One more point to note here is the exception number. The exception number is used by ARM Cortex M CPU to index into the location of the interrupt vector table. The vector table and interrupt service routines/exception handlers are defined inside the startup file of a microcontroller. The star...
“It’s going to be a game-changer for Qantas” enthuses CEO Vanessa Hudson, "with a new customer experience, new seats, WiFi, bigger overhead compartments for baggage and much larger windows so the cabin environment is much better” than the 717. The modern A220 will replace the ageing B...

In this circuit, the 555 timer circuit constitutes a voltage-controlled oscillator. The control terminal cooperates with the field effect tube to realize the large-scale adjustment of the duty cycle. The circuit is shown in the figure: In the circuit, the 555 timer, resistors R1, R2, capacito...
A substitution, based on an electrical port, is now supported when that substitution is requested inside the #BEGIN/#ENDBEGIN directive block (#6332). Polygraph hotkeys (ex. ‘y’) now function properly (#6577). Virtual wires will now properly identify and display feedback loop signals (#...
Inside a Microcontroller As we explained above, a microcontroller is embedded with different elements like CPU, RAM, ROM etc. CPU CPU is analogous to processor in a computer, which basically consists of Arithmetical and Logical Unit (ALU), Control Unit and Register Array. As the name indicates...
What is PWM (Pulse Width Modulation)? PWM stands for Pulse Width Modulation; we will get into the reason for such a name later. But, for now understand PWM as a type of signal which can be produced from a digital IC such as microcontroller or 555 timer. The signal thus produced will ...

I am using a Esky transmitter, and i was wondering what the difference is between the Transmitter and receiver crystals since they appear to be different. What are the real values of the crystals and is there a cheap DIY hack to replace crystals with for instance 555 timer circuits? Sign...
Aside from the technical definition of SNR, the way I define it in other terms is by using a comparative. For example, say that you and one other person are inside a large room having a conversation. However, the room is full of other people who are also having conversations....
