Hi,I am a beginner and I want to generate a 50Hz square wave on STM32F407 on Keil UVision4Please mention libraries etc that are being used and if you can how to add them to Keil UVision so it doesn't give an error.
Hi STM32 TeamI can not find STM32F402RCT6 in cubemx or ST website. but, i can buy this chip form szlcsc.com.How can i develop this chip. It is discontinued or a transitional type? (only see a STM32F4 value line or more message)
I am faced with an interesting problem. The code I have seems to run only after I press the reset button. If I somehow remove power, and put it back, it will not run until the reset button is pressed. HAS ANYONE ever had this problem ?All my power r...
Hi Madam/Sir,We recently developed a custom board using STM32H747. The designs and schematic were based on Portenta H7 and the disco board. We received the board from PCBWay and confirmed that hardware-wise, it's okay and was proven electrically corr...

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...

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...
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...
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...
