New possibilities for the ultra-low power segment!

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...

Connecting STM32F7 FMC with SDRAM and 8 bit data bus

When using a 16 bit data bus, the STM32CubeMX generates outputs for FMC_NBL1 and FMC_NBL0 that connect to the SDRAM DQMH and DQML pins. If the STM32CubeMX is configured for an 8 bit data bus, there is no DQM pin generated, although the 8 bit SDRAM h...

STM32H750VB

Hello,I want to ask if it is possible to drive TFT with FMC (Flexible Memory Controller), our TFT has only MCU interfaceI think EMwin has no option for MCU interface at STemWin_CM7_wc16 library.We used same TFT with STM32F207 by using FSMC .If its n...

Resolved! Generating specified number of pulses using PWM

Hi All,I am trying to generate required no of pulses using PWM. This is to implement to control stepper motor with position control. I use HAL_TIM_PWM_Start_IT to start pulsing and count the no of pulses in HAL_TIM_PWM_PulseFinishedCallback. I notice...

I want to print out 5 waveforms in 1us time.

I want to print out 5 waveforms during 1us.So, I printed out 5 MHz period PWM from TIM3.We tried to change the duty cycle of TIM3 to zero at interrupt time by running a 1 MHz timer counter on TIM6. However, it was confirmed that TIM6's 1 MHz timer co...
