Hi Everyone,

Here is a small project that our Applications engineers designed using a UM232H module in MPSSE mode. It acts as a USB to I2C Master bridge to take readings from a Texas Instruments INA219 current and voltage monitor. It also provides a couple of GPIO input lines and (most importantly of course) a flashing LED!

It connects in-line with a USB device and tracks how much current it is drawing from the host as well as the voltage on the VBus line. The 0.1" connector on the rear panel can be used instead if you want to connect it to measure other circuits via jumper wires. This can be really useful when debugging your own circuits and checking how much power they will require.

A program written in Visual Basic NET displays the results on a scrolling chart with different range settings. You can modify the code to talk to other I2C sensors as well though.

Here are some pictures showing the meter itself and a chart showing a USB flash drive which was connected and enumerated accessing a file on the disk.

We have written a document on the project as well as publishing the source code, and you can find these at the links below:

Source Code

We hope this gives you some ideas for some projects of your own ...

Best Regards,
The FTDI Team

Hi All

My name is Mark Butcher, 53, English born and based mainly in Switzerland (M.J.Butcher Consulting - http://www.mjbc.ch/), with regular periods in France and the UK.
Since 2004 I have been developing the uTasker project (available as OpenSource or supported commercial) for a number of single-chip processors which focuses today on NXP Kinetis [my favorites] (and ST Micro STM32 devices, which are also quite popular). http://www.utasker.com/

The uTasker project supports FTDI FT800 and so I will be monitoring the new forum in case anything interesting comes up. Although not a particularly exiting video the following shows how the FTDI emulator has been integrated into the uTasker simulation environment to allow complete development and testing to be performed in Visual Studio in a non-blocking environment but still using the original FTDM supplied demos (with small modifications): https://www.youtube.com/watch?v=XxC3Y2NaaU8
Here is a link to the announcement of this new support at the time: http://www.utasker.com/forum/index.php?topic=1947.0

Professional interests are remote working on embedded development (one of the reasons why I developed uTasker in the first place to allow complete embedded project simulation and remote debugging/support), communication stacks (TCP/IP, USB, Modbus, FAT which were developed for the uTasker project), efficient, reliable project developments (bringing together the previous ones) and supporting a base of users across the word. Have developed and supported projects for customers in >30 countries.

Personal interests are golf (although I am taking this year off) and cycling to keep fit; languages (English, German, French); and, although I don't need a car for day to day use and actively avoid using them where possible, I do enjoy some touring in sports cars and allow myself a few thousand miles a year for such travel. I have a small collection of mainly older red cars but this is what I have fun with in Europe this year: https://www.youtube.com/watch?v=X1-doYnOw8k

Welcome to the FTDI Community!

Feedback from current customers through our usual support channels indicated that a place to share projects and ideas would be extremely beneficial. This will allow us to create a sharing knowledge base for all.

We have therefore designed this community to encourage our customers to interact both with one another and with our technical teams, sharing new ideas and projects.
Please note, this forum has been created in addition to our current technical support services, which can be reached using the contact details, available @ FTDI Support.

Please contact admin@ftdicommunity.com if you have any questions relating to the Community pages
