Cannot read low current consumption on STOP2 mode with my STM32L412 board (~300uA+-), but using the same code and compatible with my STM32L476, i succeed (~3uA). ill be happy to work with low consumption with the STM32L412, can any one help me with that?
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...
Resolved! Nucleo - STM32L412RB-P: How to measure IDD only through STM32 Microcontroller?
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...
Frame synchronization randomly swapping.
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...
STM32H7 HAL_FLASHEx_Erase returns HAL_OK but something extrange is happening
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...
Resolved! STM32G0 TIM2 with DMA Burst Transfer (not working)
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...
Can you read and reset Counter in Quadrature Encoder Mode via ISR?
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...
stop working when I unplug the JTAG port
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...
SPI CLOCK ?
hello , ı use stm32h750vb I m trying work spı,I set the spi as master mode, when does the master send the first clock pulse.i'm not doing any clock observation at all when i just check clock output
SPI Miso pin
hello , ı use stm32h750vb I m trying work spı,I'm trying to raise the miso pin at the beginning of the dialog, I'm wondering how you can do it.
