I am attempting to reconfigure Pin 8 (datasheet default assignments are PB6/PA14-BOOT0/PC15-OSCX_OUT) from PA14-BOOT0 to PB6 GPIO Output Open Drain (GPIO_MODE_OUTPUT_OD) a short time after start-up.My current attempt (code below) does not accomplish ...
A new question moved from this thread. In many examples they use the Vref int for the calculation of the temperature. Do I need it for the C0 also or can it be done without?
Dear STM32 users and developers, This new thread is back and is dedicated for our technical developers community to share last STM32 updates, the first part will be products documentation news such as datasheets, Erratas, Applications notes followed...
Hi everyone,I am using a STM32H563RG and I need the RTC to work even if the VDD is powered off. To do that, I am plugging a battery on the VBAT pin to power the RTC and the Backup domain. But I tested it and it seems the RTC is stopped and the backup...
Hi STM32 community.I'm working on an embedded system which uses a RK3399 CPU (running Linux, functions as a USB host) and a STM32F302CC (Runing FreeRTOS, functions as a USB device). This runs on a custom motherboard. They communicate with each other ...
One of the AF options on SPI1 is to use the SWD debug pins PB3-PB5.How can this be used in reality?Pretty obviously you can't do SWD breakpoints when SPI1 is thus mapped!But assuming no SWD debugging is needed, and you use SWD just to program the FLA...
Hello everyone,I’m working on a control unit board based on the STM32F407VETx (LQFP100) microcontroller. During development I noticed that some pins configured as external interrupts (rising edge) were being triggered more often than expected.To bett...
Hey. I'm trying to use my H7's usb interface and i've currently set it up as a cdc device.What i'm trying to implement though is the following. The stm is supposed to create a virtual connection with either a python app or a tera term terminal.Is the...
I have a situation where a USB endpoint stops working due to a control packet being NAKed in the handshake phase. I've traced the problem down to the STM USB stack setting DCTL.SGONAK = 1 in response to an INCOMPISOOUT event, yet in the case when it ...
Hello, I have a problem that I am having a hard time figuring out.My project is using an STM32H743 as a USB host on a custom PCB. Both OTG_HS and OTG_FS ports are connected to different devices. OTG_HS is using the internal PHY and operating at full-...
