Ethernet, USB host+device, and SD-card interface
(C) 2013-2013 André Fachat
This board is a small board that nevertheless packs an SD Card, an Ethernet as well as a USB host and USB device interface on it!
All parts are connected via the SPI65b SPI interface. SD-Cards do SPI anyway, Ethernet is implemented via an ENC28J60 chip. USB is done with a MAX3420 (device) and MAX3421 (host) chip with the usb65 drivers.
SD-Card
This is a test driver for the SD-Card access via SPI65B schematics below.
It initializes the card, reads the operations conditions register, the card id data, and can read and write a block.
Please note that it is clutterd with debug code.
Ethernet
This is a uIP stack with a builtin driver for the ENC28J60 via SPI65B as on this board.
Version: 2.0B
Status: prototype
Notes
This board has been successfully tested with SD-Card, Ethernet as well as USB host and device operations. |
