Hello, I am trying to create a simple frequency measuring device using 1 optical encoder and NUCLEO-F401RE board. I want to capture frequency (or period) of impulse, so I was thinking to use input capture mode and capture rising edge of impulses and ...

Hello, I am trying to record MEMS microphone data using STM32F4-DISC board. I used BSP and CMSIS-DSP libraries to gather data and calculate FFT of recorded signal. I save my recordings in static q15_t TempBuffer[2048]; and I want to cinvert this buf...

Hello,I'm testing LIS2DE12 accelerometer, trying to communicate with it through I2C. I want to make an interrupt on INT1 when some larger value is present (sensor is being shaken for example). I configured Interrupt to work on Or mode and for startin...

Hey, I'm trying to read VREFINT value using internal ADC channel for vrefint, I'm converting data from ADC to voltage and getting 1.34-1.38 V. Datasheet says it should be 1.2-1.24 V. Why my reading has such error ? I'm using 238.5 sampling time for 8...

Hello,I changed cubeIDE project structure, put files to folders to make it look cleaner, then changed project location. I managed to fix all linker errors etc. code builds and flashes, but the problem I encounter is that when I try to open cubeMx fil...

I will add variable values, maybe that would help:

I didn't initiated calibration but changing time period in HAL_ADC_PollForConversion function to max delay time seemed to fixed it, now I'm getting 1.2-1.24 V.

I'm using ST_LINK to power mcu and it is 3.3V . It might be fake chip but I quite trust shop where i bought this board. And what about mistakes in code? Why sampling time is wrong?

Yeah, I managed to figure that out by myself, but thank you, this was indeed the problem 

nope, I'm trying to measure Li-ion cell's voltage through voltage divider and it should be around 2.7 volts I get 2.4-2.8 volts and sometimes 3.2 volts for no reason. Are stm32f1's ADC really so inaccurate ? Maybe the problem is that I bought this...

Re: I'm trying to create my own GPIO API using LL library on STM32F4. When declaring GPIO port I get warning: initialization of 'long unsigned int' from 'GPIO_TypeDef ' {aka 'struct <anonymous> '} makes integer from pointer without a cast [-Wint-conversion]
