STM32Ethernet
The STM32Ethernet library allows an STM32 board to connect to the internet.
It is based on the Ethernet library provides by Arduino.
This library is fully compatible with Arduino Ethernet library (https://www.arduino.cc/en/Reference/Ethernet).
Examples allow a quickstart.
This library could only be used with STM32 board with Ethernet compatibility.
Ex:
- NUCLEO-F429ZI
- STM32F746G-DISCOVERY
The LwIP library must be installed to use the STM32Ethernet library.
Both libraries are available through the Arduino Libraries manager.
Click on "Sketch" menu and then "Include Library > Manage Libraries..."
Search "LwIP" then install "LwIP" and "STM32Ethernet"
Note
-
The library is based on LwIP, a Lightweight TCP/IP stack. http://git.savannah.gnu.org/cgit/lwip.git http://lwip.wikia.com/wiki/LwIP_Wiki
-
EthernetClass::maintain() in no more required to renew IP address from DHCP. It is done automatically by the LwIP stack in a background task.
-
An Idle task is required by the LwIP stack to handle timer and data reception. This idle task is called inside a timer callback each 1 ms by the function
stm32_eth_scheduler(). ADEFAULT_ETHERNET_TIMERis set in the library toTIM14.DEFAULT_ETHERNET_TIMERcan be redefined in the core variant. Be careful to not lock the system in a function which disabling IRQ. CallEthernet::schedule()performs an update of the LwIP stack.
