Low Cost ARM11 Development Kits Runs Main-line Linux and Android

The well-know Chinese ARM9/ARM11 embedded device manufacturer Witech Co., Ltd recently released another Low cost ARM11 development kit for their TE6410-CORE System on Module with the name of OK6410. With the price of US$ 139.00 for an ARM11 OK6410 development kit plus a 4.3 inch TFT LCD, Witech pronounce that the OK6410 features the best price-performance ratio to date.

Not to mention the 4.3″ TFT LCD. The OK6410 development kit features the Samsung S3C6410 micro processor clocked to 667MHz, 128MB DDR RAM, 256MB NAND Flash, and 12MHz, 48MHz, 27MHz, 32.768KHz clock source, and targets embedded development training, industrial control equipment, vehicle navigation device, HMI, multi-media terminal, POS terminal, PDA, etc. The Samsung S3C6410 is one of the highest performance mobile processors available today. Along with its speed, 2D/3D multimedia capabilities and rich memory support, it offers the industry’s broadest set of on-chip peripheral interfaces, including TFT-LCD 24-bit true-color controller, system manager for power management, 32-channel DMA, 4-channel timers and 12-bit ADC for touch-screen applications. All the major high-level operating systems are accommodated.

Beside the workhorse S3C6410 micro processor, 128MB DDR RAM and 256MB NAND Flash which are soldered on the 6-layer TE6410-CORE System on Module, the 4-layer OK6410 carrier board provides wide varieties of PC-style I/Os including USB Host, USB Slave, four serial ports, SD card slot, stereo audio IO, LCD/Touch screen interface, WIFI connector, CMOS camera connector and keypad connector and so on.

Specifications listed for the OK6410 include:

In addition to the outstanding hardware specifications, Witech (http://www.arm9board.net) also provide demo BSPs (Board Specific Packages) for a variety of Embedded Operating Systems including Mainline Embedded Linux, Windows CE, Android, and uCos/II. “Such demos should be quit helpful in shortening customers development circle and reduce their Time-to-Market”, says Witech.

Detection of ECG signals on personal mobile phones

ABSTRACT: Life-threatening cardiovascular diseases require early de-tection or diagnosis. A standard procedure, long-term ECG monitoring of cardiac patients is currently the best way to reduce the number of heart failures. Dry and washable tex-tile electrodes embedded in comfortable garment or in a wearable chest belt have been proven very effective for a long-term ECG monitoring in comparison to the conven-tional Ag/AgCl electrodes. Hereby, we present a wearable ECG chest belt, which contains stitched textile electrodes for ECG detection and analog preprocessing circuits em-bedded in tiny cell-phone plugs. With them we achieve on-site ECG processing, display and transmission using a dual-core OMAP3-based embedded system. Our experiments have shown promising results of textile electrodes along with our hardware and embedded system in conveying a better ECG signal quality having a clinical significance and hence enabled long-term ECG recording in a daily life.
