Prototype: Openbench Logic Sniffer logic analyzer using pic microcontoller
Openbench Logic Sniffer is an open source logic analyzer. It’s designed to support the SUMP logic analyzer software at the lowest possible cost. Download the source and design files from the Gadget Factory project page. This project started in the comments on a post. Initial circuit design, PCB layout, development, and testing continued in the […]
Logic Probe Plus using PIC12F683
This project is based on a probe logic states, capable of measuring levels from TTL (5v) to state levels of PLC’s (24v). For this we have employed the use of the PIC 12F683 microcontroller, which by its nature is capable of operating at low voltages, in this case 3vcc, besides having analog inputs and internal […]
Interfacing the Microchip PIC18F Microcontroller Master Synchronous Serial Port (MSSP) to various I2C Devices
The Inter-Integrated Circuit or I2C (read as I square C) bus has been introduced in 1980 by Philips, and has become a de-facto world standard for data exchange between Microcontroller and various devices such as temperature sensor, ADC (analog to digital converter), DAC (digital to analog converter), I/O expander, EEPROM, and many more. With more […]
H-Bridge Microchip PIC Microcontroller PWM Motor Controller
One of the advantages using the Microchip PIC microcontroller Pulse Width Modulation or PWM for short is; this PWM peripheral circuit is designed to control the DC motor using the full bridge mode PWM feature. The PWM peripheral works by supplying the correct signal to the H-Bridge DC motor circuit such as speed controlling and […]
LEDactus using PIC18F1320 Microcontroller
The LEDactus is my version of a dry climate niche dweller like a cactus. LEDactus is immobile and attempts to survive by creating a pleasant display. This is of course in the hopes that passersby will be so entranced that they will build the LEDactus’ progeny. Initial generations create a simple but pleasing display. Later […]
Controlling a Servo with a PICAXE and an IR Sensor
Learn how to combine a PICAXE, IR sensors, and a servo motor to create a device that responds to a moving stimulus. Spoilers: I hook it up to eyeballs that can follow a finger. Related Information Servo Motor Control with an Arduino Servo Control with Arduino Through MATLAB Servo Control via USB with the SAM4S […]
Bootloader for 16F87x PIC Microcontrollers
A bootloader enables download of hex-files directly into the flash-memory of a PIC or other microcontroller. The bootloader receives the user program via the PIC’s UART and writes it directly to the program memory (self programming). This feature greatly speeds up the development process, because the chip remains in the target circuit and need not […]
DS18S20 interfacing with pic and avr microcontroller
Microcontroller BoardsRead the temperature in PIC16F/18F Primer Board from temperature sensor ds1820. The PIC16F/18F Primer board uses the ADC pin for reading temperature from temperature sensor ds1820. The reading output is displayed into PC through UART. PIC16F/18F Development Board The PIC16F/18F Development Board is specifically designed to help students to master the required skills in the area […]
