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 :-?
