Hi,When I write RTC_init() function in code which defined by stm32cube, once powerup, system goes to a hang status, after hard reset, chip works correctly... RTC clock set to LSI when I comment RTC_init(), system works properly even, when power up a...
But when I remove power (with the 3V battery still connected to Vbat) the date/time values freeze. That is, they remain where they were when to power was removed. How do I make the RTC continue to run during power down? Any help is appreciated.
I am using the ST-LINK which is built onto/attached to the Nucleo-F767ZI in order to connect to the MCU and interact with it.I am trying to use SysTick but am unable to enable interrupts with it. Everything else appears to work as it should.I initial...
The first step succeed and I'm able to ping my Nucleo H745ZI-Q.Next step would be creating a TCP connection, this doesn't work because of some memory related problems.Calling echoclient_pcb = tcp_new() gives me back a NULL./** * @ingroup tcp_raw * ...
Hello,We are developing a product that uses an STM32, and we are wondering where we can find details about, or if it's feasible to create a customized firmware update tool for customers without extensive development time. We have no problems updating...
Hi,I have a new project which should use only parts with life time of around 10 years. Where can I see on ST's website these information for a MCU?
Hi. I realize this may seem simple to some of you but i realy want to undestand this as easy as it is possible. In STM32 (for example) there is a bit called STKALIGN. If this bit is set stack is align to 8 byte instead of 4 byte.How can i see differ...
Can anyone tell me why the value of 'c' here should be NaN ??On other platforms I get the same result for 'a' and 'c', as expected.#include <math.h> float a = atanf( -1.0f ); // returns -0.785398185 float b = -1.0f; float c = atanf( b ); // retur...
good afternoon.I was gonna drive an eMMC flash memory ( something like https://www.samsung.com/semiconductor/estorage/emmc/KLM8G1GEND-B031/ ) with my STM32f407IGT6.I don't know if I can access it through the SDIO peripheral or not. it is mentioned in...
