Question about STM32f429 FMC SDRAM Clock Configuration
HiI want reduce fmc clock for my sdram board below HCLK/2 or HCLK/3,how can i do if possible?i don't want reduce hclk to done this .is any ways exist to reduce sdram sync clock rate?thx :)

EXTI event. Se what event woke the MCU?
I'm using multiple external events through GPIO to wake the MCU from sleep. How can I check what source caused the event? Is there a register that I can read? What I understand is that the WFE instruction also clears the event register so I assume a...
Running code from external SRAM on STM32f429
Hello, I would like to know if its possible on the STM32f429 to run code from an external SRAM. Since no QSPI connection is available on this MCU, the alternative would be using the FMC.I was only able to find an application note (AN5188) on this top...
stm32f103xg.h IS_TIM_SLAVE_INSTANCE() bug???

Resolved! STM32F769NI: How to activate USART Receiver Timeout Interrupt (USART_RTOR.RTOF)?
I want the STM32F769NI to generate an interrupt when a pause after a received byte on USART6 was detected. I am using CubeMX and configured USART6 for Asynchronous mode with 9600 baud and to enable global USART6 interrupts and use the low level drive...
Starting with Stm32f0, where could find a document explaining step by step the programming of this controller?
The programming shall be based on the difference interface using Stm32Cube or beginning from scratch (meansing configuring the register my self).I will be delighted to get a feedbakc as soon as possible.ThksRompel
Sending ADC data from Nucleo-F401RE to Basys 3 FPGA using SPI.
I would like to use the Single Channel (ADC1) of Nucleo-F401RE with DMA .i.e store the ADC values in a buffer and transmit them to FPGA using SPI Protocol. I'm afraid the nucleo is sending erratic data to FPGA. Also I'm unable to find what is the vol...
Interfacing STM32F722VET6 With Quad Memories
Posted on June 13, 2018 at 10:35Hello,I want to interface 512Mbit or 1Gbit I with STM32F722VET6 with CubeMX . I have seen lots of option for interfacing ..Which option I need to select for below memory chips in Quad SPI Mode , Bank (s) and Why ?....
Unable to implement receive data on UART interrupt on STM32F103C8T6
I bought STM32 blue pill(STM32F103C8T6) and started learning on STM32 usng STM32CubeMX and TRUEStudio and successfully LED and UART2 transmitt.But I want to implement UART receive using interrupt but unable to do so.I have tried as per example but st...
Is it possible to monitor the program counter (PC) at runtime through GPIOs (STM32F429 MCU)?
Hi, I'm using STM32F429 microcontroller and I would like to program a subset of GPIOs for automatically shadowing the value of the program counter (PC) at every clock cycle WITHOUT interrupting the CPU activity, maybe exploiting the bus matrix connec...
