Trigger SPI using Timer
I'm using STM32H723ZG I want to know if a Timer's update event can trigger SPI transfer without any software interrupts.This is the problem

STM32N6 External Loader
I'm currently developing an application with custom hardware using the STM32N657I0H3Q and MX25UM256, I can't seem to find the source files for the existing STM32N6 external loaders which use the MX25UM512. Any links to this or resources to point me i...
Resolved! STM32H742AG Flash Erase Bank 2 issues
Hello,I am trying to erase flash bank 2 and then re-write with an incoming application. This appears to work that when I read back some of this sector it's changed to 0xFFFFFFFF, however when I restart or connect with STLINK it reads out as 0x0000000...
RTC Oscillator not stable
Hello,In one of our new PCBs we use a STM32L476VET6. For the RTC we use an external Oscillator (shown in the Picture)The drive power is set to the highest level.In our setup, the RTC only works at room temperature and with no probe connected. As soon...
USB CDC device not recognized
Hello everyone. I am using an F411 and I cannot figure out how this is supposed to work. I enabled USB_Device in middleware, enabled USB_OTG_FS, and set up line encodings based on the default STM32 example, but when I flash STM (or step through with ...
Resolved! Configuration preservation from Boot to Application transition
I have noticed that in my Application project there is no SystemClock_Config() generated by CubeIDE so my guess is that these settings should be inherited from Boot stage. If that is the case, should I also not initialize XSPI interfaces, memories an...
Resolved! Omit C29 and L1 in STM32WB55RGV6 SMPS design ?
Hello everyone,I’m working on an electronic design using the STM32WB55RGV6, and the final product cost is very constrained.I have a question regarding the SMPS components, specifically the capacitor C29 and the inductor L1 shown in the reference desi...
Can I use an internal RC oscillator to achieve an I2S master clock for a 48kHz sample rate ?
I am trying to develop I2S master using the NUCLEO-L433RC-P, but struggling to achieve a master clock speed for 48kHz playback.The I2S audio is working (using a MAX98357A I2S amplifier) and the master clock speed needs to be 12.88MHz (i.e. 48kHz x 25...
NUCLEO-U031R8 – Unable to Read/Write UART Registers in Interrupt Mode
Hello everyone,We are developing a custom UART driver for the NUCLEO-U031R8 board where both transmit and receive operations are handled through interrupts (no HAL/LL blocking calls). However, we are facing a major issue: we are unable to reliably re...
