[oc] HDLC Controller



Hi,
I'm about to evaluate the performance of the HDLC core from your Site. By now I have managed to build a connection between 2 controllers, and verified that the data was well transfered only in certain cases. The "transparency" of the communication is not 100% ensured, since the value of the data bursts framed affected dramatically the value of RxFrameSize. In many cases, the Rx-module detects 1 Byte more than really sent by the Tx-module (N Bytes). The data obtained in RxDataBuffOut is valid during the first N Bytes, but an additional Byte is received, which is difficult to discard automatically (How could we know this extra-Byte was added?).
I would appreciate inputs regarding this topic, besides further hints for this core.
Thanks,
