I'm intending to use PC13 as an output to drive the onboard LED, but at some point in my program the PC13 pin begins outputting a 4.4 khz signal with pulse width that varies from 0% to 100% back to 0% and keeps repeating that pattern at approx 4 Hz. ...
What is the difference between STM32H743ZIT6 and STM32H743ZIT6U?
I have checked the PIN they connected in the correct order and on the correct pins. I have checked the GSM module on hyperterminal and it is functioning as intended. I am using the HAL drivers and Kiel IDE.I am trying to get the response from the com...
Hello,As far as I understand, I2C access with STM32H7 supports only 8-bit data.But we need 7-bit data. Is that possible ?Thanks
Try run i2c1 in master mode. After set START bit both SCL and SDA lines goes LOW and remain until reset peripheral.
Hi all,I'm using STM32L486 and my application needs to enter STOP MODE 2 in certain conditions. Every time it will enter STOP MODE 2, I'd like to set an RTC alarm to awake the MCU in e.g. 24 hours or 60 mins (it's just a configurable time known a pri...
Hi,I was looking through the supported boards and chips for the NUCLEO-H755ZI-Q, and could not find a right file.Has anyone in here made their own they would like to share?I'm using CLion with OpenOCD for development.Best regards,Tero
Hello, I am getting data in decimal format and to need to convert it into string.So how can i do it?
MCU:STM32F446RCT6Accessing an I2C device from the MCU may cause an I2C access error.It looks like the last bit of data is missing from the MCU.As a result, access that prevents the device from returning an ACK stops halfway.Attached image "I2C_OK_NG....
I am using the STM32L433 RTC in periodic wakeup. i have initialised the rtc and it does interrupt once, but never interrupts again. i suspect the ISR rouitne is not clearing a flag some where. i have seen many comments relating to this but no definit...
