I2C what?

The I2C (Inter-Integrated Circuit) protocol was invented 1982 by Philips. Thanks to it's simplicity and use of only 2 wires it is still very popular and widely used. Every Enclustra Module uses at least one I2C bus to communicate with several chips. Be it EEPROM, Real Time Clock (RTC) or clock generator: They are all connected via I2C to the FPGA.

The Enclustra I2C Application Note describes different possibilities to make use of the I2C bus to interface with the different I2C devices on Enclustra hardware. The Application Note gives an overview of the I2C bus in general and lists all the different devices present on Enclustra hardware and their capabilities (in terms of I2C communication).

We wish you a Merry Christmas

The year 2020 will soon be history – finally. Corona has shaken up the economy, workflows and communication. Many self-evident processes became laborious and complex overnight. Thanks to the great effort and high flexibility of everyone, fortunately most of the problems could be compensated.

Despite working from home and an increased coordination effort – and of course our loyal customers, that is you – Enclustra is able to close 2020 successfully.

We’d like to thank you for putting your trust in us. We look forward to a successful collaboration in 2021. The entire Enclustra team wishes you a merry Christmas, a happy new year and a prosperous and healthy 2021.

The Embedded Vision Platform

Are you looking for a platform for your next embedded vision project? The search is over: The Enclustra Mercury+ XU8 and Mercury+ XU9 System-on-Modules (SOM) abstract the high complexity of the Xilinx Zynq UltraScale+ MPSoC EV devices and reduce time-to-market from years to months.

The SOMs integrate the Xilinx Zynq UltraScale+ MPSoC EV with fast DDR4 ECC SDRAM, eMMC flash, quad SPI flash, dual Gigabit Ethernet PHY and dual USB 3.0 on a tiny footprint of just 74 × 54 mm, and thus formin a complete and powerful embedded vision platform.

Virtual FIFO, the smart way

The Stream Buffer Controller IP Core is optimized for FPGAs and implements a versatile Stream to Memory Mapped DMA bridge with up to 16 independent streams. The IP core allows data buffering in an external memory device to provide virtual FIFO capability with up to 4 GByte memory size. It provides an AMBA AXI4-Stream interface for each write and read data stream. A common memory-mapped master interface (AXI4 or Avalon) is provided to access the external memory device.

The IP core is highly configurable in terms of operation mode, buffer size and buffer address for each stream. The configuration is done over a memory-mapped slave interface, either by an embedded CPU, an FPGA Manager application or an application-specific stream configurator controller in VHDL.

Motion control, in the fast lane

The modular Universal Drive Controller IP Core includes everything needed to control up to eight axes (i.e. motors) at control rates above 200 kHz, from the A/D converter interface to position, velocity and current controllers, position detection via encoder or resolver and control logic for power stages. DC, BLDC and 2- or 3-phase stepper motors are supported. Field-oriented control is available for brushless (BLDC) motors, and microstepping is supported for stepper motors.

A software API allows to access all functionality of the Universal Drive Controller without having to know the exact layout of the register bank and the meaning of each field within every register. The API is written in ANSI-C and can be ported to different CPU architectures easily or used in device drivers.

Thanks to the Evaluation Kit for Intel and Xilinx FPGAs it's a snap to add drive controller capabilities to any FPGA design. The kit provides a full featured design platform to build motion control applications. It provides an out-of-the box hardware platform with reference design, to reduce development time and allow you to focus on your target application — get all the details: More info >
