Hello forum,I'm working in STM32CubeIDE with the STM32F107VCT6 on a custom board which successfully run a TCP Server application using Ethernet communication + FREERTOS + lwIP and I'm struggling in enabling AUTOIP feature.My custom board need to be I...

Hello folks,I'm working on a TCP Server implementation on a custom board using Ethernet communication with a STM32F107VCT6 in STM32CubeIDE and I've found a problem in the LWIP generated code (to be sincere the same problem has been verified by me occ...

Hello community, I'm working on a STM32F107VCT6 where I have practically (by means of very basic filtering) shorted on the PCB VDD/VDDA/VREF+/VBAT and VSS/VSSA/VREF-. I've runned out of pins so I was wondering if there were a way to measure the pow...

Hello world,I'm developing a FW for STM32F107VCT6 which can change GPIO direction programmatically: there is a terminal command which can switch individually 7 pins* mapped on different ports between GPIO_MODE_OUTPUT_PP \ GPIO_MODE_INPUT.I'm wonderin...

Ok let's get the hand dirty!Modifying AUTOIP RangeDigging in the lwIP Middleware dumped in the project by the STM32CubeIDE automatic code generator, the range is cleverly defined in /Middlewares/Third_Party/LwIP/src/include/lwip/prot/autoip.h (see co...

Sadly I celebrated too early.Yes, the autoip function is working correctly, but, since the board is a TCP Server (and not a Client), it has to be discovered over the network, and "arp -a" will show the IP up only after communicating with the board (e...

Oh Wireshark, how many times have you saved my ass since my youth?Thank you both for you answers, LCE for pointing out this wonderful solution to the no-dhcp problem (I'm working for Automatic Test Equipments who are big racks full of instrumentation...

Looking to the issue with a cold mind... It makes no sense the LWIP/Target/lwipopts.h "#define LWIP_NETIF_HOSTNAME "myhostname"" since the string is loaded by the code generator in plain sight in the LWIP/Target/ethernetif.h and never used by the c...

Get AUTOIP working on lwIP

lwIP can't assign hostname (until I modify STM32CubeIDE generated code...)

How to measure power supply internally on STM32F107?

How to read GPIO direction using HAL?
