SysTick_Handler() function isn't called in a project based upon the STM32G070CB mcu (48 terminals). However, with the STM32G070RB (64 terminals (NUCLEO-G070RB)) there aren't any issues. I found this workaround from 3 years ago (almost 4):https://comm...

Hi!I'm looking for a uC that:It is Cortex-M0 or M0+,It isn't a Low Power device (L series) (no need to include Shottky diodes, and my app will be power hungry)It has internal EEPROM,32 <= LQFP <= 64,It has 20+ free pins,and the most important thing: ...

I've created a new project and the IDE has stuck in the "Please Wait For Clean Up" state for more than an hour, and I cannot cancel it! Should I wait for another hour or should I kill the process and then lose all my work in the workspace?

Hi, I need to use the MCP79410 rtc (or alikes: DS1307, PCF8583, etc) but the STM32CubeIDE I2C seems that can't handle the read/write protocol for these devices. For example, as the below image shows, one needs to send the control byte (writing) follo...

Hi,I'm using the internal EEPROM bank 0 for the STM32L073 chip located at 0x08080000 (as per the user manual). After writing my data (less than 1K; and bank 0 has 3K capacity) and trying to enter into debug mode, system refuses to do so:(BTW: such l...

UM_6.3.1 says that SWCLK has a pull-down resistor:However, I've done a discovery: without the workaround the register SBC-VTOR is zero when reaching the main() function:With the workaround such register takes the value 0x8000000:

Hi,I didn't understood the issue.A fresh HelloWorld project created with the CubeIDE for the STM32G070CB mcu don't trigger the SysTick interrupt. The system_stm32g0xx.c file is common to STM32G070CB and STM32G070RB (NUCLEO board).It seems to be for ...

"Why is the mapping wrong in the first place? Issue with BOOT0 floating or BOOTx option bytes?"I have no idea. This is a fresh project ("Hello world") created completely in the CubeIDE, featuring the STM32G070CB mcu (48 terminals); the Systick interr...

BOOT0 is shared with SWCLK, and as I'm debugging with a ST-LINK/V2, I didn't populate its associated components in my PCB, as shown:Which component should I need to place? Maybe I'm thinking in that SWCLK pulls correctly BOOT0 (6.3.1 from the UM say ...

SysTick_Handler not called, STM32G070 (and 2024 release)

Help me selecting the best microcontroller for my app

CubeIDE cleaning up has taken one hour, should I wait for another?

Struggling with I2C and the MCP79410 real time clock protocol

Can't enter into debug mode after writing to the STM32L073 EEPROM memory; mass erase solves it.
