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...
How are parts purchased from www.avaq.com?We want to purchase the stm32 series, this one https://www.avaq.com/chip/stm32l010f4p6Looking for some advice.
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 ...
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...
Hi, may i know how do i declare the debug pins (PA13, PA14) as input pins after programming?
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 ...
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.
