Hi. I have an uart managed by dma rx channel.In order to disable the error callback when a framing error comes (HAL_UART_ERROR_FE) I have comment out the line of codehuart->ErrorCode |= HAL_UART_ERROR_FE;Is there a grace way to do that, without to ed...
Hi, in order to resolve an address I using the function dns_gethostbyname(). Sometimes the customer uses a standard ip address like 192.168.1.123. Is there a way to determine if dns_gethostbyname() is necessary or not?
Hi, I have a problem with HardFault_Handler.Sometimes, when I'm writing into the flash it happens.After many days on searching still I don't understand why it happens and what it means.Has someone got a suggestiom for me?
In auto baud rate situation is there a way to know the actual baud rate of the uart, anthe the other parameters linke size and parity?huart1->Init.BaudRateseems to have the initial parameters but not the actuals.
Hi, I don't want to use the callback. I just want to check a uart state or value, if there is one, to know how much bytes have to been send and if the buffer is completely sent.
I have written the code above according with these articles:https://techoverflow.net/2015/02/03/reading-the-stm32-unique-device-id-in-c/https://gist.github.com/ElectronicaXAB3/2e1085be2719990f178d0557dc8314d1http://blog.gorski.pm/stm32-unique-idBut a...
Many thanks for the explanation.Now I'm trying and there is a problem.The auto baud rate feature does not work if the first byte is 0x02. It work if I send for example "aa" (0x6161). It is very strange.The main problem is: I have to attach a 485 bus ...
Many thanks, it works.The auto baudrate works only one time from the startup. My situation it is different because the baud rate can change at runtime.So I have implemented the uart reconfiguration each second to re enable the auto baudrate.Do you th...
