Posted on August 03, 2012 at 23:28Arduino is very close to C, if you were able to translate it, you'd just need to set the clock speeds, pins, and SPI peripheral for compatible use.
There IS a project to bring Arduino to the STM32 directly, I don't know what the state of usability is. I suggest you google it.
The ENC28J60 is a stand-alone Ethernet controller in itself. It will do the job, through the SPI port. However, the STM32F4 Discovery has its OWN Ethernet hardware peripheral, however, you'd need a hardware phy to adapt the voltage and current. The DP83848

would do that. I expect the STM32 peripheral library would have a ready example for running ethernet through that phy.
Ironically, it costs more than an ENC28J60 module, even though it is only a phy, not a phy plus controller. However, working through the SPI on the ENC28J60 is probably far more limited than using the STM32 peripheral for bigger projects, and you won't learn as much about ethernet by using the ENC28J60. But, like I say, the ENC28J60 is completely adequate for reading temperature sensors.
