Arduino for STM32

As the handle hcrc does not init explicitly this field it is set to 0 which is not a correct value.

I've made a PR:

This PR fixed the issue

m trying to get an stm32l452re running but when i try to run my program, it fails at line 165 in stm32l4xx_hal_crc.c:

/* makes sure the input data format (bytes, halfwords or words stream)

Update: I managed to get the debugger working again and found that my Sysclock_Config() function was not being called on startup since it was being missed from compilation. Adding #include "Sysclock_Config.h" (which contains the function definition) the correct initialization code now runs.

Looking at the Nucleo L452RE definition, by default Serial is mapped on SerialLP1 using PA2, PA3. Your code does not change this as you simply re-set the same pins so it will always use the LPUART1.

Which board?
I'm using a home made board with an STM32L452RE onboard which was working great with previous versions, but now doesn't want to work after upgrading to 2.4.0.

Why boards.txt is empty?
The local boards.txt is empty because i don't know what should be there.

Why enable all HAL ...

Hi, i'm trying to make a short program that prints to the serial monitor i have connected to an stm32 based board. The problem is that when i re-map the Serial (SerialLP1 is default) to use different pins, the serial monitor doesn't receive any information.

I have a DHT11 setup with its Rx ...

Update:

I've configured the SDMMC clock to be 8MHz and starting with a clock div of 78 to bring it to 100KHz for initialization but it doesn't seem to affect it.

Hi,

I'm currently working on a project that uses a MicroSD SDHC card as its storage.

At the moment i'm having problems with initializing SD cards. Sometimes the SD will initialize ok but other times the same cards won't. I've pinned the bug down to a particular line of code but I am having no luck ...

Hi!

I've made this Ring Buffer to use for spooling data between devices that run at different rates.

Single items can be appended to it, and then large chunks can be read at once. It's designed to be used with the STM32SD card, which allows large block writing with DMA access.

To use it with the ...

Looks like i must try to use DMA instead of polling.

Does anyone know how to switch STM32SD to DMA mode?
