PICADC – a free, PIC based “intelligent” A/D converter using PIC16F84

This is an old design. Some of the components may be difficult to buy. If you would like to build an even better and cheaper A/D converter, take a look at the new PICADC3 design. The PICADC is a simple 12-bit, 8-channel analog to digital converter (with 4 additional digital inputs), which may be connected to the PC through the serial interface (RS232). The sequence of sampled channels, and sampling frequenc ...

USocket – USB controlled Socket with PIC18F4550

Introduction The idea of this project is to control (switch off/on) two power sockets with a computer by using its USB port. I’ve chosen USB in first place because I wanted to experiment with the PIC18F4550 microchip’s microcontroller, and secondly because the power supplied by this port (500mA) is enough to activate a relay without any additional power supply. The firmware is based in SIXCA USBDAQ which is ...

USB Interface Board Driver Installation PIC18F4550

USB Interface Board Driver Installation Connecting PIC18F4550 First Time This tutorial will try to explain how to make your interface development board to work for the first time. Without a Demo hex code inside PIC18F4550's flash memory, it  won’t respond even if we connect the Demo Interface Board Directly to computer. In my previous post we have successfully loaded the Demo Hex Code into the PIC18F4550  u ...

PIC’ing the MAX5581: Interfacing a PIC Microcontroller with the MAX5581 Fast-Settling DAC

MAX5581 Overview The MAX5581 is a 12-bit, fast-settling DAC featuring a 3-wire SPI™ serial interface. The MAX5581's interface can support SPI up to 20MHz with a maximum settling time of 3µs. This application note presents an application circuit and all the firmware required to interface the fastest line of PIC microcontrollers (PIC18F core) to the MAX5581 DAC. The example assembly program was written specif ...

Ways you can use the DDS Daughtercard

How many ways can you use a self-contained, high-precision signal source contained on a 1" x 2" plug-in circuit card? How about as a stand-alone VFO, a signal generator for your bench, a replacement LO for your Sierra or NC40 transceiver, or perhaps as the heart of an antenna analyzer! Control it with your favorite microcontroller, or even hang it off your PC's printer port. Any way you do it, you'll be gen ...

USB Voltmeter using pic microcontoller

USB Voltmeter USB Voltmeter is a PC based dual channel voltmeter built around PIC18F2455 / PIC18F2550 microcontroller that measures voltage from 0.00V up to 500.00V with 10mV resolution. USB Voltmeter sends measured data to PC via standard USB connection displaying data on a computer monitor. USB Voltmeter is self-powered drawing very little current from USB port. Voltage readings are displayed via included ...
