Hi,I ordered a PCB and after I had soldered all the components I noticed that in the PCB there was a connection between my SWD interface to I2C pins (PF0, PF1) and SWD pins were connected to the I2C bus. I tried short-circuiting them with a tiny copp...

Hi, I wish to produce a single pulse; lo-Hi delay Hi to Low. I am using Timer 1 PB15 which is the complementary output timer Channel 3I am using the timer in the following sequenceTimer initialisationSet the ARR and CCR3 with the followingARR = 2241 ...

Wakeup from standby with Wakeup Pin

Posted on June 25, 2014 at 13:00 I want know if is possible to wakeup the MCU(STM32F4) fromstandby power mode with only the Wakeup pin, without setting the RTC allarm. i have try this but the MCU don't wakeup. HAL_EnableDBGSta...

STM32U585 I2C SCL remains low and I2C hangs

Hi,I have two STM32L0 (slave) and STM32U585 (master) MCUs. I have no issue when Slave transmits data to Master. But, if Master transmits signal to Slave, it sends all the 9 clock pulses with address bits, but then the SCL remains low while SDA return...

stm32f103 startup io initialization problem

hello.this is the first time I've had this problem , I describe this problem next:1 the io initialization input is normal (this is the feature I want)2 when I power off and restart, I find that the same pin initialization input is not responding3 rep...

Resolved! stm32c0x use debug pins as gpio input pins

Hi, may i know how do i declare the debug pins (PA13, PA14) as input pins after programming?

Where is the interrupt on pin D1 for SDIO handled by the STM32H7?

I asked a question around this issue late last week so I don't want this to appear as a double post but I think this is more specific:To paraphrase"The interrupt concept is used to inform the host of changes in the card status using the SDMMC_D1/IRQ ...

Resolved! Calculate caps for LSE crystal oscillator

hi,i am using a ECS-.327-9-34QCS-TR with a 1.5pF caps on a STM32H743BIT6.I want to know the exact method to calculate the right value for the oscillator caps.because my RTC is off by 5mSec.

DS18B20 Match Rom command fail

Hi. I'm using STM32F030C8T6 MCU to communicate with multiple DS18B20. I'm using Timers to make 1us delay. I set my prescaler to 48-1. and I'm running on 48MHz clock. when i connect two sensors to my MCU, i can't read temperature, so for testing i dis...
