Arduino-STM32-Ethernet

Arduino stm32 example for W5x00 ethernet modules.
This project uses this library.

Software requirements

PlatformIO will automatically install the required libraries according to the ini file.
Great!

Platform IO installation

PlatformIO

$ python3 --version
Python 3.7.3

$ sudo apt install python3-pip python3-setuptools

$ python3 -m pip -V
pip 18.1 from /usr/lib/python3/dist-packages/pip (python 3.7)

# pip installed by apt is old, so update to the latest.
$ python3 -m pip install -U pip

$ python3 -m pip -V
pip 20.3.1 from /home/orangepi/.local/lib/python3.7/site-packages/pip (python 3.7)

# Update wheels.
$ python3 -m pip install -U wheel

$ pip3 install -U platformio

Hardware requirements

STM32F103 Development Board
W5100/W5200/W5500 Ethernet Module
About $5 for aliexpress/eBay.
W5100 is for 5V only.
W5500 can be used at both 3.3V / 5V.
ST-LINK/V2 or ST-LINK/V2.1 Module
Arduino-IDE only supports ST-LINK V2.1 adapters.
But OpenOCD used by PlatformIO supports both V2.0 and V2.1.
PlatformIO allows you to use cheap Chinese ST-LINK adapters.
You can get it at a low price (about $2).

You can use NECLEO board as ST-LINK/V2.1
USB-TTL Converter
For Serial monitoring.
External Voltage Regurator
W5x00 ethernet modules require a lot of current.
BluePill or BlackPill board cannot supply too much current.
It is more stable when supplied from an external power source.
AMS1117 is often used.

Selecting the Ethernet type controller (W5100, W5200 or W5500)

It is automatically selected inside the library.

Wiring

PHY	STM32
MOSI	PA7
MISO	PA6
SCLK	PA5
SS	PA4	*1
RST	RESET	*2
3.3V	3.3V	*3
GND	GND	*3

(*1)
You can specify any pin in platformio.ini.

(*2)
Pull up when there is no RESET pin.

(*3)
BluePill or BlackPill board cannot supply too much current. It is more stable when supplied from an external power source.
