Get early access to the next-generation STM32Cube HAL drivers for STM32U5A major update to STM32Cube HAL drivers, called HAL2, is now available for preview on GitHub. It supports the STM32U5 series. Building on over 10 years of experience, HAL2 deliv...
Hello! I trying to use usart1 in main cycle, and VCP USB in usb interrupts. USB works fine, until i not using usart. When i try continiosely send data in main cycle, usb stack not working(enumeration fails):while (1) { HAL_UART_Transmit(&huart...
Hello,I have some general questions about USB subsystem in STM32F723:Q1- What is the maximum throughput in STM32F723 when working in USB HS with DMA enabled in device mode? with and without USB stack overhead?Q2- Is there any difference in throughput...
Hello,I want to learn how to interface USB3300 as an external PHY circuit with stm32f407g-disc1 board.I tried running examples on my board of similar kind but I am not able to understand the flow and eventually I am not able to edit the example acco...
The System View Description (SVD) file for the STM32F1 series does not contain a file for the STM32F105. Because the product selector lumps the 105/107 into the same view, can I assume that the STM32F107.svd file can be used for the STM32F105?Also, d...
My project involves a STM32F1 interfacing with a Linux machine as a USB CDCACM device, where the Linux machine will send some packets that need to be received/parsed on the MCU. I'd like to configure an interrupt for when the MCU receives the data pa...
Hello,What is the difference between dedicated endpoint with normal endpoints in STM32 USB?Thanks in advnace
Hello,I'm using the P-L496-CELL02 development kit and I'm running a POC in order to demonstrate a potential customer the performance and stability of the L496+Quectel+ST cellular library.For that I created based on the X-CUBE-AWS 1.4.1 pack an MQTT ...
The STM32 reference manual RM0090 describes in chapter 3.8. the One-time programmable bytes (512). This is great to store, say, a public key.The Annotiation Notes document AN5156 describes - for all processors of the family - among others the feature...
Does the ADC need to be initialized in a special way for the USBPD stack to work properly?I am trying to implement PD on a STM32G431 and the USBPD stack doesn't seem to work. If a powersource is connected, the CAD state changes to ATTACHED but then i...
Hi,I am working on Nucleo STM32H743ZII am using a 64byte size custom usb hid when I send my data frames i get an offset of 6 zeros as shown here :Any ideas where it comes from ?Regards,Gabriel
