Resolved! L412 documentation error.
I think I found a documentation error in the L412 datasheet. The Quadspi is documented to support two banks in the QUADSPI module description, but I can only find the pins for BK1, which I assume is the first bank. My guess is that the QUADSPI module...
Resolved! simulator for STM32U585
We want to know that which simulator supports for STM32U585.
STM32F407 Ref Manual Bus Matrix - Typo?
Histudying the DMA of the STM32F407 MCU, I came across Figure 1: System architecture.It says DMA_PI for GP_DMA1 but DMA_P2 for GP_DMA2.I reckon that DMA_PI is a simple typo and should be called DMA_P1 and stands for the DMA peripheral bus.Would you a...
Resolved! Hardfault randomly when I do sprintf
Hello everyone,I'm developing a firmware for an STM32F767 and I have a problem that happens randomly and I can't figure out why. From what I could analyze looking at the stack I think the problem comes when doing a sprintf and I have the hypothesis t...
Resolved! Is it normal for the port reset to be 100ms in the USB Host software? (Min. 10 ms, max. 20ms)
Hi,From RM0090 (Rev 19 - February 2021), page 1393:"Host enumerationThe application issues an USB reset (single-ended zero) via the USB by keeping the portreset bit set in the Host port control and status register (PRST bit in OTG_HS_HPRT) for aminim...
HAL_UARTEx_ReceiveToIdle_IT fails to initialize
Hello There,I'm using STM32H7A3 and facing a weird issue with HAL_UARTEx_ReceiveToIdle_IT() API.STM is connected to Cellular Modem via UART. When I turn on the modem via some GPIOs, initially it throws some init data. But when I call HAL_UARTEx_Recei...
In MCU STM32F103RETxLQFP64, UART program stop system
To,Sir or MadamI am making a embedded system with MCU STM32F103RETxLQFP64. In this MCU pin PC10 and PC11 is multipurpose pin. I use it for UART.In project, PC10 and PC11 is used as GPIOs. I change functionality of pin. I used pin PC10 for UART4_TX an...
BL4S5I-IOT01A issue
Hello there! I am using the B-L4S5I-IOT01A board. After setting up the AWS process, I have opened tera term to configure the device. After I configured the tera term once I press the reset button on the board, no information is being displayed on the...
PC13/PC14/PC15 pins on the STM32F103CBT6 usage
Hello,I have a question related to the GPIOs PC13/PC14/PC15. Due to the fact that in my project I am running out of the other GPIO pins I have a question related to those pins above. I know that those pins have limitation to max 3mA sink current so d...
