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...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
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...
Hi,I am trying to wake up the MCU from STOP mode. I am able to do so for either the UART or the GPIO interrupt but not both. It seems I have to disable the UART to get the GPIO to work but then of course I cannot get the UART wake code to work.Is the...
Hi, I want to use the simulataneous ADC reading with 2 DMA channels, in order to avoid overrun errors (which I'm having).I'm using the HAL and I'm having a hard time understanding when is the DMA buffer of the slave channel assigned. When multimode i...
Hi,I am using STM32L476VGT3. When ADC1, ADC2 and ADC3 are configured independently, everything works fine. As soon as I write into the DUAL[4:0] bits of register ADC_CCR (common control register) to set ADC1 and ADC2 in dual mode, ADC3 stops. The dua...
I'm working on a project to generate composite video from an STM32 using the high speed DACs.This requires 3 DAC channels for red, green, blue fed by DMA.Of course the red/green DMA conflicts with the blue, hence the blue output is delayed about 30ns...
