LSI frequency not stable when switching power
Hello everyone,I'm working on a project using STM32U031, and using RTC with LSI(32kHz) to calculate elapsed time, and everything working fine, the waveform of LSI output also looks great.And I need to switching power supply in sometimes, and there co...
Clarification about timing inconsistencies on G473CETx LQFP48
Hi there!I am working on a project using an STM32G473CETx LQFP48 MCU in STM32CubeIDE.I am using TIM2 to simultaneously:1.) Generate a PWM output signal using:Channel 1 - PWM Generation CH1 - Combined PWM1 modeChannel 2 - PWM Generation No Output - Co...

STM32F07- act like a dead chip.
I have a board that used STM32F07. I connect BOOT0 pin to GND via RES 10kOhm and left NRST pin open. At first i able to connect to STM32 and upload code but problem is after first time upload code (I use debug mode). It show STM is disconnect and aft...
STM32L011F4P6 can't upload code.
I have STM32L011 board that i make. I left NRST and BOOT0 open. And i try to upload code using ST Link V2. But seem like the ST link is not recognize the STM it always show "Target no device found". Can anyone help me identify the problem? Please..Th...
STM32H7 + FMC + MDMA transmits only the first halfword
Hello everybody,Im am currently trying to connect a STM32H753 to a AD7606B using the parallel interface (FMC) and got it working at some point where the CPU can read/write the data from/to the FMC but it needs a __DSB() before starting to use the rea...
Explain Output Speed STM32U575
I am working on the firmware for my STM32U575 based controller board. I cannot find in the documentation an explanation about the Low/Medium/High settings on a GPIO port. I see the bits to be set, and in MX the option for choosing the setting, but I ...
