General Description |
Diolan U2C-12, all-in-one USB-I2C, USB-SPI and
USB-GPIO Bridge device, converts PC USB transactions to the I2C Master, SPI
Master transactions and GPIO functions. U2C-12 turns your PC running Windows,
Linux or MacOS into comprehensive I2C/SPI Bus master.
This ultimate USB-I2C/SPI/GPIO Interface Adapter supports different I2C/SPI Bus
clock frequencies. You can choose Fast Mode I2C interface at 400kBit/s or
Standard Mode I2C interface at 100kBit/s and less. Specific I2C Bus frequency
in Standard mode can be selected by USB-I2C API and software. Lower frequency
will allow you to communicate on highly loaded or long wired I2C buses.
U2C-12 USB-I2C/SPI/GPIO Interface Adapter has input and output dual buffers to
support posted (overlapped) USB I2C and USB SPI reads and writes. This feature
allows U2C-12 to increase overall PC USB system performance and reduce latency
in back to back transactions.
With U2C-12 USB-I2C/SPI/GPIO Interface Adapter and Diolan terminal applications
( GUI or command line ) you will get instant access to any I2C slave device and
SPI capable device. You can create your own I2C or SPI control applications
based on Diolan drivers, API libraries and source code examples for C, C++,
Visual Basic, Visual Basic NET.
USB-I2C/SPI/GPIO Interface Adapter has also GPIO ( General Purpose Input Output
) support to let you control and/or monitor digital TTL and CMOS signals.

Features |
-
USB-I2C/SPI/GPIO Interface Adapter Supports Variable and Configurable I2C Bus
Speed Modes.
-
400kBit/s Fast Mode.
-
100kBit/s Standard Mode.
-
Variable Software Configurable I2C Bus Speed in Standard Mode (under
100kBit/s).
If you select Standard Mode I2C bus speed you can configure actual I2C bus
master clock frequency in the range from 100KHz to 2KHz.
-
Posted USB-I2C and USB-SPI read/write transactions support.
To eliminate 1ms USB frame synchronization delay posted ( overlapped ) USB-I2C
and USB-SPI transactions can be used.
-
Multi-level I2C Bus Controller API.
-
Hi level I2C Read, I2C Write, ...
-
Low level I2C Start, I2C Stop, I2C ACK, ...
-
Wire level USB GPIO transactions with SDA and SCL lines.
-
I2C Bus Clock Synchronization (Clock Stretching) support.
To communicate with relatively slow I2C slave devices, Diolan U2C-12 I2C
Bus Master supports clock stretching. This feature is widely used to
communicate with microcontrollers I2C slave module ( PIC I2C, AVR I2C, ... ).
-
USB-SPI Interface Support.
-
SPI Byte Stream Read and Write transactions.
-
Full Duplex ( simultaneous read/write ) SPI transactions.
-
Configurable SPI Bus clock polarity, phase and frequency.
-
Upgradable and Uploadable U2C-12 USB controller FW.
USB-I2C/SPI/GPIO Interface Adapter has on-board I2C EEPROM containing default
Diolan U2C-12 USB controller FW. This I2C EEPROM can be easily programmed with
FW upgrade utility. This feature will let you keep your U2C-12 board up-to-date
by applying FW updates from Diolan.
USB-I2C/SPI/GPIO Interface Adapter can also work with FW uploaded by U2C-12 USB
driver after device is connected to the PC USB bus.
-
PC USB host powered. No external power adapter required.
-
3.3V and 5V operations on SPI bus and GPIO.
-
U2C-12 I2C bus module can operate on 3.3V or 5V when powered by on-board VCC.
-
U2C-12 I2C bus module can operate in range 2.0V-5V when powered by external
VCC.
-
Flexible on-board jumpers set.
-
I2C pull-ups enable/disable.
-
3.3V or 5V, external/internal I2C bus voltage.
-
3.3V or 5V SPI bus voltage.
-
Compatible with USB 2.0 (as well as 1.1 & 1.0) Full-Speed USB device
specification.
-
Windows 98/2000/XP, Linux and MacOS Support.
-
Diolan Driver and API support a number of U2C-12 devices simultaneously.
-
Up to 23 GPIO with TTL and CMOS levels.
