Hi,

I am just assigned a project to use STM32-E407 to read from ADC and report via Ethernet. We are using Arduino IDE. currently I have basic setup working, I can upload LED blinking sketch via USB-OTG1 and it works.

But when I tried to upload basic Arduino Ethernet example, I got errors. Can any one point me to some STM32 Arduino examples?

Thanks in advance!

That example assumes an external board connected via SPI so will need extensive changes or find another example.
