hal_i2c_addrcallback not invoked with STM32H7
I'm working with STM32H743 and faced the problem that"hal_i2c_addrcallback doesn't invoked", it was invoked in other STM32 series such as F4 but H7 series doesn't work. does anyone faced same problem ? and if you have any clue ?
STM32L4R5 Differential Channel Issue on ADC1_IN5 (using pins ADC1_IN5 / ADC1_IN6)
On the STM32L4R5 I'm seeing unusual results reading a signal from the differential input ADC1_IN5 (Which uses ADC_IN5 / ADC_IN6 pins). When I apply an identical voltage to both differential pairs I see the reading vary with voltage, but the differen...
serial driver using cmsis ?
Hello,Is there a cmsis driver for uart ? I build with stm32cubemx, but I did not find any cmsis files for any driver (I also don't see in cube anywhere we can state that we want to use cmsis driver)I also did not find it in examples of stm32cubeh7:en...
PI controller using an L432KC nucleo
I'm designing an embedded PI controller using a STM32 Nucleo board. In the PWM configuration, a 0 means 0% duty and 800 means 100% duty. The objetive is to regulate the speed of a PMDC motor, i.e, to keep the RPM under load variations. I'm not sure y...

I2C interrupt is blocked when flash erase occurs. Is this expected in STM32L452?
I'm working on STM32L452. I found I2C interrupt is blocked when flash erase occurs. I have checked that I2C IRQ handler is in RAM. The vector table is also copied and used in RAM. How come the I2C interrupt is blocked. I have gone through the flash e...
How to power a STM32F746G-DISCO board from the CN6 VIN pin ?
Hi,I'm trying to power a STM32F746G-DISCO board from the CN6 VIN pin.I have a voltage regulator that output 11VDC current.The screen turns on but the program never start and LD6 and LD3 become red after a few seconds.I measured the current between GN...
