Following the name change to WinPicProg I’ve now bought the domain name winpicprog.co.uk so all future updates will be under this address, with links from my old pages. I’m happy to try and help with any problems people have, either via email or (preferably) via the new PHPBB support forum, where other users will be […]

Description Hardware Software Running the RFM12 Demo Download Links Description This project shows how to do wireless communication with the RFM12 tranceiver modue in combination with a PIC microcontroller. The RFM12 is a low costing ISM band FSK transceiver module. There are different module variants available which support different frequency bands: 315/433/868/915MHZ. The module has […]

What you will get is a competitive, state-of-the-art 32-bit processor based on the RISC-V architecture, with a rich set of peripherals, and full debug support. At ETH Zurich and Università di Bologna we have put many of the ideas that we have developed through our research on ultra-low-power parallel processing (PULP project) into PULPino. It […]

How to interface LED with Microchip’s PIC microcontroller? How to connect LEDs to a PIC microcontroller? LED interfacing is the stepping stone for microcontroller development. This is a simple embedded program for PIC 16F877A to interface LEDs, suitable for beginners who wish to study basics of embedded microcontroller programming. The program is developed through Micro […]

This project can steer 10 different things wireless with the use of a normal TV-remote-control with the RC5 protocol, from manufacters like Philips, Grundig and Marantz. If the Proton PIC Basic compiler is available, then you can ofcourse change the number of channels. Use it as follows: When ‘TV’ mode is selected on your remote-control, […]

This code is basically just from three sources, merged together with a few tiny tweaks by me. jsSHA, a JavaScript implementation of SHA/HMAC Generate Time-Based One-Time Passwords With JavaScript Espruino HID Example (Note I’ve just discovered that Espruino has its own hmac implementation so I can possibly drop jsSHA) The main thing you need for […]

This simple project uses a Dallas DS1820 one wire temperature sensor and a pic 16f628 microprocessor. A simple temperature regulator where a LED symbolizes the Fan. Data derived from the DS18s20 is a 9bit centigrade temperature measurement. As mentioned the temperature sensor communicates over a one Wire bus that requires only one data line and ground for […]

This is a Solar Tracker. A full size, internet cloud connected, smartphone accessible Solar Tracker built mainly from 2x4s and plywood, employing wooden peg gears, recycled curtain poles, nuts, bolts and threaded rod. The solar tracker uses a home built electronic controller incorporating WiFi, stepper motor drives, accelerometer and magnetometer. The tracker was designed to […]

Chapter 3: PIC16F887 Microcontroller The PIC16F887 is a well known product by Microchip. It features all the components which modern microcontrollers normally have. For its low price, wide range of application, high qual-ity and easy availability, it is an ideal solution in applications such as the control of different processes in industry, machine control devices, […]

It has long been predicted that inter-chip and even intra-chip data links must ultimately move from the electrical to the optical domain. Prior work in the field has typically involved lasing light sources being fabricated separately from, and tightly coupled to, a host IC. A group of researchers from the UK has demonstrated the first […]
