Reprogramming the Web_Relay_Con V2.0 HW-584 Network Module Did you buy one (or more) of these Network Modules and then find disappointment in the software on the board?

• All of the modules have the same MAC address. That's a problem if you want more than one on your network. And the supplier does not give you a way to change the MAC.
• If you change the IP Address the device returns to its default IP Address when it power cycles. That makes it pretty much useless even if you only put one on your network - unless you're OK with it always having IP Address 192.168.1.4.

I was disappointed enough that I decided to reprogram the device to provide a web server interface that let's you change the IP Address, Gateway (Default Router) Address, Netmask, Port number (a REAL port number), and MAC Address. I also added the ability for the device to remember all these settings through a power cycle. Any Relay settings you make are also saved through a power cycle.

Three configurations of the firmware are available. They allow the Network Module to have a) 16 outputs (to drive 16 relays), or b) 8 outputs / 8 inputs, or c) 16 inputs. All three are included in the file set in binary form for immediate programming into your device. If you want to manipulate the source code the selection of the configuration is available in the uipopt.h file.

IMPORTANT NOTE: The software provided in this project only works with the “Web_Relays_Con V2.0 HW-584” which is based on the STM8S-005 processor and ENC28J60 ethernet controller. I haven't tried it with any other version of the hardware. I think the V.1 FC-160 is based on a Nuvoton processor and this code and the tools are incompatible. NOTE: I am not in any way associated with the manufacturer of this device. I only wrote code to run on it for my own hobby purposes, and I am making it available for other hobbyists.
