Arduino for STM32

"Maybe a power issue ?" - A good idea. But I had A1, A3, A4 and A5 working without problems.

"all other can be commented." - I even tried to comment all (!) the pins in the ethernet-section - with no effect. Maybe, there are different "default" pin definitions working somewhere in LwIP.h or ...

Hello,

I'm running into a strange problem and can't find a solution: I'm trying to use A0-A5 as OUTPUT-pins while having an mqtt client runnning.

#include <LwIP.h>
#include <STM32Ethernet.h>

// this must be unique
byte mac[] = {0xDA,0x30,0xDE,0xEE,0xDE,0xEC};

// Enter an IP address for your ...

Thank you so much - that did the trick!

Hello,
I have an interesting problem: For a project, I need to use 5 UART ports and ethernet (for mqtt). On a custom pcb I wired my serial connections like this:

UART2_RX: PD_6
UART2_TX: PD_5
UART4_RX: PC_11
UART4_TX: PC_10
UART5_RX: PD_2
UART5_TX: PC_12
UART6_RX: PG_9
UART6_TX: PG_14
UART7_RX: PE ...
