Guys - if this project is going to be able to stay credible then decisions can not be made without either a) learning actual details or b) trusting those who already have - as happens with the other aspects of the project. This can not be any different. I am more than happy to educate about USB in general and the small simple Cortex-M3+firmware I propose to use in particular. I have done so several times before in two-three hour long workshops at events in different countries, and it was exceptionally well received each time. I really do think that restricting UART communication to onboard between the little Cortex-M3 and the STM32 brings real significant technical advantages; that way the serial protocol stays in a far more controlled environment, and speaking a real USB protocol with the host allows the host software to be much simpler, without that USB protocol requiring any design effort to speak of. If you are able to describe real issues with my suggestion then I am very eager to learn about them. Maybe they can even be resolved. Finally, supporting FTDI in any way is both poor politics and technically risky. In their latest driver update which is pushed through Windows Update they started injecting ASCII text into the serial bytestream if the driver considers the connected chip to be a clone. FTDI sells a poor product at too high a price and are being increasingly shitty about other companies reusing their sucky protocol, in a way which will affect *end users at runtime*. They don't deserve any more business, not mine, not yours. //Peter _______________________________________________ Tech mailing list Tech@cryptech.is https://lists.cryptech.is/listinfo/tech
