Re: TXT Controller and I2C speed

Today I designed the interface to test my I2C modules on the Fischertechnik TXT Controller. For this I made a simple interface box with Fischertechnik parts to fix the print. The PCB is a simple single side version for mounting and testing the I2C modules. Diagram, layout and installation plan are ready. The layout film is drying, in order to be able to etch early tomorrow. After that, the tests follow.

There was a fourth module, the FRAM, but there is an address issue with the TXT controller ( same internal address range $50-$57) so it could not be connected to it directly on the TXT Controller, however via external hardware it should work anyway. A number of examples for the software I have already found through this forum, so the testing should go pretty well. I will keep you informed of the results (within a few days).

The PCB has just been etched and the components have been soldered. Everything fits neatly in the Fischertechnik housing. A 10-pin cable is connected directly to the TXT controller. The sensor modules are also soldered and mounted. The power supply voltage has been tested. All modules are supplied with the necessary 3V3 voltage. The real tests with the Robo TXT software will follow tomorrow.

Test of the color sensor I2C module TCS34725 connected to the Fischertechnik TXT Controller. With the test program of Dirk Fox I was able to start very quickly. Everything works very well, now I can start a new project to sort colored pearls. The box contains 2300 pieces in 11 different colors. Ideal for designing a sorting robot.
