Did you try the code from the mbed library. It has not worked for us but perhaps you can get it to work.
no it dint work. The code is
1. sending code:
- include "mbed.h"
- include "CAN.h" DigitalOut led1(LED1); CAN can1(p30, p29); Serial pc(USBTX, USBRX); char counter=0; int main() { pc.baud(9600); can1.frequency(125000); while(1) { if(can1.write(CANMessage(0x42, &counter, 1))) { led1=1; counter++; pc.printf("Message sent: %d\n", counter); } wait(3.0); led1=0; wait(3.0); } }
2. Receiving code:
- include "mbed.h"
- include "CAN.h" DigitalOut led1(LED1); Serial pc(USBTX,USBRX); CAN can2(p30, p29); int main() { CANMessage msg; pc.baud(9600); can2.frequency(125000); while(1) { if(can2.read(msg)) { led1=0; pc.printf("Message received:%d\n", msg.data[0]);
} wait(3.0); led1=1; wait(3.0); } }
