It's my first time on a project where I need to consider "high-speed" signals, I read up on it but I am not entirely sure if I even need impedance or length matching here.I want to add external SDRAM to my stm32H7A3ZI MCU running at up to 280MHz via ...

I need to expand my STM32H7A3ZIT6 MCU's RAM and FLASH memories and since I am using a lot of peripherals and would like to avoid the rather complex routing process of the FMC, I am trying to keep the number of pins I am using low thus, I looked into ...

I am using an stm32c011 MCU and want to put my device into standby mode and then periodically wake it up (every 30s or so).I have seen guides which use the RTC to do that, but cube mx doesn't show me a WakeUp option on my RTCAm I missing something or...

I have created my first PCB with a STM32C011F6P6 on it, but I am not able to measure a GPIO I set high from my testpoint.I am setting PB6 high the following way:I flashed the code to the MCU via the cube ide and it told me that everything went fine.T...

I have made a PCB with the STM32C011F6P6 on it and am trying to program it via an ST-LinkV2. While trying it out yesterday, it connected just fine with the cube programmer. Now I am trying to do the same thing again, but both the cube programmer and ...

I edited my original post to include it.

To clarify, I mainly need to expand the RAM of my MCU for frame buffers for quite heavy GUI. This makes me think that OctoSPI might be too low throughput for it.

Oh right, thanks!

Would the idea behind this basically be to set up the IWDG to a certain time (e.g. the 30s) and then not update it to let it reset the system after the configured time?

Thank you, I was looking in the datasheet which was the wrong place :)

FMC to connect external SDRAM. Do I need length or impedance matching?

Stm32 Octospi vs FMC for extending RAM and FLASH

How to wake up from standby mode?

Setting GPIO high does not work

Can't connect to the MCU via STLinkV2 [ST-LINK error (DEV_CONNECT_ERR)]
