Sensorless bldc motor controller six step trapezoidal control
I have implemented a sensorless, six-step trapezoidal control with feed-back as zero crossing detection using back emf with the help of ADC on the nucleo-G431 board.The BLDC motor is A2212/13T, 1000 kV.Without a propellor, the motor is spinning, and ...
Resolved! stm32l431rct6: SD detect pin question
Sorry, are there has a pin call or used for SD_detect in Stm32l431rct6? I can not find in STM32L431xx Datasheet - production data. These has no mention.I do not know which pin(SD-Detect)should i choose for GPIO_Input of the FATS.
Resolved! On STM32C0, is SRAM preserved in Sleep mode if RCC_AHBSMENR.SRAMSMEN=0?
Hello,In STM32C0 RM0490, section 5.4.16, the RCC_AHBSMENR describes the bit SRAMSMEN which can be used to disable the SRAM clock during Sleep mode to save power. We will be using the STM32C0 in a low-power application and I was wondering if the SRAM...
Resolved! Timer input capture interrupt fires over and over - Not a late flag reset issue (probably)
My input capture interrupt is fired over and over again. But when i put a breakpoint in the interrupt, and resume from it, it does not happen anymore.Timer setup: // TIM 3 Inputs (Pedal rot - PB5 / Torc PWM - PB1) my_GPIO_InitStruct.Pin = GPIO_PIN...

Resolved! Starting a new design, looking for device tree source
We are starting a new design using the STM32H743 and we were hoping to find device tree source description of this MCU. Does anyone know if this is available?
Resolved! USB Bulk XACT Error
I'm creating a new USB device with a custom USB class on an STM32F779NIH. We have previously developed a fully operational device doing the same thing with USB full speed, now we're trying to do the same with USB highspeed using an external ULPI. I'...

Resolved! STM32L496QGI3 Vbat pin connection
Hi, Can the VBAT pin on this part be left floating? I currently have the pin disconnected. Or should it be tied to VDD or GND in order for the part to function properly? Thanks,
