Hello,

Software: Flowcode V10 Professional
Board: STM32F303CBT6

I have download the Timed_internal_example form Wiki, change the MCU from Arduino to STM32F303CBT6:
Simulation: OK
Compile to Target : NG

I have to say , looks there is lots of bug in the stm32 Timer Interrupt.
Below is my another post, please look at the end, still waiting for reply.
viewtopic.php?t=3275

Please pay attention and solve them.

Hello,

Yes it looks like the timed interval component has a problem on STM32 we will investigate.

For now is it possible for you to just use the timer interrupt instead. I have attached a modified version of your program as an example for you.

You will probably need to go into the properties of the interrupt icon to configure the interrupt rate.
