One of the first things I like to do when creating a new project is to get the I/O working. This helps in debugging the code as I write it. What about projects that do not have I/O? This device sneeks both input and output from your computer (terminal program) to the PIC using just […]

I’ve had good cause to be reading and perusing a few old Circuit Cellar articles every day for the past several weeks. We’re preparing the upcoming 25th anniversary issue of Circuit Cellar, and part of the process is reviewing the company’s archives back to the first issue. As I read through Circuit Cellar 143 (2002)

This project uses one of the smallest chips in the PIC microcontroller range, the PIC12F629 and you can learn to program it and experience the thrill of making something yourself and see what goes into writing a program. Even a program as simple as this one is not easy to put together and if you
This design controls up to 8 devices using a PIC microcontroller (PIC16F84A) connected to the phone line. The unique feature here is that unlike other telephone line based remote control, this device does not need the call to be answered at the remote end so the call will not be charged. This device depends on

Overview Matlab has a “serial” function that allows it to communicate through a serial port. This project is to establish serial port connection with the PIC microcontroller and demonstrate bidirectional communication between the PIC and a Matlab program. For demonstration purposes, the PIC will send digital potentiometer readings to Matlab as well as receive keystrokes

Description This project combines a GPS receiver module, a MicrochipPIC microcontroller and a Secure Digital memory card to make a GPS data logger. With a large capacity and reasonably long battery life it is a very useful device for logging GPS position for example for mapping with OpenStreetMap. In this picture the complete GPS data

This post provides the software UART (Bit Banging) code for PIC12F675 microcontroller (e-g to connect PIC controller with PC using serial adapter). As we know, PIC12F675 microcontroller doesn’t have built in UART module, so we can create UART functionality in it’s software. This post provides the details of how to program software UART functionality in PIC12F675. This

On this page I hope to provide more details than I usually provide for those who wish to construct their own PIC-bot, realising that people actually try to make this stuff. Traditionally, my ‘bot pages are for documenting the essentials, not in the kind of detail needed to make as if it were a kit.
These days I was thinking about a better PIC programmer that can work with MicrochipMPLAB IDE software so that I can write my own programs or edit someone else’s programs. I found that there are numerous versions of the famous Microchip PICkit 2 on the web. Some of them are using the original schematic published
Features Fits in one half height 5.25″ drive bay. Back light 16 x 2 lines LCD (Hitachi Compatible) display. 4 Selection buttons, arranged so that it looks like an ATM machine. RS232 19,200 baud connection to PC with Hardware handshaking (CTS). Uses a subset of the standard VT-52 control codes to control the LCD. 3.6864MHz
