Interfacing 7-Segment Display with PIC Microcontroller Introduction A seven-segment display can be used to generate a number from 0 to 9, it consists of 7 bar-like LEDs arranged in the shape of the number 8, and another dot-shaped LED at the bottom right. These LEDs are identified clockwise from the top as letters from a …

Interfacing LED with PIC Microcontroller Now that we have studied various things about the PIC microcontroller, it is time to apply those concepts in some projects. So this article would explain about interfacing LED with PIC Microcontroller, Instead of using a physical microcontroller, we will be simulating it quickly, once you have completed a simulation, …
ADC | Analog to Digital Converter ADC full form is analog to digital converter. Also read about ramp wave generator circuit in this blog. Physical sensors measuring natural phenomenon are all analog in nature. They are continuously variable and can take an infinite range of different values, whether we are talking about temperature, sound level, …
Interrupts in PIC Microcontroller Interrupts are special events that when taken place, need to be handled right away. In case of a CPU which is deeply ordered, this was applied to allow emergency external events to get the attention of the CPU, emergencies like power failure, the system overheating or major failure of a subsystem …
Communication Protocols | PIC Microcontroller A PIC microcontroller system has many peripherals connected and an essential activity of these systems to work properly is to effectively transfer data between the microcontroller and the various peripherals. Broadly speaking, there are two ways of transferring the data. In parallel transfer, all the bits of the word are …
Registers in PIC Microcontroller PIC Microcontrollers use registers for storage. They store the data that is going to be used, they store the instructions that are to be used and they store the results obtained. Registers are made up of using a number of flip-flops. Each flip-flop can only store one bit so to handle …
PIC 16f877a Memory organization We look into the memory organization of the PIC microcontroller in this blog post. We do this to determine the microcontroller unit(MCU) efficiency on whether it is capable of retrieving the instruction and data in one cycle and to find the size and limitation of each memory area. PIC microcontroller consists …
ARM 7 Instruction set Learn about arm 7 instruction set, Conditional Branch Instructions. Compared to other RISC microcontrollers, almost all ARM 7 core instructions are conditionally executed. As conditional branches are standard instructions, ARM 7 instructions were extended by adding 4 bits at the top of the 32-bit instruction field. CLICK HERE to access complete …
Addressing Modes in ARM The phrase addressing modes in ARM relates to the manner an instruction operand is expressed. Before the operand is actually performed, the addressing mode provides a rule for interpreting or altering the address field of the instruction. Also read about data processing instructions in arm, Register indirect addressing mode, Register indirect …
ARM Interrupts In general, ARM Interrupts are signals from a computer device or a programme within a controller that prompts the main programme to halt and choose what to do next. When an interrupt occurs in ARM, the ISR (Interrupt Service Routine) is called. When an interrupt is received, a component of a programme takes …
