Interference caused by the STM nucleo h743 board even with the default blinking-led program?
Hi, I'm using a STM32 H743ZI nucleo board as a platform for implementing battery BMS. I have been struggling with a interference on my setup which is distorting the voltage and current ADC measurements. I have been debugging the source of this interf...
This test is to control the timer with a timer.STM32F405RG. This text is translated by deepl.
Set timer 6 to 3 seconds. Set timer 7 to 1.5 seconds.Timer 7 restarts Timer 6, so I don't think it changes the variable o in Timer 6, but the variable o changes. Is there a problem?I have confirmed that timer 6 is stopped by HAL_TIM_Base_Stop_IT(&hti...
Resolved! I want to make some delay to the microcontroller based on the number of clock cycle. What API can I use it?
I'm trying to control the timing of ADC for best performance.So, I want to give exact delay based on the number of clock cycles. However, I don't know what API should I use to give delay.Right know, I turned on TIM16 and I know how to get timer like ...
Reset pin goes down every 400ms for 50us
Hi,we have problem with our custom designed board. We are using STM32L011F4P6 MCUs and some of them behaves very strange. After reset, every 400ms for 50us, reset pin (which is internally pulled up), goes down. We don't known what causes that behavio...
make: *** [Core/Src/subdir.mk:34: Core/Src/main.o] Error 1
Hi, I am a newbie for STM32 after activating all my peripheral libraries I try to build my code but I get the following error:make: *** [Core/Src/subdir.mk:34: Core/Src/main.o] Error 1"make -j4 all" terminated with exit code 2. Build might be inco...
STM32F777 SPI Ports VIH Levels
Hi, I am using STM32F777, can you please help where i will get VIH voltage level for SPI Ports in datasheet?Please help
STM32F479II wakes up immediately from first standby if RTC time was set.
The STM32F479II is set to standby mode and activated by PWR_WAKEUP_PIN1. This all works. But there is one situation where it wakes up immediately. The next standby works however.How to reproduce: Power Cycle -> RTC has no battery thus date and time i...
Resolved! I recently ported my STM32F413 (run at 100Mhz) application to a STM32H7A3 (run at 280-Mhz). But my DSP routine does not run 2.8x faster. Anyone has any idea how this happened?
I measured the time took to run a length 127 Multiply–accumulate routine by togging a GPIO pin before and after the arm_dot_prod_q15() routine. And then I can measure pulse width by a scope. It was 7us on the STM32F413 and 6us on the STM32H7A3.
