USB to SPI and I2C Dongle
Code Mercenaries ships a USB to SPI and I2C dongle.
The IO-Warrior56 based dongle offers a simple and easy to use solution to connect SPI and I2C devices via a USB port.
Connecting sensors, service interfaces, test and evaluation circuits and a lot more applications can be easily answered with the IOW56-DG dongle.
The I2C master interface operates at 50, 100, or 400 kHz and allows a throughput of up to 62 kbytes/s. Multi master mode and handshaking via clock stretching are supported.
Up to 12 MHz bitrate with 62 kbyte/s throughput is possible on the SPI interface.
The IOW56-DG dongle is available at Euro 33 (excl. VAT) and is shipped as a set consisting of the assembled and tested PCB, a ten wire cable and two part dongle case. The cable can be soldered to the dongle PCB, allowing flexible pinout to fit the customers application. 5 V and 3.3 V are also available to power small external circuits like sensors.
To allow compatibility with 3.3 V slaves the internal pull up resistors can be switched off under software control. The dongle PCB has solder pads for pull up resistors to 3.3 V on the back side.
The mechanical dimensions of the IOW56-DG dongle are within the limits for a USB standard plug. This prevents the dongle from blocking adjacent ports and allows multiple dongles to be used on a single computer or USB hub without losing ports.
Since the dongle is based on a standard IO-Warrior56 chip the software and development tools for IO-Warrior are useable for the dongle as well. This makes support for Linux, MacOS, and Windows as well as for many development systems available. No specific drivers are required, the dongle works with standard system drivers.

About us and our products
Code Mercenaries is a supplier for the industrial input device and peripheral manufacturers since 1998.
The keyboard and combined keyboard/mouse controller family KeyWarrior, and the mouse controller family MouseWarrior serve as basis for a large number of industrial input devices. A small but vital customer base are the manufacturers of products for the disability market and other speciality input devices.
The joystick controller family "JoyWarrior" serves a broad range of customers from industrial machine/vision control, professional and semiprofessional simulator control, to hobby and model building. A good option for front panel design are the joystick/mouse hybrid controllers MW24J8 and MW24H8 which are switch selectable to work as a mouse or joystick allowing both cursor control and data input via a joystick.
JoyWarrior24F8 is a low cost three axis acceleration sensor. With its small size and simple connection via a USB interface it opens a lot of new application options. The MouseWarrior24F8 variant of this sensor is a mouse replacement that needs no surface for operation.
Applications for the IO-Warrior universal USB I/O controllers are very diverse. Basically only the number of pins and the data rate limits the use of IO-Warrior. It is used in laboratory setups, test equipment as well as in hobby projects or full scale device production either as the core of a device or "just" the interface to USB. IO-Warrior chips control robots and telescopes, do quality control on production lines, take measurements in labs, control switches and displays in front panels or simulator cockpits, or work as the USB interface in many kinds of products.
SpinWarrior is a family of rotary encoder controllers with USB interface. Various models allow from 3 to 6 encoders to be connected to the USB and are suitable for motion control, measurement, or human interfacing applications.
Our philosophy is to provide complete solutions that allow our customers to concentrate on their own strength in developing their end products. The necessary know how for controlling interfaces like USB or PS/2 is encapsulated in our chips.
