Message:I have configured PA11 and PA12 pins in input mode, but they are not responding — I’m continuously getting a low level from the MCU side.For testing purposes, I configured the same pins as output, and they work fine in output mode.To verify h...
I tried to download library from https://www.st.com.cn/zh/embedded-software/stsw-stm32054.html several times but failed.When I clicked download v3.5.0, nothing happened. By the way, we network is fine. Is it forbiden to download this version?
This is a question related to SPI communication.What is NSSP mode? What does it do?Also is there any documentation that explains all parameters in detail other than this
I'm trying to use 2 timers (TIM1, TIM8) in sync.Everything works OK when using same value for both timers' ARR.But drift occurs when using two different values as ARR (i.g. 3999 for TIM1 & 19999 for TIM8).What could be causing this drift? tim.c/* TIM...
I'm trying to start a timer when input GPIO becomes high (on its rising edge), at the same time i want to pull another GPIO to low. This is time critical.I'm using an external adc which will output a ready signal, at that time i want to pull CS pin t...
STM32C071GBU6 PA2 (pin 8 on the UFQFPN28 device) is configured as ADC_IN2. What voltage can be expected when the pin is unloaded?
Hello,I have strange behavior with reset, with reset pin, NVIC_SystemReset() or then IDWG fires the MCU just stops and do not restarts with debugger connected or without, when debugger is connected and toggle reset there text is displayed what addres...
HIUsing stm32f303veh6.Changed the option bytes with the CubeProgrammer. 2.20.0 to override the BOOT0 signal. ( its floating )nBOOT1 - > uncheckedBOOT_SEL -> unchecked I see that the address on start is 0x1FFFF.. and my FW on flash does not run. For d...
Hello,Regarding the STM32N657, I'm not using the internal SMPS. My question is: Do we need to put capacitors on the 6 VDDSMPS pins or can they be left as no connect? Same question on the VLXSMPS pins... do we need the capacitors on these pins, or...
Hello Everyone,I am facing an issue with my MCU entering low-power mode.My idea is to freeze the Independent Watchdog (IWDG) counter in STOP mode so that the MCU will not reset due to the IWDG counter elapsing.From my understanding, this can be achie...
