Resolved! Is it possible to use multiple functions on a single pin on STM32U5?
According to the RM, I think that it is possible to use multiple analog functions on a single pin. Can we do the same with digital pins? What I would need is to put a timer channel (as input) and an external interrupt input on the same pin.
STM32F103 runs only after flashing and not after that
I am using STM32f103 and Cubemx ide. I implemented small project 1 month back and that time it was working fine but now when i am trying to use same code then i observed weired behaviour.Code runs only after binary flashing and after that if i press ...
How to troubleshoot corrupted read/writes to SDRAM on STMH753 MCU?
I am attempting to interface my STM32H753 based system to a Micron MT48H32M16LFB4 512Mbit SDRAM chip through the FMC at 100MHz. The chip seems to work - but not completely according to my expectations. I have managed to write and read data to and fro...
Resolved! STM32 gpio maximum toggling speed
Hi,I my project I need to toggle a gpio pin at 200MHz or more than this.Which STM32 controller is peferable.please any one help me.thanks and regards
Resolved! ADC external trigger features in STM32F103C8T6
Currently working with a STM32F103 MCU for a power metering application.In order to have a programmable time shift between sampling voltage & current , i decided to use a PWM signal from the Timer to clock the ADCs.I wanted to kick the ADC1 at the ri...
STM32F103 won't wake-up from standby mode using RTC alarm.
MCU wakes-up from standby mode by external signal on the wake-up pin (PA0). Also, the RTC alarm does produce an interrupt when NOT in standby mode (callback function does send some characters to UART). BUT, if the MCU is in standby it cannot wake-up ...
Help please, how to debug in SDRAM with IAR?
I am developing with stm32h750.My application is storaged in QSPI Flash and running in SDRAM.I use a bootloader to move image from QSPI Flash to SDRAM and jump to image.For downloading, i made a cmd line tool to communicate with bootloader via seria...
Known issues with D-cache and FMC on STM32F7
Hi,I'm using a STM32F765 clocked at 216MHz and when D-Cache is enabled it badly affects reads from a device connected via the external FMC address/data bus (NE1, 16 bit data, 10 bit address). The following pictures show the problem (note ringing is c...
