RTC calibration for temperature variations
Are the steps followed for RTC calibration the same for crystal and temperature variation?How is the calibration register value selected for temperature variation?

RTC Calibration
I have selected the RTC calibration as 512Hz. Will I be able to perform RTC smooth calibration if my frequency obtained on the RTC calib pin is beyond the range 511.75Hz - 512.25Hz. How do I calibrate the RTC beyond this range ??
Resolved! HAL_FLASH_Program does not support programming bank 2
When trying to program the STM32L4P5RE, I get an assertion failure when trying to program the second bank like this:HAL_FLASH_Program(FLASH_TYPEPROGRAM_DOUBLEWORD, address, data)This call fails if my address is in the second bank `0x08080000`. Looki...
STM32H563 DMA Issue
Hi, I'm trying to implement read ADC1 value triggered with TIM6 then write it via DMA(GPDMA1 CH0). I created CubeMx project and generate code accordingly (Using LL driver). But I can't enabled DMA channel. Is there any code example about it?
Resolved! STM32N6 H264 Video Encoder ASIC datasheet / manual
Hello folks,I am investigating the Video Encoder on the STM32N6 and have been working through the reference project (VENC_SDCard_ThreadX).The user manual (RM0486) is very vague on detailing the Video Encoder, and lists over 100 pages of registers whi...
Who Sets the BFB2 Bit After Option Bytes Erase in STM32G4?
Hello, I am working with an STM32G4 microcontroller and noticed an unexpected behavior regarding Bit 20 (BFB2) in the User & Read Protection Option Bytes.According to the reference manual, BFB2 is a read-only bit.After performing an option bytes eras...
Resolved! CAN communication not working F407 with G431
I have two Nucleo boards that are connected with a CAN bus (Transceiver SN65HVD230). I would like to communicate with standard CAN, eight data bytes, data rate 50000 bit/s. For the F407 all TX & RX events are triggering (reused old working code) the ...
STM Part Selection for 1x USB-C PD and 1x USB-C DP Alt-Mode
Dear STM Community and Experts,we are trying to implement a dual-port USB-C design using STM parts with the following requirements:Port 1: USB-C Power Delivery (PD) Sink, 100W, no dataPort 2: USB-C non-PD Source 5V 2A max., USB 3.1 Gen 1 Data, Displa...
Resolved! STM32U575: Understanding RCC::CSR reset bits
I'm trying to understand how the CSR register works. I though initially that the various reset reason bits are mutually exclusive. That turns out not to be the case. For example, I'm seeing SFTRSTF and PINRSTF together, and also BORRSTF with PINRSTF....
Resolved! STM32H7R3. SMPS and VCORE.
HelloCan anybody explain how it is possible to power VCORE directly from SMPS output? I see that SMPS have only two possible output voltages, 1.8V and 2.5V:But VCORE accepts absolute maximum of 1.4V.So how it is possible with LDO bypassed?Best Regard...
