Re: STM32H743 I2C

Hi,

Look of other I2C examples, API is the same. You could try to ask on the Discord server, probably somebody already used it on h7.

Re: Serial USB differences F413/F407

Moving in "bug reports".

This is strange because F407 is very old and the driver is known to work, I need to verify on my old board and then on a newer board again.

Re: Broadcast Ethernet from F405 and DP83848

This one /demos/STM32/RT-STM32-LWIP-FATFS-USB One of the targets is an F4 like in your case. You could simplify it by removing the FatFS and USB stuff if you don't have those peripherals on board. The easiest approach would be to get one the boards supported out of the box, on the F4 Discovery you c...

Re: Broadcast Ethernet from F405 and DP83848

Hi,

Not enough info for me to tell. I suggest making the normal LWIP demo (the one with HTTP server) work on that board, that would prove correct functionality of the whole stack.

Once it works add that code and try it.

Re: [not chibios] stm32cube bug how to get help from ST?

The only hope is ST then, I will send this link to somebody in the MCU division but don't expect immediate reactions.

hi,

You could use OpenOCD for programming I think.

Re: Read from UART

Using TIME_IMMEDIATE as timeout makes functions non-blocking.

Re: Read from UART

The function is right, adding intervals is not useful probably, the read function is blocking, also note it handles timeouts (look at the returned value), you need to consider that in your communication protocol.

It is often not so straightforward to get communication done right.

Re: Read from UART

Hi,

Use the Serial driver, you just read/write from internal queues, no need to mess with interrupts, it is all done within the driver.
