Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
My program has the option of sleeping for a period using the RTC to wake or sleeping until the wakeup pin is set high. Both these functions work perfectly if I talk to the outside world using a uart.However, I configure CDC as a serial port SLEEP doe...
Hi,I am trying to understand the interrupt vectors for the USB interrupts for the STM32G4. In the reference manual (RM0440) it shows that there is a USB_HP and USB_LP interrupt. However, I cannot find any mention in the USB interface description that...
Hello everyone here, I have a STM32L43x µC and I wish to read the Memory size when I am in Bootloader mode. I tried using the function Read Memory command to read the register at address (Base address: 0x1FFF 75E0) which contains the Memory size. Unf...
Hello community,I'm currently having issues or perhaps not fully understanding the procedure of writing data to the MCU bank 2 and then switching to this bank to run the program from bank 2.My setup for now is using a custom protocol for sending the ...
I have VBUS sensing enabled and when I step through the call to HAL_PWREx_EnableUSBVoltageDetector(), you'd expect a difference in the bit states in the OTG_HS_GCCFG register but there is no difference whether the cable is plugged in or not.I find it...
I wanted to implement a simple USB device only on a STM32F407. When I enable it in CubeMX under USB_OTG_FS I get a DP and DM line and there is an option to activate the VBUS line. Is activate VBUS absolutely necessary? It is after a simple device onl...
Hello,When I try to Enable Ineternal DMA Option , Winodws gives "USB Device not recognized message"I am using Winodws 10 and every thing works fine if I disable this optionHow I can use this option?and could it offload the controller?Best RegardsHoss...
With the USB sample code that I have, I get the following error:"device descriptor request failed" The heap size = 0x1000, so I do not think that is the issue and I do not see any bug in the code.
I came across this Ethernet example:https://community.st.com/s/article/How-to-create-project-for-STM32H7-with-Ethernet-and-LwIP-stack-workingIt is giving me an issue regarding configuring HSE in bypass mode. The maximum core frequency l can get is 96...
This thread is a new problem discovered while investigating a different USB-PD issue in another thread. @Yohann M. recommended that I create a new thread for this issue. Here is the link to the other thread: https://community.st.com/s/feed/0D53W0000...
