The PIC can control the motor after every beat or its possible to bypass some beats. It can be done by pushbuttons. Rotation speed and rotation length can be adjusted too. Settings are limited between values to prevent possible register overflow-underflow.....

The Slave Flash Trigger is switched on/off by pressing the push button. When switched on, one to three flickers of the indicator lamp signalizes the programmed mode. One flicker determines that the flash will be fired at each flash. Two flickers indicate....

A prescaler attached to a PIC to get a simple frequency counter. I would suspect that it would just become a "module" that I include in some other design projects later. Initially I need to get a working sample. Target range would be 1mhz through 400mhz...

This simple programmer will accept any device that`s supported by software. The circuit is based in part on the ISP header described in the SILICON CHIP "PIC Testbed" project but also features an external programming voltage supply for laptops and for other....

It is all very well knowing how to program the PIC in theory, but the real learning comes when you try your code on a PIC and see the results yourself in a circuit. You could build a circuit each time and program the PIC to see if the program works, or you....

If you need more sensitivity, use 74AC04 or 74HC04 instead of 74HCU04 as U1. It may be better than 74HCU04, but the frequency response of 74HC04 may be worse...

The second program just sends "Hello world" to the PC. By default my board uses the Virtual COM Port (VCP) driver so you can view the output using Hyperterminal or similar program, I recommend PuTTY. The setup is quite simple, when I plug the PCB into my PC,....

The programmer uses serial signaling scheme to program the chip in circuit. The signaling is carried through the programming clock (PGC or ICSPCLK) and the programming data (PGD or ICSPDAT) pins. In addition, the MCLR/VPP pin is used as either a high voltage....

Communication with the MCP3028 ADC chip is done using a simple serial interface compatible with the SPI protocol. The Pic16f84 or Pic16f628 didn`t had hardware SPI peripheral. However, software implemeted SPI protocol can be done to communicate with 12 bit....
