This library implements an SD card Data Logger that runs on ATmega. It has a small footprint, so it can be loaded on an ATmega8, leaving space for user code. It supports SD and microSD cards formatted with FAT16. It also features log rotation.The “Petit FAT File System Module” by ChaN (http://elm-chan.org/fsw/ff/00index_p.html) it is used to write […]

This project explains how to interface the SD card with an AVR microcontroller. In this project an ATMEGA16 microcontroller is used. The microcontroller runs on 5V power supply with a built in crystal frequency of 8 MHz. A 2GB SDSC card from Transcend is used in this particular project, but the code will work with most of the SD

Introduction This project implements a high speed data acquisition system using Mega32 microcontrollers and a Controller Area Network (CAN). Recording data is essential to testing and developing a racecar. Recording what each sensor is doing can tell an engineering how the car is performing, and most importantly, how to make it faster. A well outfitted

This post presents a way for testing and learning the FAT32 system on microSD/ SDHC cards without building the hardware with microcontroller, thanks to Henry Yiu. This project uses the FAT32 library available in my previous post, but does away with the microcontroller part. So, you can use this code with a PC and USB
