    Urgently looking for coding example on set-up + use of HDLC capability of STR710 device.

    - Does anyone in this STR7 MCU forum have practical experience on using HDLC on these parts?

    Thankyou - any help or comments you may have in this context will be welcome!

    Hello Avnet_FAE,

    Bellow you find some HDLC Caracteristic used to determine maximum speed using HDLC and Manchaster coding,

    The STR71x HDLC has been used by customer in the following

    conditions:

    TX: 921KBit (manchester)

    RX: 250KBit (NRZI)

    Anyway our engineer verified that the maximum baudrate could be:

    TX: APB clk (APB=32MHz), but, due to the fact that the pad cannot reach

    more than 16MHz, clock in TX should be divided, at least, by 2.

    RX: APB clk/16.

    hope this can help you.

    With regards,

    Hich :-?
