The PIC16C781 and PIC16C782 are the first devices in a new line of mixed analog/digital microcontrollers from Microchip. These microcontrollers are a marriage of our traditional microcontroller architecture with new mixed signal peripherals that change many of the old conventions of embedded microcontroller design. Not only do the new peripherals open up new applications for the microcontroller...

There’s a broad field of applications for the microcontroller technology, that can be enumerated from simple, like small electric equipment operation, until sophisticated, like single loop digital controllers with man-machine and machine-machine interface, also using complex digital control techniques. The main preoccupation for us is to transmit to an undergraduate student, who hadn’t had any ...

Wireless Sensor Networks research and demand are now in full expansion, since people came to understand these are the key to a large number of issues in industry, commerce, home automation, healthcare, agriculture and environment, monitoring, public safety etc. One of the most challenging research problems in sensor networks research is power awareness and power-saving techniques. In this maste...

In this paper, we propose the hardware implementation of involutional block ciphers with low energy cost for cryptographic algorithm to WSNs by FPGA implementation. Formerly, microcontroller based sensor nodes are designed like PIC microcontroller, AT Mega128 microcontroller, MSP430.But it have some drawbacks .1) High processing time2) It consumes large amount of energy3) It have less security4...

A magnetic resonance imaging (MRI) pulse programmer has been developed using a single-chip microcontroller (ADmicroC7026). The microcontroller includes all the components required for the MRI pulse programmer: a 32-bit RISC CPU core, 62 kbytes of flash memory, 8 kbytes of SRAM, two 32-bit timers, four 12-bit DA converters, and 40 bits of general purpose I/O. An evaluation board for the microcon...

A microcontroller based capacitance meter using 89C52 microcontroller for the measurement of capacitance has been design and developed. It is based on the principle of charging and discharging of the capacitor. Atmel’s AT89C52 microcontroller is used in the present study. Further, an LCD module is interfaced with the microcontroller in 4-bit mode, which reduces the hardware complexity. Software...

This paper presents the design and development of a motion control system using a MEMS Accelerometer and RF communication with Atemga16 microcontroller. The accelerometer sensor can detect the tilt in all three axes and accordingly generate a corresponding analog output voltage. The generated analog output is converted into 10 bit digital output which is compared to the reference voltage mentio...
