Hi all,
I'm doing some CANBus to work at 1Mbit rate. I made like the schematic on PCA82C250 (schematic in anex). When I'm using the optos, many of my messages are lost becouse bus error. When I remove the optos, the CANBus works without error. Can someone give me a hand?
Details:
1) My CAN Controller is a dsPIC30F4012.
2) VDD and Vss are another +5V and another 0V
3) My optos are 6n137 (10 Mbaud).
4) The 100nF capacitor are ceramic and they are very close to the optos.
5) Rext from PCA82C250 is zero (operates at high frequency)
Thanks
Santini
