I request the Ruggedboard Team, to update the Instructions for testing the CAN, Isolated Inputs and Outputs.
I want to interface the Ruggedboard with the Automotive Circuits where we need to use the CAN Bus. As I am Promoting the Ruggedboard to the Automotive Engineering Students by bringing them to IoT Technology where they can apply IoT into Automotive where Ruggedboard will be the Gateway.
For Industrial IoT, there is a need of usage of Isolated Digital Inputs and outputs. So we request to update on this regard also.
I’ve been searching for some decent stuff on the subject and haven't had any luck up until this point, You just got a new biggest fan!.. Face mask

How to test Isolated Inputs and Outputs. Please, share MRAA pin number or sample code either in C or Python for testing Isolated Inputs and Outputs.
For testing CAN, canutils package is highly recommended. We are not providong canutils packge along with NOR flash. So please boot the board from SD card and follow the below steps to test the can. 1.Boot the board from MMC. 2. After booting,check the interface is available or not by giving the below command. $ ifconfig can0 3.To Transmit packets from board to PC. Connect the PCAN device. Give the below commands to test can. Target side: $ ip link set can0 down $ ip link set can0 type can bitrate 50000 $ ip link set can0 up $ cansend can0 123#1232 Host side: $ sudo ip link set can0 down $ sudo ip link set can0 type can bitrate 50000 $ sudo ip link set can0 up $ candump can0 $ can0 123 [2] 12 32 To Transmit packets from PC to Board Host side : sudo ip link set can0 down sudo ip link set can0 type can bitrate 50000 sudo ip link set can0 up sudo cansend can0 123#1232 Target side : ip link set can0 down ip link set can0 type can bitrate 50000 ip link set can0 up candump can0 can0 123 [2] 12 32 Expected o/p : To Transmit packets from board to PC Target side: root@sama5d27-som1-ek-sd:~# ip link set can0 down root@sama5d27-som1-ek-sd:~# ip link set can0 type can bitrate 50000 root@sama5d27-som1-ek-sd:~# ip link set can0 up root@sama5d27-som1-ek-sd:~# cansend can0 123#1232 Host side: USER@ubuntudesk:~$ sudo ip link set can0 down USER@ubuntudesk:~$ sudo ip link set can0 type can bitrate 50000 USER@ubuntudesk:~$ sudo ip link set can0 up USER@ubuntudesk:~$ sudo candump can0 can0 123 [2] 12 32 To Transmit packets from PC to Board Host side : USER@ubuntudesk:~$ sudo ip link set can0 down USER@ubuntudesk:~$ sudo ip link set can0 type can bitrate 50000 USER@ubuntudesk:~$ sudo ip link set can0 up USER@ubuntudesk:~$ sudo cansend can0 123#1232 Target side: root@sama5d27-som1-ek-sd:~# ip link set can0 down root@sama5d27-som1-ek-sd:~# ip link set can0 type can bitrate 50000 root@sama5d27-som1-ek-sd:~# ip link set can0 up root@sama5d27-som1-ek-sd:~# candump can0 can0 123 [2] 12 32
