The project presented here is a dual AC to DC output linear power supply. This power supply provides low ripple low noise DC regulated output. Usually, transformer-based linear power supplies are considered very bulky and inefficient, but this power supply still is very important for sensitive applications such as analog circuits, communications devices, radio devices, […]

Make a hardware interface list Using a preliminary hardware block diagram, list all the external interfaces that the microcontroller needs to handle. Two common types of interfaces should be mentioned. The first is the communication interface. USB, I2C, SPI, and UART are commonly used peripherals in systems. If your application requires USB or Ethernet, add

Optionally, the mux (U2) has external, post-mux, pullup resistors (RP4 and RP5) to provide power for idle 1-Wire slaves when the switches are open. If this is not done, each time a channel switch is connected, the ”C must wait the maximum wake-up time of the connected slaves on that channel (usually 2ms) before beginning communication.

One very common thing in electronics is the need for two intelligent devices to communicate with each other. When you first see a PIC and Arduino you might think that they are two differeny systems and don’t share much in common, but you’d be wrong! In fact, the AVR and the PIC microcontrollers have many

PLC (Power Line Communication) is the technology that allows data transmission over the existing Power Line network. Power Line can be the home power network or the national electricity transmission grid. The data that can be transferred is as diverse as its speed. With speeds of nearly 200Mbps, video transmission, voice, data and any other services can be
