Documents: GUI Windows Installer / FTDI VCP Driver / D2XX Driver Description: This module provides the ability to quickly test I2C slave devices by generating all of the standard master functions compiled from a simple text script. It is meant as a replacement for those simple and cheap printer port to i2c adapters. Justme Justme. USB to I2C Professional. Additionally the GPIOs, interrupt input and delay functions allow complex control scenarios and testing of your I2C system robustness. The USB-to-I2C Hardware has 3.3K pull-up resistors connected to pin VP on the 14-pin header. USB HID to I2C Master specification support Supports I2C Standard mode, Fast Mode and Fast Mode Plus (FM+) up to 1 Mbit/s 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 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 • … The goal of i2c-tiny-usb is to provide a cheap generic i2c interface to be attached to the usb. share | improve this answer | follow | answered Feb 5 '19 at 17:46. Mouser offers inventory, pricing, & datasheets for USB to I2C Interface Development Tools. With this design user can access multiple peripherals ( i.e. U2C-12 turns your PC running Windows, Linux or MacOS into comprehensive I2C/SPI Bus master. The i2c-tiny-usb project is an open source/open hardware project. 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. What is needed is a USB chip than can act as a I2C master. With plug-and-play USB connectivity, the I²C/SPI Interface Device is a portable solution to communicate with consumer electronics and integrated circuits. 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. When connecting the USB-to-I2C Hardware to an I²C target system, a cable with a minimum of three (3) wires will be required. Provides HID-to-I2C SDK (DLL libraries) for application development. This is the simplest way to communicate with PC using USB. 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. A USB solution has several advantages incl. The SDA, SCL, and GND on the USB-to-I2C Hardware must be connected to their corresponding signals on the target. 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 to I2C Interface Development Tools are available at Mouser Electronics. The converter has an interrupt output. 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. 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.
