Additionally the GPIOs, interrupt input and delay functions allow complex control scenarios and testing of your I2C system robustness. USB to I2C Professional. USB-to-I2C includes the USB-based hardware and Windows software and driver that is compatible with 64-bit versions of XP, Vista, Windows 7, Windows 8, and Windows 10. USB to I2C Professional is a general purpose I2C and SPI interface tool that allows a user to communicate with any I2C or SPI slave devices. In order to send data to PC (in Slave Mode), a I2C master addresses this converter as slave and writes the data on the I2C bus. USB to I2C Interface Development Tools are available at Mouser Electronics. It is meant as a replacement for those simple and cheap printer port to i2c adapters. The device is an I2C slave, capable of operating up to 3.4MBit/s, with low power consumption (8mA). The i2c-tiny-usb project is an open source/open hardware project. FT200XD is a I2C slave chip, so it cannot be used as a master to talk to another I2C slave like the BME280 in the question. USB HID USB CDC CONFIG I2C Master UART BUS MATRIX GPIO ADC/DAC USB Bus I2C Bus TXD/RXD PIN GP Pins MUX IOC CLKR Internal Oscillator USB Module and Transceiver ... • LED_I2C (OUT) – USB-I2C traffic indicator (factory default) • ADC3 (IN) – ADC Channel 3 • … U2C-12 turns your PC running Windows, Linux or MacOS into comprehensive I2C/SPI Bus master. This is the simplest way to communicate with PC using USB. The goal of i2c-tiny-usb is to provide a cheap generic i2c interface to be attached to the usb. With this design user can access multiple peripherals ( i.e. This design uses the SLS proven IP Cores such as USB 2.0 Device, SD/eMMC Host Controller, I2C Master and Altera's ADC Moduler and UART Controller IP Core. The converter has an interrupt output. We now have a modern USB C connector on the board (instead of micro USB), a I2C switch to connect D1 and D2 for easy I2C interfacing, 3V power output pin up to 500mA, and a Stemma QT connector that lets you plug & play any Stemma QT or Qwiic devices, sensors and displays. Provides HID-to-I2C SDK (DLL libraries) for application development. When connecting the USB-to-I2C Hardware to an I²C target system, a cable with a minimum of three (3) wires will be required. UART, I2C , SPI, ADC ) with single USB interface. The I²C/SPI Interface Device is a master or slave interface for inter-integrated circuit (I²C), or master interface for SCSI Parallel Interface (SPI) devices. Mouser offers inventory, pricing, & datasheets for USB to I2C Interface Development Tools. Thus it is possible to inform a I2C Master that … USB Human Interface Device (HID) class: No driver installation needed for Windows, Mac, Linux, and Android. The SDA, SCL, and GND on the USB-to-I2C Hardware must be connected to their corresponding signals on the target. USB HID to I2C Master specification support Supports I2C Standard mode, Fast Mode and Fast Mode Plus (FM+) up to 1 Mbit/s The USB-to-I2C Hardware has 3.3K pull-up resistors connected to pin VP on the 14-pin header. A USB solution has several advantages incl. FT201X – Full Speed USB to I2C Bridge: This USB2.0 Full Speed IC offers a compact bridge to I2C devices. What is needed is a USB chip than can act as a I2C master. Dimax 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.
