AVR-GCC 7.1.0 for Windows 32 and 64 bit

Here is where I’ll be uploading builds of AVR-GCC for Windows 32 and 64 bit, which will also include Binutils, AVR-LibC, AVRDUDE and Make. I’ll be trying to keep the builds up to date with the latest tool releases when I can.

DIY Digital Wristwatch

Introduction The main incentive behind this project was to see how much I could cram, in terms of both hardware and software, into a wristwatch-like device that is no larger than the display itself. An OLED display was chosen for being only 1.5mm thick and not requiring a backlight (each pixel produces its own light), …

AVR USB RGB LED Controller

While working on an update for my CPU Usage LEDs project I thought why not just make it into a universal RGB LED controller? The CPU Usage LEDs controller took a value between 0 and 255, worked out what colour it should be and then fade to that colour. This was very limiting; changing what …

Bluetooth Net Monitor v2

This post only goes over the new stuff in the network monitor, I’d recommend having a look at the original post first. New PCB design The new PCB is now an almost single board design, just a separate board for the USB connector. The old monitor had a small main board which connected to the …

Millisecond tracking library for AVR

This is a lightweight library for keeping track of time to millisecond accuracy, the data type for storing milliseconds can be easily configured, it supports ‘unsigned long long’ which can keep track of time for 584.9 million years before overflowing! Any clock frequency up to 20MHz can be used, most of the commonly used frequencies …

Bluetooth Net Monitor

A newer version of the Bluetooth network monitor can be read about here, but I’d recommend carrying on reading this post first. Whenever I want to see why a download is going a little slow or getting lag on an online game I’d have to log in to my routers web page or SSH in …

Getting Bluetooth modules talking to each other

Before we start, please note that most Apple devices don’t support the virtual serial link profile that these modules use. A really easy method of making your projects wireless is to use serial Bluetooth modules, these modules take standard serial data and transparently transmit it via Bluetooth to another connected Bluetooth module, no extra code …

nRF905 AVR/Arduino Library/Driver

The nRF905 is a radio transceiver IC similar to the well known nRF24L01, but operates at 433/898/915MHz instead of 2.4GHz, has a much longer range and a few extra IO pins. However the nRF905 data rate is only 50Kbps compared to nRF24L01’s 2Mbps. This library offers quite a bit of flexibility: Optional use of interrupts, …

LCD Image Viewer

This is a quick project I made to try out a 1.8″ colour LCD display from Ebay, the microcontroller code is very simple, after initializing the display it just waits for serial data and sends it straight to the display. Image processing is done by the host program, open your image (drag on to the …
