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 s...

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 controll...

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_7...
