MHz frequencies on OUTPUT
hey thereI have a stm32f103 blue pill board which I wish to generate MHz frequencies on pinC13.I have used TIM1. it starts and interrupts and on each interrupt I toggle PC13like sovoid HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim) { if(hti...
Help with debuging a for statement in BluePill
Hi, I'm using a base64 library to convert my data to my base64 on STM BluePill. everything works fine, but after 5 minutes i receive an imprecise data access violation hard fault error on a for statement. i'm using main loop to run my code every 1 se...
Resolved! Does micro detects low power?
hey there I have a question: can a micro, say stm32f407 detect low power? for example is there a HAL function to indicate VDD lower that 3.3v?(this way any time that power is going, I can for example save everything before power off)
How to use the STLink BRIDGE API - UART bridge?
I want to use the STLink BRIDGE API and setup a C++ project. So far the GPIO worked fine, next I want to use the UART. I found the following Warning in the docu: "UART "bridge" is not supported on the STLink USB bridge interface. This functionality i...
Internal temperature sensor shows big offset at temperatures > 50°C (STM32G474VE). Is this common knowledge and if so is there some form of formula to correct this?
Setup:Using ADC1 with an ADC frequency of 50MHzSampling time of internal temperature channel = 640.5 cycles = 12.81µs (> minimal sampling time of 5µs)Conversion triggered every 1s by softwareUsing injected channel since regular channel conversion is ...
Better clock output (instead of MCO)
Hello, In my design I would love to variate frequency to camera sensor. I did this in the past with MCO, but it is giving me very large step, so I can't place camera to any frequency I want, usually HSE, or PCLK/4 or 8.Can I use SAI interface and ded...
Is there a way to debug and run a program on a Nucleo-g431kb if I don't have an st-link?
Hi, my tutor gave me a Nucleo-g431kb to practice with. I tried running a code on it with IDE-cube but the debugger alerted me that the st-link isn't connected. I don't have an ST link, but my tutor says that I don't need any.I'll add that the red LED...
STM32U5 Enabling CLK for GPIO Port resets MODE Register to 0.
Hello,I have a problem with STM32U5 with TrustZone enabled. I use standard startupfile and have a simple init Routine:int main(void) { /* SAU/IDAU, FPU and interrupts secure/non-secure allocation setup done */ /* in SystemInit() based on partition_...
