Queue behaviour with azure rtos/threadx, internally buffered?

Hi, I am experimenting with sending data across queues and noticed that if the queue size is just one deep I would expect a second attempt to add to the queue to wait until the corresponding receive function is called.However after a first call to tx...

Since STM32Cube_FW_F7_V1.17.0 the HAL I2C Functions do not work the same. For a huge project that used to work with no issues on STM32Cube_FW_F7_V1.16.2 the I2C Data line goes low and the Firmware reports an HAL_I2C_ERROR_SIZE. Is there a known bug?

We are using a STM32F76ZI for a consumer device.The Firmware used to work fine with no errors.Since STM32Cube_FW_F7_V1.17.0 the I2C communication does not work all the time reporting random I2C Errors. The most common error is HAL_I2C_ERROR_SIZE that...

lwIP / TCP tx'd pbuf ACK'd?

Hello,I have to admit that this is more a question concerning lwIP, but as I'm using a STM32F7...And the search engines haven't helped yet.I need to transmit TCP packets quickly, without waiting for TCP's ACK.Payload for these packets come from an ar...

LWIP Web server on RAW, SSI tags do not work in STM32CubeIde 1.10.1

Hi, stm32 LWIP Web server on RAW, SSI tags do not work in STM32CubeIde 1.10.1if you will run this project in STM32CubeIde 1.8 and 1.9 everything works well!PS - I checked LWIP, everything is the same, including the version!

What is the I2C transaction size for the STM32 HAL_I2C_Mem_READ Function? I know for Arduino the I2C transaction size is limited to 32 bytes but I was unable to find similar information about STM32's I2C. I'm currently using the STM32L010RB chip.

Exception thrown at 0x0000000000000000 when calling connectDfuBootloader with "USB1"

I am getting exception thrown at 0x0000000000000000 when calling connectDfuBootloader with "USB1". This works fine in another program but in my current program I am getting this exception error. Do you know what I'm failing to do?Mark Sloan

Interface IP camera with STM32

Hi all,Is it possible to capture image from an IP camera which is connected to an STM32 MCU via ethernet port? An external RAM can be added to handle the data traffic. Due to multiple reasons I cannot use a digital camera instead of an IP camera.Does...

How to check connection alive in LWIP?

Hello,I am using STM32H743 and imported the sample project LwIP_HTTP_Server_Netconn_RTOS. Is there anyway to indicate the TCPIP is still alive or not in case the ethernet cable is disconnected?Thanks
