GHI Electronics,LLC Embedded Master User Manual
Supported Devices
SDHC (SD High Capacity) is newer version of SD cards. SD has a limit of 2 GB. SDHC
solved this problem by converting byte addressing to sector addressing.
Embedded Master supports MMC, SD, mini SD, micro SD and SDHC memory cards.
Eye-Fi
Eye-Fi is an SD card with built-in WiFi. Using Embedded Master, a user can
log data to the SD Card (Eye-Fi), as regular SD card. But now with Eye-Fi, the
files can be wirelessly transfered from SD card to a home or office network.
Eye-Fi is first configured with needed settings for the network in order to
transfer the files later.
WiFi is provided for file transfer only from Eye-Fi. It is not possible to use it for
communication on this card.
MP3
This includes VS1002 and other similar decoders. VS1002 is a low
power MP3 audio file decoder/encoder. WAV or MP3 files can be
transferred using SPI to VS1002 for playback.
Embedded Master can store audio files on the internal flash memory
(as a resource or using EWR) or get the file from an attached memory
device or from the network. Then the file data can be transferred to
VS1002 using SPI.
www.Olimex.com offers a little module with VS1002 chipset.
The pinout of the cable on this module is compatible with
Embedded Master Development System SV1 connector.
Make sure to remove RST, DREQ jumpers and place
EXT/BAT jumper in EXT position on the VS1002 module.
An example code is provided with Embedded Master SDK.
RF (wireless)
There are many available SPI based communication chipsets,
wired and wireless. Nordic is the maker of one of the common
RF transceivers, nRF24L01 2.4Ghz.
Similar to the MP3 module, Olimex offers a module with
nRF24L01 with all required circuitry and a simple on-board
antenna.
The pinout of nRF24L01 module is compatible with SV1 on
Embedded Master Development System. An example project is available on the
Development System page.
