CPU stalling when erasing FLASH on STM32F405
Posted on July 15, 2016 at 16:13Hello,I have a scenario as follows: I have a Timer 2 that gets interrupted every 1ms. I try to communicate (only Tx) with an external device every 50ms by calling a function inside Timer 2. When the system is running ...
Resolved! STM32F103RBT6 SPI slave mode
Hi ST experts, I'm using STM32F103RBT6, and for GPIO's Alternate functions, I want to use default, not remap.Based on its datasheet, I understand that when its SPI2 interface works in SPI master mode, PB15 acts as data output MOSI and PB14 acts as da...
STM32L452 USB virtual com port connect
HelloI have a question. Using the STM32L series, the current USB virtual com port is recognized in the device manager of the PC.Here, I am curious about the maximum number of Com ports that can be connected to the PC.I know that the basic Com port is...
why I can not use LPUART?
I want to communicate with a UART module using an STM32H723 Nucleo board. Receiving data and transmitting over DMA features. İf i choice USART2: PD5 (TX) and PD6 (RX) it works fine? İn same code if change usart2 to lpuart and if i change pins for lpu...

I am having problems trying to use the HAL_SPI_TransmitReceive function. I am using STM32CubeIDE along with the STM32U5G9J-DK2, I am configuring my side as a full duplex slave using the following parameters:I am working with an embedded processor tha...
Resolved! What pins are used for I2C bootloader on the 20-pin STM32F070F6
I cannot figure out which pins to connect to I2C on the STM32F070F6T6 chip. AN2606 says to use PB6/PB7 which do not exist on this part. The only pins that are mapped to I2C1 are PA9/PA10 or PF0/PF1 according the data sheet. My first spin of a boar...
STM32H7 ADC clock prescaler
HelloI'm always confused with the ADC clock config of H7 devices. ok, H7 is not a device for noob but ever after spending days reading datasheets, users manual, appnote, and filling spreadsheets, when starting cube MX, you will always find that the c...
STM32U5 - Real confusion about RTC and sub-seconds tracking. Trying to use it to set time from NTP packets.
Hi all,I'd like to use the RTC as a keeper of real-world clock. It would get synchronized with a (S)NTP server once a day. The RTC would get queried multiple times a day for the current time. The main challenge is that I'd like the timestamps to have...
