I'm working on generating two different trigger signals: one at 60Hz and another at 600Hz, using three PWM signals on three GPIO or timer channels. I attempted to use slave trigger mode for synchronization, but I'm encountering a phase shift in the P...

Hi everyone,We recently purchased a NUCLEO-WB55RG Dual Core EVK for R&D purposes. We later realized that in the STM32WB55CGU6TR MCU, the Cortex M0+ core is dedicated to BLE. Is there any possibility of toggling GPIO on the Cortex M0+ core? If so, can...

Hello,I am currently working with the STM32WB55CGU6TR MCU and using an RTOS. I've created two threads:PWM Thread: This thread generates PWM signals using the GPIO toggle method at frequencies of 60Hz and 600Hz.Read FIFO Thread: This thread reads data...

HI ,I am trying to flash the STM32WB55CGU6TR using i2c bootloader mode.I can successfully get into the bootloader mode and able to read the bootloader version.But while performing the Erase operation its get failing(Time out Error).I am writing the b...

Hi @STTwo-32 ,Could you share your steps on how you erased MCU

What does that mean? Fix it in CubeMX and re-gen the code. Or hand-edit MX_TIM2_Init() as a quickie test and THEN fix it in CubeMX.> I modified the prescaler value to the 31 later still its not fixed the issue WAIT - You are using TIM2 as BOTH the ...

I am waiting for the solution as earliest as possible @Sarra.S

Hello @Bob S ,Does it mean that changing the prescaler to 31 will make it work? I modified it later, but there is still a phase shift between the two timers' PWM.

Hello @Bob S , Thanks for the reply,The phase shift between the timer1(three channels ) and timer2 singlechannelAre you starting or stopping the timers to toggle your "CAM_TRIG" signal? A)Yes i am starting the timer base once and PWM like belowI ...
