Basic USB-RS232 Communication by PIC Microcontroller
Monday, February 15th, 2010





The quickest way to display something is probably sending the data to the computer to be displayed on the monitor. One of the ways to do this is to use the USART module on board the PIC Microcontroller by making use of the pins RC6 and RC7 which is also the TX and RX pins [...]

JDM Programmer Modification by COM1
Friday, August 14th, 2009





The JDM (or Ludipipo) seems to be among the most popular PIC programmers used - and rightly so: it is simple, cheap and easy to build, can be run with the free and excellent IC Prog software by Bonny Gijzen, and will program pretty much any PIC microcontroller on the market. However, an issue has [...]

Driving Bipolar Stepper Motors by PIC16F84
Stepper motors are devices, which convert electrical impulses into discrete mechanical rotational movements. In a typical stepper motor, power is applied to two coils. Two stator cups formed around each of these coils, with pole pairs mechanically offset by ½ a pole pitch, become alternately energized North and South magnetic [...]
