Feel the sound!!

The nostalgic 20 year-old Macintosh analog amplifier meets 21st century audiophile.

The C1+ HiFi Shield is a high-resolution Digital to Analog Converter(DAC) for the ODROID-C1+. This is a special sound card for the C1+, that is optimized for the best fidelity audio playback quality. It delivers a nicely balanced sound, solid, deep, wide and nicely layered.We’ve analysed the the audio quality of the HiFi Shield DAC output with the famous industry standard equipment, Audio Precision. The Audio Precision is a high performance audio analyser optimized for the digital audio product.

The analog output of the HiFi Shield is connected to the equipment and measurement data shows on the host PC.
This picture shows a basic configuration of the set-up. Note that I disconnected the external amplifier when we measured the line-out audio quality.

The Signal to Noise Ratio (SNR)
The Noise Level in dBm
The Frequency Response and RMS output level in dBV
The Total Harmonic Distortion + Noise Ratio  (THD+N)
The FFT spectrum analyzer for 1Khz signal

This is a great idea if you want an audiophile set-up with ODROID-C1+. Enjoy a variable output connecting directly into a power amp or active speakers.

Good Bye ODROID-U3

Exynos4412 platform has been the most loved products for the last 3 years. The ODROID-X was the first on 11th of July, 2012. And the family models of the ODROID-X2, U2 and U3 followed it. The ODROID-U3 was the latest model with Exynos4412 processor.

We have got the notice from Samsung that Exynos4412 will be discontinued soon. Because their SoC semiconductor production line is upgraded to the next generation like 28nm and 14nm. The Exynos4412 was made with the slightly old 32nm process. The more critical reason is that Samsung DRAM memory production has moved to the LP-DDR3/DDR4 technology while Exynos-4412 can use only the old LP-DDR2 memory which must to be pre-assembled on the SoC (Package-on-Package). So there is no way to keep buying the key component securely anymore to make the U3.

The ODROID-U3 was the most loved model by Hardkernel members. We have tried to keep this model even the price increases. The price of ODROID-U3 was $65.00 and we had to increase it to $69.00 this year due to material cost increase. But, we cannot make the ODROID-U3 even at higher price now.

We are really sorry that we couldn’t expect this situation earlier, and that caused any inconvenience who needs more U3 boards.

Now, the ODROID-XU4 will replace the position with the next generation processor, Exynos5422 Octa-core. The ODROID-XU4 has better performance and better connectivity with similar price range. We will make a long term plan with ODROID-XU4 supporting for a couple of years.

Thanks,

from Hardkernel members.

Moving to new office

We have just moved to new place. It’s a two-story building. Our new address is below;

[English] 475-1 Mananro, Manangu, Anyang, Gyeonggi, South Korea ZIP:430-852
[Korean] 경기도 안양시 만안구 만안로 475-1 우:430-852
The first floor is duplex type warehouse. We need more time to organise it.
The second floor is our main office. The developers are working here.
A garden on the rooftop. We can have lunch here when the weather is good.
Following the Korean traditional shamanism, we prepared some food and bowed preying for people’s safe and for being Hardkernel forever.

Volumio Audiophile Music Player for Odroid C1 released

Time to enjoy the great Volumio audiophile music player on the ODROID-C1.

Michelangelo Guarise (The creator of Volumio) has announced the Volumio OS image for the ODROID-C1 today.

We have a 1.5 Ghz quad Core CPU, which on paper is faster than many competitors (not only the PI). I’m not able to say how those figures are actually a sensible improvement, as I just started looking at the Amlogic SOC ( which seems quite ubiquitous in embedded multimedia appliances).

But what makes it really interesting for Volumio based scenarios are the Gigabit Ethernet, the eMMC memory slot (sold separately) and the integrated IR receiver. Add that Hardkernel seems to have the widest range of accessories for their boards, and you get that we can consider the C1 one of the best candidates to power a Volumio system.

Talking about real-world performances: the Odroid C1 delivers one of the smoothest Volumio experiences. It boots faster, and loads faster than the high-specs comparable quad-core boards (UDOO, Cubox-i).


More exciting news.

ODROID-C1+ is coming with a native I2S interface to support the HiFi DAC add-on boards. It will be available in the middle of August.
Volumio 2 is coming with four exciting key words Speed, Modularity, High Fidelity and Future Proof.

For those of you with an ODROID-C1, grab the image from the DOWNLOADS page as usual, and drop your feedbacks on this thread !

Setup

Setting up your C1 as a Volumio music player is dead easy, and the project’s website has documentation to guide you though the steps.

– Download Volumio image for C1 from http://volumio.org/get-started/
– Install the image on an SD card (2GB or larger). Installation guide is here.
– Connect the C1 and a USB-DAC to your amplifier and the network
– Boot the C1
– On any PC/Mac/Phone/Tablet, browse to http://volumio.local
– Configure NAS locations, Samba shares, etc,
– Add file to the playlist, sit back and listen !

First impressions

On the C1+, 192Khz/24bit FLAC/WAV files in a NAS server could play back flawlessly thanks to the 1.5Ghz quad-core processor and Gigabit Ethernet connectivity of ODROID-C1.
We could control the full features of Volumio with iPhone or Android smartphones. The Web UI does well on mobile.

Android for the Embedded System

Do you want to control various GPIO/ADC/PWM/I2C/UART/1-Wire devices on Android?
Quick & Easy to make a nice GUI application with Java on Android ?
Can we call it “Embedded Android” ?

We’ve prepared 5 examples with some proper Kernel drivers for the ODROID-C1.
It is very basic and essential to learn the Embedded Android.
Note that you must update the Android OS image to enjoy below examples.

LED on GPIOs control with ADC input

PWM Duty control GUI

I2C sensor access and Display temperature, pressure, humidity, UV index, illumination and so on.

UART read/write access. You can test Tx and Rx signals.

1-wire access example can read the DS1820 sensor values from two nodes.
