How to generate a timer interrupt using Arduino IDE and STM23duino ?

I want to generate an interrupt each second using Arduino IDE and STM23duino. The interrupt ISR will store an byte value. The target is a Bluepill with STM2F103C8T6.I found a lot of exemples on the web, but nothing running or compling using these to...

STM32F401RE goes into infinite loop when interrupts are enabled.

I am not sure why but the moment I enable this interrupt the debugger goes to this file and just sits there. What is interesting is the stack trace changes if there are certain functions involved but the error never changes. So I removed all the func...

Example for STM32F407G DISC1 Discovery Board using accelerometer

I would like to know if there's any example and documentation on how to use the accelerometer in this board.

Hi Guys, I'm using an STM32F401 board, accompanied an expansion board, and by a VL53L1X (people counter) sensor. It works for 10minutes then the board crashes and the only way to get it working again is by resetting the board.

Hi Guys,What I'm usingSTM32F401 board accompanied by a expansion board (X-Nucleo-53L1A1) and using one VL53L1X (people counter) sensor.ProcessI managed to flash the board and use the counter with success. To view the board USART messages I use the mi...
