STM32 MCUs Products

I'm going crazy, look at the photos: if I move the SWD CLK connection in one point of the breadboard the connection works, in another it doesn't! The chip is a STM32L412KB, I tried to replace it but nothing! I also replaced the ST-LINK but nothing yet.

Multiple ADC sample with different frequency interference

Hi,everyone.I'm use NUCLEO-L496ZG platform.ADC1 sample at a frequency of 5M,ADC3 sample at a frequency of 12.8K(PWM trigger).when only run ADC3,ADC3's waveform is normal.when ADC1 and ADC3 run at the same time,ADC3's waveform has a lot of interferenc...

Can not able to transmit continuously

Hi,i am transmit data through can protocol in stm32f103 controller in the while loop and i am doing doing adc and display data on 16x2 lcd so i found that doing this my can transmit is transmitting only 4-5 times amd then stop so i want to ask what c...

Timer in Encoder Mode Interrupt via Output Compare

I know, I'm repeating an age old question, but has there been any updates on generating an Interrupt when using a Timer in Encoder mode? I know, that the Interrupt doesn't fire in Encoder mode, but I read in this one thread, that it's somehow possibl...

Ordered MCUs have shorted pins

Hello. I recently purchased STM32F405RGT6's. However, out of package and on all of the IC's that I received, I discovered shorts between pins 17 (PA3) and 18 (VSS), which I do not believe should be shorted. I have a few STM32F405RGT6's that I purchas...

[SOLVED] --- Encoder very easy code ---

Here the code to read encoder.unsigned int Enc_dir; unsigned int save_a = 0, save_b = 0;       void BSP_Encoder_Init() { GPIO_InitTypeDef gpio_init_structure;   __HAL_RCC_GPIOF_CLK_ENABLE();   gpio_init_structure.Pin = GPIO_PIN_8; gpio_in...

STM32F746 Flash Memory Organization?

The datasheet for the STM32F746VET shows that it has 512k bytes of Flash. But the Reference Manual for the STM32F74xxx shows 1Mbyte of Flash (sectors 0 thru 7). Do we just assume that sectors 6 and 7 don't exist? This seems a bit vague.
