Hello,I've read several forum posts commenting on the STM32 HAL management of LWIP, particularly ethernetif.c and trying to understand the interrupt driven zero copy examples. For reference in my application I do not use RTOS.After updating cube, and...
Can anyone help me please?I'm using LWIP and CGI SSI and http webserver. I've written an html form on my webserver that when submitted sends 16 parameters (each of 32 byte length) as a get. This crashes my webpage and the code never reaches the cgi h...
Hello,I have a STM32 sending a packet a second, up to 25 UDP packets, to another STM32 whose role is to echo these packets back to the sending STM32.Inside the packets is a value which I increment after every transmission.I've noticed that at the ori...
Hi,LWIP: what is the difference between udp_send() and udp_sendto()?What are the use cases for each? The LWIP_RAW_CLIENT ECHO uses udp_send() but also uses udp_connect. Whereas udp_sendto() does not need to connect?Does anyone have example? Thanks
The STM32F070RBT has Hardware Flow Control for RS485, with DEAT, DEDT and DEM bits in USART_CR1 and USART_CR3 registers.How do we identify which series of ICs have these features easily? Is it a particular series or type? The STM32F4 IC we are curren...
