me: OK. John: After that, you may read those 3 articles below. Me: OK. . 1) https://wodewangzhishime.blogspot.com/2022/02/httpswodewangzhishime_80.html 2) https://wodewangzhishime.blogspot.com/2022/02/httpswodewangzhishime_26.html 3) https://kamchihau.blogspot.com/2022/11/impact.html . John: Now we start. Me: OK. John: I assume that there is a general register. This register choose 010. What sort of line is 010? Me: It may be a clock line . It may be a line of power source. John: How do you distinguish between them? . 1) If it is a line of power source, the direction of current flow is unilateral.  2) If it is a clock line, the direct...

sequential (44) no realistic serial circuit (the current lead the voltage)

Ref: https://wodewangzhishime.blogspot.com/2022/03/httpswodewangzhishime_1.html  . . . . . 1) In a capacitor, the current lead the voltage 2) In an inductor, the voltage lead the current. . . John: See this article first. ( https://kamchihau.blogspot.com/2024/07/sequential-109.html ) .  Me: OK. . John: This article ( https://wodewangzhishime.blogspot.com/2021/12/httpswodewangzhishime_28.html ) mention about how dangerous the carrier wave is. . Me: This article ( https://wodewangzhishime.blogspot.com/2022/03/httpswodewangzhishime_14.html ) mention about that if R0(1) is unstable and become a gap, a new register may appear. . John: However, carrier wave is high frequency. Normally, the carrier wave will be discarded. Look at the 1st picture. There is a capacitor. The wave of high frequency go through the capacitor and then enter the ground. Only the message wave is left. The message wave is low f...

John: This article ( https://wodewangzhishime.blogspot.com/2024/02/httpswodewangzhishime.html ) mention about that there isn't any realistic serial circuit in the monde.  OK. We start this article. There're 2 pictures  above. Which picture is logical ? . Me: The "upper" picture is logical. Because, point A and point B are on the Up cycle. The "lower" picture is illogical. Because, point A is on the Up cycle, Point B is on the down  cycle. . John: You're wrong. Both picture is logical.

Not all the chips have the Left/Right shift line. Left/Right shift line is a field. . For (int i = 0; i<100; i++) { Sum = Sum + i (Right shift) Receiving.  } . __ . For (int i = 100; i>0; i--) { Decrease = decrease - i (Left shift) Sending.  } Subject [I2C] Object [Sum] Interrupt_status [ ] Load_Shift_status [Shift] Left_Right_Shift [ right ] <-- Right shift mean receiving. In the port of SPI, you're not supposed to set it. . Me: The port of I2C is only one line. This one line is used for both receiving and sending. Therefore,  Left/Right Shift line is needed in this case. . John : Other chips doesn't have Left/Right Shift line. . Me: Right shift mean receiving in the port of I2C.  Left shift mean sending in the port of I2C. . John : Spi port has 2 line. One is for receiving.  On...

John: 2014, Miuson ask Kelvin to use the poison to kill my father in the hospital. Guess what happen ? . . Kelvin : You provoke John . Mary (the public relation of the hospital): How do I provoke him ? Kelvin: You give a phone-call to John. You pretend to feel pity and pretend to sob and say to John, " Your father is miserable. ". ____________________ Bradley: Kill those students, e.g., Mary. Kelvin : Hey ! It's me who killed John's father not her. Bradley : I don't care. Kill her. Kelvin : Please. ___ Miuson : You told Bradley that It's you who kill John's father not Mary.  Kelvin : If I don't say that, Bradley gonna kill her. Miuson look at the sky and take a deep sigh,...
