    interfacing USB flash dish and AVR (MCU)

    avr with flash disk Sorry I don't understand what you can? In this interfacing, USB disk is 'client' (or 'slaver') If you wan't to read or write into USB disk, You'll have to simulate USB HOST. It's really complex. :cry:I was afraid of simulation USB HOST, one of which create 1ms Header Frame...

    Problem with TRXQ1 wireless RS232 communication

    I just constructed two circuit with MAX232 and TRXQ1. My purpose is wireless communication between of Computer1(node A) and Computer2(Node B). I built it the same at sample of datasheet on page 9 with MAX222 is replaced MAX232 and tied mode pin (number 12) of TRXQ1 to ground for broadcast mode...
