we will define the interrupt vector table (IVT). Secondly, we will see the role of IVT for interrupts and exceptions processing in microcontrollers or microprocessors. After that, we will see the interrupt vector table of TM4C123G ARM Cortex M4 microcontroller. ...
An ISR is present for every interrupt. The address of each ISR is stored in a fixed location in memory. An ISR can call for asynchronous interrupts and handle both maskable and non-maskable interrupts. When an interrupt occurs, the microcontroller runs the ISR. At the start of execution, th...
A microcontroller is a sophisticated single-chip microcomputer that integrates all essential computing elements onto a single integrated circuit (IC)...
Firstly, the startup file of TM4C123G microcontroller defines the stack area section and stack size in RAM memory. In this line, EQU is a assembler directive and it works similar to #define directive of c language. This line define a constant named “Stack_Size” with the value of 0x00...
Analog to Digital Converter & Digital to Analog Converter:These are the convertor used inside the microcontroller in order to convert the signal fromanalog to digitaland vice versa. Interrupt control:The name itself is self explanatory and it helps to perform the program without any interruption. ...
What is PWM in microcontroller? Pulse Width Modulation(PWM) is a technique where the width of digital pulses is adjusted to generate different average dc voltages. Most microcontrollers have a built-in timer that can be used to generate a PWM signal. ...
The biggest difference between the two is PLC can perform discrete and continuous functions in a harsh environment which a PC cannot do. You can also read difference between PLC and microcontroller to get an overview of its comparision with microcontrollers. There are many different types of PLC ...
effect of calling into the memory allocator’s compartment), registers never hold stale pointers. This, in turn, means that we don’t need to do checks on data loads and stores (though we would have to either do this or explicitly serialize cores on free for a multicore microcontroller)....
A recent trend, started by ST in Industrial AI, is the ability to run a machine learning algorithm within a sensor instead of using a microcontroller. The first device to provide this capability commercially was theLSM6DSOX, launched in 2018. The sensor we saw today in the Proteus industrial...
The other half of the switch is a bit cunning. At first sight, it looks like it won’t do anything much: it grounds the base of the transistor in both positions, so why is it even there? The answer is a subtle: for an instant while the switch is between positions, that connection...
