Hi all,We are using an STM32H730IBK6Q.PA10 is not configured and STM32CubeMx generates code that initializes the pin as "Analog" as expected.Now if we enable USB (specifically, when setting `USBx->GCCFG |= USB_OTG_GCCFG_PWRDWN;`), that pin goes high,...
Hi guys, I have a nucleo-l073rz and am developing software for it with iar ewarm. So far everything is working well (programming and flashing via the st-link programmer). In the future, however, I would like to do firmware updates via the serial inte...
Our project is run on the STM32F411E-DISCO board running under Segger Embedded Studio. All Timers TIM2/TIM5/TIM9/TIM10/TIM11 are being used. Under a debug session everything runs correctly. If we leave the board programmed with the debug code and ...
I am trying to use a comparator on my NUCLEO-STM32G474RE dev board.The issue I am encountering is that while the external COMP1 output is correct when measured with an oscilloscope, the output due to HAL_COMP_TriggerCallback is simply a 370 kHz signa...
Most I2C EEPROM (eg M24M01E) need some time after a write command to transfer the written data into the internal EEPROM. During that time (eg max 3.5 ms) the device does not respond to I2C.My question is about the timeOut parameter in the HAL_I2C_Mem...
Body:Hello STM32 Community,I'm encountering an issue with an Ethernet application I'm developing on an STM32 platform, where I can't seem to send UDP packets to a specific IP address within my local network. Broadcast UDP packets are sent and receive...
Hi @STTwo-32Apologies to anyone that would have seen this topic elsewhere on the ST community forum. I was advice to create a new topic.The first time I reported this bug I thought it was a red herring as I did not know how reproduce the bug at will ...
Hello,Newbie here, need help getting printf() to write to USART2.Using IDE : IAR EW for ARM 9.50.1Board: NUCLEO-F401REExample Project:The example project is called UART_Printf. Here is a screen shot of the directoryThis example code can be found here...
I have a complex system comprised of one STM32G474RE that serves as a USB to I2C bridge. The G4 communicates with about a dozen STM32G051F8 chips over I2C. I designed the board with the ability to independently control the BOOT pin of each G0 so I ca...
Hi!I'm having some troubles in configuring the I2C bus on my STM32H747 evaluation board.I've configured it in CubeMX as in the image below, using DMA buffer (rx and tx). Gpio pins are configured as open drain (no pull) and hardware is ok.It seems lik...
