Why HAL_GPIO_Init returns void instead of HAL_StatusTypeDef ?

I notice that almost all peripherials return HAL_StatusTypeDef but GPIO not. Why?

Resolved! STM32L152 is now NRND (since wehn) - what do us instead STM32L552RE is there a compare sheet ?

Since when is STM32L152RE LQFP64 NRND?From the looks best pin compile etc. would be STM32L552RE is there any overview for doing this transition. Else I would need to do detail compare my self but as these MCUs seem to be in one line I was hoping ther...

Where are release dates of MCUs are stored

Would need release dates for:L433 - guessing from searching around 2017L152 - guess 2015L552 - guess 2018L072 - guess 2016has anybody a way to find out or the data? Thanks a lot

STM32f746 switching static IP to DHCP in run time with LWIP FREERTOS

when I press an external interrupt button, I want to switch to static IP, press again want to switch to DHCP, how can I get this? because in CubeMX it just defines once for LWIP_DHCP macro and how can I use this for static IP or vice versa ?

STM32F429DISCOVERY, STM32CUBEIDE 1.12.0 I've created a class for a communication packet. It has global scope. Upon instantiation, the code hard faults.

If I comment out the instantiation, compile and run, then uncomment the instantiation, compile and run, the code will work fine from that point on. But it will not run without hard faulting unless I do the comment / uncomment thing. Here's the code f...

Executing the __HAL_RCC_WWDG_CLK_ENABLE() function immediately resets the CPU.

I enabled WWDG on the MX and there were no other settings. MX_WWDG_Init(); As the function executes, the CPU resets, and when I look closely, I see that __HAL_RCC_WWDG_CLK_ENABLE(); As soon as the function runs, the CPU is reset. What should I do?Bel...

Hello,Didn't found a better way to ask this question elsewhere.I was registered to watch STM32 Innovation live on March 7, but I didn’t have enough time to watch it completely.I tried to register again on this page: content.st.com/stm32-innovation-li...

How to transmit data using RS485 with uart?

Hi everyone,I'm trying to transmit and receive data through rs485 with uart. Using Uart with DMA in normal mode and referance from this project. https://controllerstech.com/rs485-module-and-stm32/However, in this project there are 2 different stm. I ...

Current consumption in low power modes not as per data sheet

Using Stm32l4r5zi-p nucleo board current consumption is not matching with datasheet it is much higher like 130 -200 mA higher let me know any idea to reduce the current consumption
