Ethernet and MQTT Library for ch32v208

This library provides support for Ethernet and MQTT on the ch32v208 microcontroller. It is based on MQTT examples from WCH and depends on the following libraries:

• ch32fun
• funny_libs

Currently, this library is in beta version.

Usage Example

A usage example can be found in the file src/example.cpp. Please refer to the comments in this file for more detailed information.

Network Configuration

It is crucial to set the correct values in the net_config.h file for the library to work properly. Pay special attention to the following parameters:

• WCHNET_NUM_UDP: Set this to 1 if you are using DHCP.
• WCHNET_NUM_TCP: Set this to the number of TCP connections (for example, for two clients, set WCHNET_NUM_TCP = 2).
• WCHNET_NUM_TCP_LISTEN: Set this to the number of server listeners (for example, for one server, set WCHNET_NUM_TCP_LISTEN = 1). Each listening socket requres an additional TCP socket (i.e. increase WCHNET_NUM_TCP by 1)
