STM32L432KC UFQFPN32 - CK_IN pin function poorly explained/documented

I'm finding the documentation to be lacking.How does PA0 interact with CK_IN? Am I supposed to set PA0 as an Analogue Input?How is CK_IN connected to OSC_IN?How am I supposed to use this? HSE_BYPASS ?The "clock detector" in the Clock tree of the data...

USART1_IRQHandler ISR routine not been called?

Hi,I am using a STM32F407VE MCU board with USART1 as debug port. I am able to output string to USART1 but not receiving. This ISR routine never been trigger after I enter some chars from teraterm.I do believe I setup the ISR in .s file and enable ISR...

STM32F030K6 stack problem

hii am trying to make a new project on STM32F030K6 but, after i start and pause debug, a message appears : The stack pointer for stack 'CSTACK' (currently 0x20000658) is outside the stack range (0x20000048 to 0x20000448)  . and the program stuck so...

where i can find a complete example of multi channel ADC (interrupt scan) ?

STM32 MCU to MQTT server using( ESP8266)

I am trying to connect my microcontroller STM32F429IGT to CloudMQTT using ESP8266 wifi module. Our wifi module has successfully connected to the router when I tried to connect to MQTT server using AT Command it is not getting connected. It is showin...

Where to find time.h library for STM32

I'm looking to implement an RTC on the STM32F411 and with an STM32L083 and would like to use a time library (mostly) for converting between date/time and epoch time. Does ST provide these libraries or can I find them somewhere?

Timer during StopMode

Is it possible to set start a timer (e.g in a function), then enable the StopMode in the whileloop, and when the timer has expired wake up agian?

I am trying to interface TM12864H6CCGWA-1 via SPI on nucleo-L073RZ .I am unable to print anything on display. I have checked all connections , all pins are connected correctly but Its not working. Please help me.
