Hello, I am writing USB OTG from scratch for a Nucleo-f439zi. Till now I have managed to make it reply to some Setup requests, to be more specific it replies to Device Descriptor and set Address , ( I am currently figuring out Configuration request w...
Originally a reply here: https://community.st.com/t5/stm32-mcus-products/using-swd-pins-to-flash-code/td-p/759046Split to a new thread as this is a new question.Thank you for the solution. However, I have another doubt here. While referring to: STM32...
Hi, I am using STM32H503 controller and wanted to understand if SWDIO pin can be used to flash the code.
Hi,I want to implement USBD MSC using lagecy middle ware and use an SD card as storage.Is there a tutorial like this ? STM32U585 Legacy CDC without Azure USBX Tutorial - STMicroelectronics CommunityBest regards.
Hello everyone,I would like to know the technology node (i.e. 180nm, 90nm, etc.) of the STM32 microcontroller STM32F103C8T6. I can not find this information.Thanks in advance.Best regards.Marco
I am utilizing the STM32F767Zi microcontroller unit (MCU) on a customized printed circuit board (PCB). During the debugging process, we are using the ST-Link V2 ISOL debugger. However, we are encountering an issue where the MCU is not being detected ...
I want to drive havfbridge with STM32G474. I am going to use TIMx with channel1 and channel2 to create two PWM signals, that are 180° out of phase and with the same PWM % that is limited to 0% < PWM % < 49%. Because tohose signals have max 50% duty c...
Option 1:- Use a 10MHz Timepulse signal from the GPS (Ublox M8N) and connect it to the STM32H7.- The STM32H7 will count the timer from 0 to 999999.- To determine when the second has passed and the NMEA signal arrives, check the next timer overflow, w...
Dear sir, dear missis,I'm working with an STM32L053r8 on a step by step know-how. My interface with the bootloader runs fine, and I am able to cover the main features provided through this interface. The issues I try to cover now is the right underst...
I initialize RTC timer by first clearing RTC_CR register,then waiting until WUTWF bit is on, then setting RTC WUTR register to 100, and RTC_CR to 0x4420 (wakeup timer enable, wakeup interrupt enable, bypass shadow). Bypass shadow register is set for ...
