I agree with them and what they did. Average of 55ms for 4 commands running on the test on the same PC as the driver. Each of those vendors, in turn, likely subcontract out to other companies for design, manufacturing…even software. We couldn’t possibly hope to manufacture these devices ourselves so we buy them from vendors all over the world. ... on Raspberry Pi we use the python RPi.GPIO library. FT2232 has a nice feature of using 2 serial ports with different configuration simultaenously. Critics felt that FTDI’s actions were unethical, considering that users may be unaware that their chips were counterfeit, or that Windows had automatically installed a driver meant to disable them. So each FTDI based design is lottery ticket and risk for customer. But as always, there are people that find fdti is right, and those that find they are wrong. USB to I²C Development DIP Module, FTDI Chip. Now multiply that out by the hundreds of chips that are installed inside hundreds, if not thousands of units we have in production….any one of which could be a fake that slipped into the supply chain. Hi, I have a FT232H connected to a 16 ch servo controller over I2C. There's even a handful of digital GPIO pins that you can read and write to do things like flash LEDs, read switches or buttons, and more. And the point is not if it is inevitable or not for supply lines to be compromised. But the maker community needs to understand that it is contributing to the problem by buying exceptionally cheap (and possibly counterfeited) parts and products. Of course legally speaking we are in the clear, but our OEM customers wont be happy. Skip to content. It works with Windows, Mac, and Linux, and has a built-in color screen that shows a live “dashboard” of all the I²C activity. Complain all you want – but shut up when you find out counterfeit parts in your hardware has been sending your own personal information to hackers in another country and it’s used to steal from YOU. There is no reason to tell others what to do! If you got hit by the FTDI driver, you were not their customer since the driver never caused problems with the original chips. Some of it is more functional, some of it is more secure, some is cheaper, some is more readily available…the permutations are endless. That’s their choice (legal or otherwise). Requirements. Ftdi Usb I2c Software These drivers appear to the system as an extra Com Port ( in addition to any existing hardware Com Ports ). ... General Purpose USB to GPIO+SPI+I2C. Every single company down the chain then cops one in the backside as a result of something they had nothing to do with. They should have done that from the start, would have caused much less of an uproar. Everything I or my company designs is only uses original manufacturer order codes of course. There are at least a dozen such options out there. The FT201X would be used where an external microcontroller or FPGA needs to transfer data to and from a PC. The USB bridging solutions from FTDI (i.e. USB to I2C Converter Adapter with Virtual COM Port and Hardware I2C Port Supports Fast Serial and 100KHz-400KHz I2C Speeds. @RBSCHARETTE: Exactly. Just select Device ->Serial Protocol->Connection from Polymorphic drop-down menu. The airlines don’t develop these themselves of course, they contract certain international airports to do it for them. With all due respect, this isn’t 1977, and your comment doesn’t accurately reflect how much of the world’s manufacturing is done these days. I get the dmesg ... Stack Overflow. What can the FT232H chip do? Yes, the wiring for the SPI and I2C EEPROMs will be different. Ignorantly buying counterfeit parts is one thing, but I have seen before where a maker claims to have gotten multiple, likely counterfeit, items off of EBAY or ALI Express for less than the cost of a single known manufacturer’s part, and is willing to throw one or two away “because it is still a better deal”. Yes, you can check, their latest driver will put a message into the system log if it finds a fake chip and also sends out a message stating that on the serial side. LibFTDI library; This is an open source library that's similar to the D2XX library and provides a low level interface to FTDI chip functions. The series rounds out with a primer on how to use FTDI hardware to speak the SWD protocol to ARM devices for advanced debugging use. You only need to buy two components from Taobao and make a few soldering points. No, this is about the disgracefully unethical (and possibly illegal) actions of a company that should have at least said “Our drivers are going to disable counterfeit chips on this particular day, here are a couple of utilities you can run to confirm that yours are genuine. UART/Serial USB converter, up to 12Mbps (depending on the FTDI device capability) Bitbang/GPIO support; SPI master; I2C master; JTAG master; PyFtdi provides a pyserial compliant API, so it can be used as a drop-in module to access USB-serial converters based on FTDI devices. This USB2.0 Full Speed IC offers a compact bridge to I2C devices.
