Why on STM32CUBEF1 code version 1.8.1 bit FLASH_ACR_PRFTBE is not define? while on previous version on 3.5.0 it was defined.
STM32F1_3.5.0 has bit description of FLASH_ACR_PRFTBESTM32CUBEF1_1.8.1 has no bit description of FLASH_ACR_PRFTBE

How do I use the Ethernet PMT remote wakeup filter register for STM32F407?
What is the polynomial in CRC16?Crc16-ccitt, CRC16-IBM or something else?I tried everything I could, but it didn't work?Can someone help me?Here's how I set up this register:uint32_t wakeup_filter[8] = {0x00ffffff, 0x00000000, 0x00000000, 0x00000000,...
Can I use ST's VID and PID?
HelloI'm using the USB CDC class on my STM32H7.Currently, I am using ST's VID (0x0483) and PID (0x5740).I have four questions.1.Can I use ST's VID and PID in our final product version?2.If so, can I redistribute ST's Virtual COM Port driver to our cu...
STM32G070: TIM6 not working after jump from builtin bootloader to user code
Hello,i work with STM32G070KBT and i jump from my code to the buitin ST bootloader. Then i use SPI to upload my new code/binary and send the Go command. I receive an ACK but nothing happen. My code is not executet or stops working early.If the bootlo...
How to tell if a terminal program is listening to a CDC device?
I am using STM32Cube_FW_F7_V1.15.0 with a STM32F723IET6 implementing the internal HS USB as device. I have implemented the CDC VCP device. I plug the USB cable into a host computer, running either Windows or linux. If I am running a terminal progr...

hello everyone Hello to everyone,I have a project where I need to save data on a usb disk and communicate with the computer. I designed a circuit with a type A connector on the usb fs (a11 a12) line and a type b connector on the usb hs (b14 b15) line...
Resolved! It´s possible to program the MC via the virtual COM in a nucleo board like the Nucleo-L4A6ZG?
The ST link on the board creates a virtual com port, conected to the LPUSART1 of the micro L4A6ZG.What I´m trying to do is to program the micro throught this com port. To do this, I try this sequence:Put boot0 to high, by shortcircuiting pins 5-7 of...
