STM32F411 Discovery can not power the external led using 3V pin.

Hello everyone. I have a stm32f411 discovery board. Long time ago it worked fine. But now when I connect the external led with GND and 3V pin, the led is not on (the led is ok, I already test it with an arduino board). I don’t know why. Other functio...

MCU with IO bandwidth of 150Mhz or more

Hi All,He have an application that requires fast IO's switching. More specifically, we have a 16bit 200Msps parallel DAC and we are targeting to load a waveform from either flash memory or external memory and output the bits for the DAC. Using an FPG...

Serial routine fails for some reason

STM32F429ZIT6 - NucleoI am doing some tests with this board, it reads Encoder input in x4 mode, generates TRGO to ITR1 slave TIM1 in One pulse mode when it reaches TIM2->CCR3 value and updates Encoder counts and number of triggers every 15 seconds on...

I have an STM32G0C micro when placed in stop1 mode draws about 7uA. If I enable any gpio as input interrupt, the stop1 current draw is @700uA. Seems maybe the AHB is activated to sense input voltage changes. Is this increase in current expected?

I'm following this tutorial: https://www.youtube.com/watch?v=WgsXMVZfoO8&list=PLnMKNibPkDnG9JRe2fbOOpVpWY7E4WbJ-&index=7&ab_channel=STMicroelectronics And my boar cannot conect to mi phone.

The connection green led indicator doesn't twinkle, it is alway on and I can't see the nucleo in the ST BLE Sensor app. I suppose that the problem is with the CPU 2. I was debugging the code and it nevers reaches the function APPD_EnableCPU2( ); beca...

"locked out" from Nucleo-L4P5, cannot erase or program

I have a Nucleo-L4P5ZG board and I cannot use it.Flash download in CubeIDE always fails because of an error erasing memory.I then hooked it up to STM32CubeProgrammer, but the problem persists.Independent whether I try to erase an individual sector or...

STM32F7 CAN BUS Rx Interrupt not triggering

PREMISE: I have experience with other communication protocols but very little with CAN so I am not completely sure how to set the prescaler and other parameters.GOAL: I want to read a sensor (namely the airspeed sensor ASPD-DLVR) through the CAN BUS....

ADC interrupt never gets called

Hi, i'm struggling with this piece of code here:int main(void){ UART2_Tx_init(); ADC_interrupt_init();     while(1){   }   }   /***********ADC***********/   void ADC_interrupt_init(void){ RCC->AHB1ENR |= (1U<<0); //GPIOA clock enable GPIOA->MOD...
