dspic33fj128mc804 ECAN问题

大家好!MUDSPIC只接收BYTE0(8字节数据字段)小于0x80。7FXX-XXX-XXXX-XXXX数据字段的包被成功接收。80xXXXX-XXXX-XXXX数据字段未被接收。接收到的IDS和其他所有的东西。JPG显示了CAN总线上的流量。TX包有ID1C1 190 191。应答包有ID 18Fi,使用来自Cicrochip的CE129的例子。关于,卢卡。

    Hi to all!.
I have a problem with receiving standard packets.
Mu dspic receives only if byte0 (8 bytes DATA FIELD) is less than 0x80.
Package with 7FXX-XXXX-XXXX-XXXX data field is received successfully.
Package with 80XX-XXXX-XXXX-XXXX data field is not received.
With byte0 from 0x80 to 0xFF the packets are not received.
The ids and everything else are ok.
the jpg show the traffic on can bus.
The tx packets have id 1c1 190 191.
The reply packets have id 18f

I use the examples from CE129 from microchip.
Regards, luca.

是否有人试图查看CAN RX中断是否在TBX包上以BYTE0为0B100000接收?DSPI3F

    Can someone try to see if the can rx interrupt gets on reception with a tx packet with byte0 at 0b10000000?
