Hi, I have configured my STM32H563AI CubeMX-project to use "JTAG with Trace Synchro(4bits)" and assigned the corresponding pins. Also, I explicitly activated the corresponding registers in DBGMCU and DCB by adding: SET_BIT(DBGMCU->CR, DBGMCU_CR_TRA...
What is the process to use the ADC on STM32L152rct6 to wake up the micro from Sleep?
Hey everyone,I'm currently working with the STM32H7S78-DK.I'm trying to set up an external memory loader project, executing code from external memory with XIP, while also partitioning out the SDRAM in a few different addressable chunks in the memory ...
Hi,while I'm configuring the FMC interface i come cross this memory map and i couldn't understand it. Does the FMC SDRAM Bank 1 have 4 possible regions? if yes, does SDRAM Bank 2 have the same option.what about the External Memory region, are those f...
I am confused about which clock(s) drive the timers. In the reference manual is says the APB clock drives the timers but there are 5 APB clocks. Also, in STM32CubeMX there is a "Timer Group Clocks". What clocks drive which timers or is the one dri...
I have questions on the System Memory Boot Mode of the STM32G070CB MCUSetup:Access the System Memory Bootloader Mode every power cycle. Hence, I updated the Option Bytes as below:The MCU contains the Application image only; it does not contain a cust...
I am trying to detect both rising and falling edges on a GPIO input using EXTI.I am using a STM32H755 (144 pin) - SYSCLK is 400MHz, but I am using the CM4 core, so the CPU clock is 200MHz. APB Timer clock is also 200MHz.The signal I am monitoring is ...
How to unbrick a C0 if user firmware reprograms SWD pins as IO? Because by default BOOT0 pin is disabled so there's no way to enter the bootloader unless it's enabled in OPTIONS bytes. I've added a failsafe 2 second delay at bootup before running any...
Whether the two buses can be used at the same time？ Winbond's SDRAM is used to find a high probability of reading and writing errors in SDRAM data。 but there is no problem with using ISSI. If you don't read or write to the external SRAM, it's fine。
I have compared my platforms using PDM microphones related to PDM to PCM and filtering:Platform 1:STM32H747 (Portenta H7), with SW PDM2PCM filter (and optional to add post-processing)Platform 2:STM32U5A5 with ADF filter (in MCU) or external PCMD3180 ...
