Considering purchasing the J-Link PRO SEGGER, any advice please

helloConsidering purchasing the J-Link PRO SEGGER to aid my developmentI like the idea that it runs from Ethernet and has all the advantages of using EthernetAlso like these feature of deeper and more advanced debugging and trace etc.Can any one plea...

Whether BOR is default enabled in STM32L431 controller

Hi,I am using STM32L431 controller, I would like to know whether BOR is enabled by default or we have to write code to enable the BOR. I Assume that, by default it is enabled for threshold voltage 1.7V. Please share your input on this. ​Thank you in ...

Does the STM32L0 series support the SWO viewer interface? I can't find this signal in the datasheet.

STM32CubeMx 5.0.0 update leads to firmware lock using new() operator

After updating CubeMx from 4.27 to 5.0.0 I ran into trouble regarding the newly created module syscall.c:compiler error (had to switch the C++ dialect settings from "-std=c++0x" to "-std=gnu11" to fix it)but firmware is now not running - it stucks in...

No scroll bars in STM32MX 5 GPIO config?

First let me say I love CUBE. I make it a point now to use ST parts when ever possible just because CUBE makes things so easy. However, the last two projects I worked on had CUBE (OK, the code generator firmware under CUBE) bugs that took a while to ...

Using same GPIO_PINs as input and output while the port is configured as "OUTPUT PP" AN4666

I'm trying to do something similar to what have been covered by the application note AN4666 "Parallel synchronous transmission using GPIO and DMA" but now I'm testing without DMA functionality. Right now, I can write/send data to GPIO port using: GPI...

Bad math continues to persist

I've complained about this before, but it is still broken and shows lack of grasp.STM32Cube_FW_L4_V1.13.0\Projects\NUCLEO-L432KC\Examples\RTC\RTC_LSI\Src\main.cThe following code results in answers which are a multiple of 8, and loses precision which...

Exit STOP mode only works with WFE and not with WFI

Hello, i use RTC to exit STOP1 mode (tick disable) , the only way is to call HAL_PWREx_EnterSTOP1Mode(PWR_STOPENTRY_WFE);HAL_PWREx_EnterSTOP1Mode(PWR_STOPENTRY_WFI); doesn't work.Have you any idea why ?thanksregards
