UIO-4035 both have two CAN ports (can1 & can2).
Use the “candump” and “cansend” tools directly to send and receive messages. The tools have been embedded into the system.
Send and Receive Data
Mode of connection：
Send and Receive Data
Taking can1 as receiver and can2 as sender:
# #---- Can1 as receiver ----# # # ip link set can1 down # ip link set can1 type can bitrate 1000000 dbitrate 2000000 fd on # ip link set can1 up # candump can1 & # #---- Can2 as sender ----# # # ip link set can2 down # ip link set can2 type can bitrate 1000000 dbitrate 2000000 fd on # ip link set can2 up # cansend can2 123##155 # #----If no error, the receiver will receive the following data----# # can1 123 [01] 55
See more details of the usage of “candump” and “cansend” :
# candump --help # cansend --help
Note：
1. Receiver should run before sender.
2. The “bitrate” and “dbbitrate” should be the same for sender and receiver
