Hello,
I use two adm3054 to connect two microcontroller (pic18f2680) with the CAN bus. The actual bit rate is 35 Khz and communication between the two pic is correct.
The yellow waveform is CANTX
The blue waveform is CANH
However if I try to increase the bit rate, the bus does not transmit the correct data. It become always occupied by the same trasmission that is repeat indefinitely as if the other device never ack.
The yellow waveform is CANTX
The blue waveform is CANH
All the chips are on the same breadboard and the power supply is 5 volts. On the bus there are two 120ohm resistances between CANL and CANH.
Would you please kindly give me some suggestion?
Thank you.
