Greetings, STMCubeIDE STM32F407G-DISC1 I am tryiny to read a stable analog signal from LM35 output pin.However, I usually read zeros.The rest of the data also make no sense.Because the data range between each other is ve...

STM32F407G DISC-1 STMCubeIDEGreetings, I am trying to send data to LCD screen by using I2C Communication Protocol. I succeed in doing it by using HAL library. Also, my current work does work in debug mode.However, I could not make it work by runnin...

Hi, STM407G DISC-1 STMCubeIDEWhen I configure PA6 pin as an input with pull-down. In a floating state, I still measure approximately 2.8V.Do I have to use an external pull-down to make it near to zero?

Hello,STM32CubedIDE, STM407G DISC1 BOARD I am trying to trigger an external interrupt by using a button connected to PA1 pin. My configurations are below; 1-) I enabled 7.bit in NVIC_ISER register. IRQN_EXTI0 is enabled 2-) I enabled GPIOAEN...

@Sarra.S Thank for your reply. I fixed it.hadc1.Init.ContinuousConvMode = DISABLE;The problem persists.

Yes, I already checked them, in HAL structured code, no-pull up, no pull-down is configured.Also, I tried to use external pull-up resistor but in any case TxE is never set.I already shared each file as public.

while (!I2C1_SR1_TXE_READ()) Code enters infinite loop in this control, TxE bit is never set. What should I do to assure it will be set?
