•
len
represents the length of this frame.
•
data_buf
is the content of this message.
For example, In the ‘send’ example, we have:
unsigned
char
stmp[8] = {0, 1, 2, 3, 4, 5, 6, 7};
CAN.sendMsgBuf(0x00, 0, 8, stmp);
//send out the message 'stmp' to the bus and tell other devices
this is a standard frame from 0x00.
6. Receive Data
The following function is used to receive data on the ‘receive’ node:
CAN.readMsgBuf(
unsigned
char
len,
unsigned
char
buf);
In conditions that masks and filters have been set. This function can only get frames
that meet the requirements of masks and filters.
•
len
represents the data length.
•
buf
is where you store the data.
