HI, I have a problem with the example program provided by stmCUBE IDE and my board nucleo-H723ZG, the example program (LwIP_TCP_Echo_Server LwIP TCP Echo Server Application)
Hi,I have a problem with the example program provided by stmCUBE IDE and my board nucleo-H723ZG, the example program (LwIP_TCP_Echo_Server LwIP TCP Echo Server Application) contains inside a README. txt that explains how to run the example, but it is...
How is ping setup in LWIP stack ?
I want to know if ping feature is automatically set up when lwip stack is up and running in STM32 controller ?
SPI Data Register Problem
Hi,I`m using STM32G431 for practicing SPI protocol knowledge, but face some problem like below.I use �?HAL_SPI_Transmit_IT】API to send (0x5A,0xA5) data out, but measure with Oscilloscope and figure out the wrong data.In �?SPI_TxISR_8BIT】show how d...
Timing-dependant hard fault error during SPI communication
Hello, I am facing a strange hard fault error during SPI interaction loop with the display that only takes place under certain circumstances, prob. related to changes in timing. Minor changes in code at random places alter WHEN it happens. This is my...
How DMA works for USB HS
I am wondering how DMA works for USB HS. As far as I know it is a "machine" to copy memory to another place. And how is it implemented for USB ? We have there a FIFO queue and from what I observed in the driver, the data from the FIFO are copied by t...
Can someone point me at an example of a non-HAL basedSTM32 peripheral driver?
I'd love to see a well structured, non-HAL based STM32 peripheral driver that is actually working in a real world application. For my purposes, a H7 UART driver that uses DMA would be great. If it implemented idle character detect and/or character ma...
