I have setup my STM32 MCU to be a USB Device with OTG FS and when I list the details of the device on my computer, I can see that the USB endpoint used for data transfer is of type Bulk. It works perfectly fine, when I use the function `CDC_Transmit_...
Hi all,We are currently using the stm32h5-hal-library in our project. Our preference is to use the LL drivers rather than the HAL and for the Octospi, we only see a HAL drive for it (stm32h5xx_hal_xspi.c). Is there a LL driver equivalent for this? I ...
I am using internal Temperature Sensor stm32h743zit6 , i notice that when i connect power some time after that it stable temperature approximately 46 degree or 47 degree, after i start streaming it came temperature also stable on this 46 degree o...
Hi, I am trying to use a Nucleo-H745ZIQ to implement the USB CDC HOST functionality over the USB OTG FS port. I succeeded to do it and make it work if the device connected to my board is another STM32 board which is configured as an usb device, and t...
Hi!when I run the HAL example code LwIP_HTTP_Server_Netconn_RTOS I get HAL_ETH_ErrorCallback() called on every packet, but the program seems to work fine.its this bit that gets called (so something hapenning with DMA)if((HAL_ETH_GetDMAError(heth) & E...
I am trying to implement MODBUS-TCP on a TouchGFX generated project. I have successfully enabled Ethernet by following this tutorial on this forum: How to create a project for STM32H7 with Ethernet and LwIP stack working and can ping my board.In the ...
I inherited an old STM32 project (STM32F373) that uses FreeRTOS and the old Standard Peripheral Library (apparently v1.0.0, dated Sept 20, 2012). Among other things, the project uses USART1 with interrupts to receive LIN messages, and also has a task...
we are working on a project where an STM32F4 microcontroller is used as a host to connect with an external device. we are considering using the USB interface for this purpose. Can we refer to the following example to implement USB host functionality ...
I have problems saving data at just under 1Mbit per second to SD, when the SD clock is 25Mbits per second, using the FatFS library. Data is lost, and it is because of the time consumed in performing the ‘f_write’ function for saving data to SD.Could ...
Hi all, We have an STM32H735VGH6 on a custom board with a LAN8742a PHY chip to allow ethernet communication. This custom board is minimally tested so it's possible that there's a hardware issue though I'm uncertain where the issue would be. I gener...
