If you want to use a finished board, you could use one with an STM32 (USB host and device on the same chip), e.g., this one should work nicely: https://www.olimex.com/Products/ARM/ST/STM32-H407/open-source-hardware The libopencm3 project should have suitable drivers for the chip. Note sure what they have in terms of USB. STM also provide some interface code, but that one is a little odd. If making a board from scratch, I'd take two KL2x and (each can be USB host or device, but not both at the same time) and connect them to each other. There, I could use my existing firmware from Anelok, and teach it new tricks. Also, the KL2x pair should be smaller, cheaper, and may be easier to handle than an STM32. > I've searched a bit and > found the FTDI Vinculo2, which has usb host and slave dual connections, but > unfortunately the toolchain is closed and only for windows :( Uuh, I'd stay away from FTDI. If you value openness, they're not your friends. - Werner _______________________________________________ Qi Hardware Discussion List Mail to list (members only): [email protected] Subscribe or Unsubscribe: http://lists.en.qi-hardware.com/mailman/listinfo/discussion
