example code for STM32-E407 board

[abrown]

Hi,

I got the STM32-E407 board but have had a hard time finding straightforward code examples.

I would really appreciate it if someone could share with me some example code that I can use to get the board up and running with:
- simple "ping" ethernet example
- simple UART communication example

The examples are for either out of date IDEs or bloated environments like IAR which is way more than I need. Either PlatformIO or Arduino is good.

Thank you!

Did you try the Olimex package for Arduino and STM32 boards? There are also two simple demos inside - blinking LED and LED and button demo.

Refer to chapter 7 of the user's manual on how to install the package:

https://www.olimex.com/Products/ARM/ST/STM32-E407/resources/STM32-E407.pdf

Yes, I did follow those instructions. Unfortunately the Ethernet examples (for instance UDPSendReceiveString) do not even compile (even with the E407 board selected).

Here's my error output for example:

This is expected. The general Arduino examples won't work for STM32 chip and LAN8710/LAN8720. The good news is that there is library that works for STM32 F407 chips and has support for LAN8720 (it is the same for LAN8710):

https://github.com/khoih-prog/EthernetWebServer_STM32

It might need some slight tweaking on pins and so but it is pretty much the closest you'd get to something ready.

Which pins, specifically?

[LubOlimex]

First ctrl + f "LAN8720" on the page and check all information regarding it.

Then compare the pinout from this table:

https://github.com/khoih-prog/EthernetWebServer_STM32?tab=readme-ov-file#1-wiring

with the schematic of STM32-E407. Focus on hte right side of the LAN8710 chip - you will see that the library uses port B pins (13, 12, 11) while our design uses port G pins (13,14,11). Compare all pins this way.

will take a look. thanks
