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...
Hello all, I want to take ADC reading at regular intervals based on timer 1 (used OC mode). The timer must trigger the ADC to take a reading and the ADC in turn will trigger the DMA to transfer the ADC reading to memory. To check that the timer is ru...
Hi every one, I am not able get Free RTOS SDK and support for STM32F469 eval - kit to interface with SD card, Graphical LCD and USB - c type. Kindly help me if it is available. Thanks and Regards Pankaj Jharbade
I am working with an STM32F107VCT6TR MCU to communicate with an M95M04-DRMN6TP component over SPI3.The pins are set up as follows:PB7(93) -> HOLD(7)PB6(92) -> W(3)PA15(77) -> S(1)PB5(91) SPI3_MOSI -> D(5)PB4(90) SPI3_MISO -> Q(2)PB3(89) SPI3_SCK -> C...
Hi,I'm trying to use an interrupt with CMSIS_RTOS2. The user button is configured to use as an interrupt source:When I push the button, the system freezes. I suspect the interrupt flag doesn't get cleared but I have no idea why.There is nothing (yet)...
