More exactly – by a speed of up to 5 Gbps. Elegant, small, but mainly fast USB 3.0 reader is a universal device for transfer of files from all common memory cards.
FPhotos and videos have become a common part of various devices, like for example information panels with touch panels and many other. However multimedia files are usually big files. Nowadays high-capacity memory media enable usage of such big files, but as we know, transfer of such big files can last a considerable time. It is especially obvious when we need to write many-Gigabyte files to several cards.
AM530 can be up to 3-5x faster than usual USB 2.0 readers. It supports advanced specifications like SDHC UHS-I, SDXC UHS-I and CF UDMA6/7 and fully employs the speed of fast memory cards (100 MB/s). Through 5 slots, it supports Compact Flash, SD/ MMC, SDHC, SDXC, micro SD, Memory Stick Pro, memory Stick Duo, M2 and xD memory cards, and it is compatible with USB 2.0/ USB 1.1. Short USB 3.0 cable is included too.
AM530 is a suitable complement to fast industrial memory cards Apacer from our portfolio. AM530 will suit to every workplace also thanks to its elegant design with a brown metallic finish. In case of interest, please contact us at email@example.com

This is my first AVR based hobby project and the most successful one compared to my all previous stuff. I am 100% satisfied with this work.. Few months ago, I tried to make a wav player using a PIC16F877A. It worked anyway, but the audio quality was not so good for higher sampling rate because that chip doens’t have enough ram and thus I couldn’t implement a good data buffer. But when I bought an atmega32 microcontroller, the first thing came to my mind is to make a good wav player…Now, I have completed my work and the audio quality is really amazing…
NOW I can say that, my wav player IS ABLE TO PLAY 8 BIT MONO/STEREO with maximum bitrate of 1300kbps for mono and 1600kbps for stereo … ie it can play an 8 bit mono wav of sampling frequency upto 160KHz and stereo upto 96KHz without any noise or trouble!!!!! (at OSC 16.450MHz).

At the beginning this project was to buy a led sign to interface with my home automation network. This automation network display information like temperature, wind speed, humidity, etc. I had bought on EBay a LED Sign but when I received it I got a surprise! There was no serial port to program messages… After a couple of days, I look inside to see how it was built.

SD / MMC cards support a SPI mode. By connecting it to an AVR’s SPI port, it can be used for general storage relatively easy. Here I demo the use of an SD / MMC card as general storage for electronics projects. I am using it with a 1MHz Atmel AVR atmega8, standard 2GB microSD card with adapter sleeve, and using a PWM port as a cheap DAC for sound output. I first loaded the SD card with pre-recorded sounds at 8KHz and 8-bit unsigned linear. I then read them in real time from the SD card and write the values to the OCR so that they set the duty cycle on a PWM port. I use a simple RC low pass filter as a cheap DAC (Digital to Analog Convertor) that is output to a speaker.

This project by “elm chan” produces sound using an ATtiny861. A MicroSD card is used as storage media and also SD and MMC can be used with proper socket conversion. It is controlled in SPI mode via USI. The audio signal is output in PWM and it can drive loudspeakers directly. [via]

The Daisy is a multipurpose sound player for embedded applications. It can be used as a standalone personal music player,as the sound for an art project, in a kiosk, as a museum tour guide, in a toy, or anywhere that high quality embedded audio is desired. It uses MMC or SD flash memory cards so storage size is unlimited. It has several interface modes for either human or machine control.
The Daisy is based on the Microchip PIC18F45j10, which is a new family of PIC microcontrollers. They are capable of running at a full 40MHz at 3.3 volts, which makes them ideal for this application. Also, most of the pins are 5 volt tolerant, easing interface with other microcontrollers. The other chip on board is a VS1011 from VLSI, Finland. It is an .mp3 and .wav decoder chip, a DAC, and a headphone amplifier all in one 28 pin package. I’ve been fooling around with this family of decoders since 2001 and I have never found an mp3 file it couldn’t decode… and the sound is very good!
