Hi, I am trying to communicate with i2c DMA without interrupt. My MCU is STM32G474RET6.I've read that it is possible but can't find how to do it. How can i communicate in slave mode with i2c dma? Since my interrupts disabled, can't use the callback f...
Hi We use an STM32L452 with an external LSE (32.786 kHz) oscillator. We would like to use PC13 as a GPIO input with interrupt. In the errata sheet for the STM32L452 (ES0388 Rev9) I find the following entry:“2.2.12 PC13 signal transitions disturb LSED...
Hi, I have a confusion between these 2 USART Block diagram. Figure 1 and Figure 2.Figure 1 shows that the flow of the RX is from RX ENDEC block -> RDR -> Receiver control.Figure 2 shows that the flow of the RX is from RX ENDEC block -> Receive shift ...
Hi, we struggle to get P-L496G-CELL02 up and running with a plastic SIM. I know that set pin Sim_select0 to LOW to select the plastic SIM. However, I don't know what software to use and how to set it up. I am a beginner in embedded development. In ad...

STM32F303 - Application running fine in CubeIDE debugger, custom board. It will not start as standalone, programmed with CubeIDE or CubeProgrammer with .elf or .hex.I have created an 'attach' run debug configuration, which can successfully display pr...
Firstly, hello, I currently have the Nucleo-F446RE and E22t-900d LoRa module. First of all, how do I connect these two products? Then, how can I send the data I receive via the stm32 card to another LoRa module connected to the USB port of my compute...
Hello,Please forgive me for what is probably a newbie question. What is required to implement an HDMI interface with the STM32F7 or H7 MCU series? Is a DSI-to-HDMI bridge always required? What is the max. supported display resolution?Thanks,Scott
Hi, I'm trying to check I3C protocol with NUCLEO-H503RB and IKS01A1.I just followed below link for I3C. https://wiki.st.com/stm32mcu/wiki/Getting_started_with_I3CAnd I can see that the master transmit the data but there is no ACK from the slave.(I've...
RTC3 of some newer STM32s introduce a RTC mixed mode, where both binary part (32-bit down-counting sub-seconds register SSR) and classic BCD calender (TR/DT) mode are operational.In my case I am using this for classic style BCD alarms together with b...
