i am driving STEPPER MOTOR using TIMER in PWM mode use interrupt for counting PULSES now how can i accelerate motor slowly(acceleration time 200ms) then running at set speed?acceleration time(ex 200ms) is variable how can i do it? Can iuse dma for ve...
Hi, I use 16-bit ADC to collect small-value ac signals, and then use USART to transmit them to the computer for reading. The following figures are the result I read. The amplitudes of the two signals are respectively 20mVpp and 100mVpp, and we can ...
Hello guys, first, i would like to thank you about this forum i used a lot and got good suggestions and i learn a lot from you.About my problem:I checked a lot in the internet and see others that had the same problem like mine, but didnt find any wit...
I have generated minimal code using cubeMX that i enter stop2 mode and never wake up.i added some functions to decrease power consumption and tried to combine between them in order to see how the idd measurements changes.among the functions:killing t...
I have a STM32L433 driving a FDA802 using SAI in I2S standard mode, and it randomly swaps the left and right channels. I have compiled with a small table of interleaved data (two sine waves of different amplitudes) to try an fault find. the code I am...
I am trying to build an iap that reads a .bin file from a uSD card and loads it into the flash memory, but something is happening with the erase function. If i run this bootloader and the flash is empty everything works just fine. However, if the fla...
I have a STM32G071 nucleo and want to generate an arbitrary waveform on PA0 via TIM2-CH1.I am using the HAL_TIM_DMABurst_MultiWriteStart API: it should do bursts of 3 writes to multiple registers (ARR and CCR1).Problem is, the DMA only updates the AR...
I'm interested in motor speed control. When reading the documentation on the timer modules, it talked about having the counter value saved using a different timer or DMA. What I am wondering is can I read the value manually via an ISR and reset it to...
HiI created my own board with a STM32F411RE microcontroller. I can program it normally with a ST-Link v2 probe, the program works correctly.But from time to time when I disconnect this probe the board stops working. Can someone explain me why?On my c...
