im confused about the TIMPRE bit in the RCC_DCKCFGR does it only effect the apb1 and not apb2 timers cause the way it describes this bit it acts like the apb2 can be times 4 because it says PPREx so 1 or 2 but on cube mx im noticing when u enable t...
Hi, i can definitely use a push in the right direction as i am really stuck on this one. Goal is to push new firmware onto a STM32F446 via the built-in bootloader. For this i have connected two MCU's on a CAN bus, the receiving one is a STM32F446. I ...
I'm having some ADC+DMA sampling problems with the H750. When the ADC+DMA is working, in continuous mode, PC2_C(ADC3_CH0) gets 16bit sampling data which is unstable and constantly jumps between 10000+ and 30000+. I guess there is a problem with the ...
Hello ST,The STM32N6 Datasheet (DS14791 Rev 2) claims that the device has 1 HR Timer and 4x 32-bit General Purpose Timers, yet the Functional Overview section does not support these claims. Nor does the Reference Manual (RM0486 Rev 1). Could you pl...
I came across a nice tutorial (8-bit data) and successfully had the code work with the STM32F103C6/8. Win11 can see it as a joystick. *** Original HID_MOUSE_ReportDesc *** 0xA1, 0x02, // Collection (Logical) 0x05, 0x01, // Usage Page (Generic Ctrl...
Hi,everyone. currently i'm trying to acces IS42S16400J SDRAM using STM32H743ZIT. but i have problem, when i write "01020304" data to C0001000 addres the data was duplicated to addres c0001080,although i didnt write anything on that addres do you guys...
Hi! I am working on a project where we are using DMA driven SPI-transmissions. I am using LPTIM1 to synchronize readouts of multiple SPI busses. The setup works when the transmissions is equal or below 128 bits (for SPI1-SPI3). When HAL_DMA_MuxSync...
I'm trying the LPBAM_LPUART_TransmitReceive with a NUCLEO-U575ZI-Q but I can't make it works.I enabled the debug by removing the init of PA13 and PA14. The MCU got stuck into an hardfault when calling ADV_LPBAM_UART_Transmit_SetFullQ() for the secon...
RM0360 (STM32F030x4/x6/x8/xC and STM32F070x6/xB) says:"The ALRAF is set to 1 if the calendar subseconds, seconds, minutes, hours, date or (sic?) day match the values programmed in the alarm registers RTC_ALRMASSR and RTC_ALRMAR"But, surely, that shou...
There have been several threads lately where the posters have seemed completely unaware of what a "solder bridge" is, and how to use it. Example: https://community.st.com/t5/stm32-mcus-products/uart-in-stm32-l432kc/m-p/689335/highlight/true#M253126 P...
