WCHNET library integration #60

Hi, I'm trying to implement wchnet library in Arduino framework on platformIO, but I run into a problems. So, I succeed to add wchnet as library in platformIO, and it compile without problem, but it's not working. As far as I can trace, problem is in interrupts. MCU freeze on TIM2 initialization and if I remove TIM2, ETH_IRQHandler does not start and ETH_LibInit does not start. it probably collide with some previous initialization of timers, but I can't find which one.

After I make this work I plan to make complete implementation of Ethernet.cpp so that this will be compatible with other Arduino libraries.

Can you help me with this?

The WCHnet library works in the PlatformIO integration with the CH32V307 example. I have personally tested https://github.com/Community-PIO-CH32V/platform-ch32v/tree/develop/examples/webserver-ch32v307-none-os and documented the results.

I also had the same idea of pulling in the wchnet library, or adding in the lwIP stack in source code form + adding the integration interface between the ethernet hardware and lwIP.

This may also overlap https://github.com/openwch/arduino_core_ch32/issues/38

Hi Max,

THX, sorry, I forgot to mention that I'm trying to implement this with Arduino framework. Yes, this one is working like charm, I test this, but for no-os I use MRS and looking to switch to VSC/PlatformIO. My idea is to create Ethernet (Ethernet, Client, ...) wrapper for Arduino framework, so that we can use all Arduino libraries.

I see. I'll look into this for ch32v307, The millis() code uses the SysTick timer of the CPU, PWM uses TIMx timers, but usually nothing should analogWrite() by default.

I succeed to track it toNVIC_EnableIRQ(TIM2_IRQn); line, where he freezes. But I noticed something odd, I see that in this repository there is a wiring_analog and other analog files, but in my installation, there is none of this. I use some old version; I will try to reinstall.
