STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
I am planning to use LED2472GQTR 24 channel LED driver for a project but MCU used in the EVK is STM32F103C6T6 which is a 32 bit MCU. My application is only driving LEDs nothing more. Any simple MCU with SPI interface around 20 to 28 pin count can be ...
--------EDIT: I added a minimal example project, 2 posts below.--------Using the WWDG on STM32L07, because I need the EWI interrupt it offers to prevent the reset in certain situatons.(Edit: orig. config code + some obsolete explanation removed. The ...
Dear comrades!I have encountered a problem while debuging my STM32H742VG project.I am falling into HardFault just after system init and do not know any reason why it is happening. I am starting my MCU with HSI clock and debugign with a STLink v2 debu...
I've just bought a STM32H747I-DISCO board and trying to blink the leds on the board (LED1 to LED4). However, when I assign these leds to CM4 core, they won't light when I use default peripheral settings of this board. CM7 core can do this without pro...
Hello! I once asked a question about ADC:("adc-functionality-in-stm32f1-stm32l15x-series")Since then, the ADC has gotten much,much better, thank you!There are even versions with 16-bit. But there is still one serious problem. This is a built-in refer...
Hi, I am a bit new to the STM32. I am trying to implement one board (STM32F7) as a transmitter and another board as a receiver. The boards should be able to communicate with eachother wirelessly. Any idea how it can be done? The data is in the form ...

i am using 6N137 high speed optocoupler but problem is op is inverted.so i required high speed (frq >= 100KHz) optocoupler with non-inverted op.or how can i get non inverted op using 6N137 ?
I use stm32f103rbt6 for bldc motor control.I config three gpio as pulldown for hall sensor, in addition,these IOs with external 3k resistors pull to 5V.But sometimes the motor halls readback by mcu are all low level.However, in fact, motor hall is go...
Hello, I'm trying to build a simple program to communicate between 2 microcontrollers using FDCAN. Im not using a transciever yet, just connecting TX of one Nucleo-G431KB to the RX of one Nucleo-G474RE, and vice-versa. Using the test modes, External...
