Introduction
ECB（Ethernet to CAN Bridge）is an Ethernet to CAN adapter, the function of this adapter includes signal conversion between Ethernet and CAN. The adapter is equipped with STM32F429VET6 Master Chip and has 10/100Mbps brandwidth. The default IP address is 192.168.1.30, and the Ethernet protocol is UDP with default interface number 2000. The ECB adapter has 2 independent 1 Mbps CAN bus lines that are insulated, which increases CAN communication brandwidth in the system, decreases communication delays, promotes system’s real-time performance and achieves control of multiple actuators series connection system with complex closed-loop design.
Our ECB’s principle graph and BOM, along with Ethernet communication protocol are all open sources. Users could develop on ECB by themselves based on their own requirements. In this way, it promotes the efficiency of users’ new product development in order to accelerate their listing timing.

Instructions for operating ECB
Note: Since there are multiple ECBs connecting with the same computer, IP and MAC addresses cannot be duplicated. Visit “changing IP and MAC address” to change the ECB’s IP and MAC
Changing IP and MAC addresses
Download
- Visit this link download linkto download SDK and relevant documents, or directly run the codes below.
$ git clone https://github.com/innfos/ipChangeTool.git
- Go to ipChangeTool menu, and modify the administration authority:
chmod 777 ipChange
- After confirming there is only one ECB or ECU has been powered and connected to the computer, run the codes below.
./ipChange -ip=<1~255> -mac=<1~255>
- Be advised that you can only change the last digit for modifying IP and MAC addresses. e.g. The IP address of an ECB is 192.168.1.30, you can only modify the “30”.
Ethernet IAP firmware upgrade
-
Startup: After powering up the ECB, the system will go to the bootloader program in the default setting, the system will jump to users program after 5 seconds. The system will keep staying in the bootloader if the ROM is empty.
-
Ethernet IAP software: update ECB firmware through Ethernet IAP software. For downloads and instructions please refer to the link below:
- Erasing users program: under the bootloader program, using Ethernet IAP software to erase users program.
-
Jumping back to the bootloader program from users program: In users program, you can jump back to the bootloader program through Ethernet IAP software. If succeeded, the system will stay in the bootloader unless you reset the system or upgrade the firmware.
-
ECB firmware upgrade: under the bootloader program, you can upgrade ECB firmware through Ethernet IAP software. See resources below
