Flowcode Support Board

I suspect there might already be examples on this or the old forum.
Just some other points...

Presumably you have proved that the hardware is working? Perhaps adding a led flash in the main loop.
Are you using your own hardware design, or a development board?

You have a pull up (or down) resistor on the switched input?

I would also suggest that you keep the interrupt code as short as possible, e.g. just set a flag and then test for it in the main loop and do your printing there

I couldn't even achieve the EXTI Interrupt software simulation in the Debug - Run mode.

To be clear, only STM32F411CEU6 I have downloaded it to a standard development board(Still failed), for the others, I only tested it in the Debug-Run mode. the program will never goes into EXTI macro even when I set the EXTI active button always on and Step into it.

As you mentioned,I changed the program to use a flg in the EXTI Interrupt Macro and an LED on the main loop.
I have tried 4 boards : ESP32(OK),PIC(OK),PICO(NG),STM32(NG). 2 success and 2 failed. The program are all same except the Interrupt pin.
If some want to check, please see below attachment.

I think Flowcode developers should pay attention to this issue.
Or prove me stupid. I still think this is a good example for Flowcode beginners, and I believe there will be people who encounter the same problem as me.

Thanks for the further info.
I'm not sure what support there is for interrupts in simulation mode - one for the Matrix team.
I should be able to find some time next week to provide an EXTI example on STM32F411 hardware

Simulation on that type of interrupt is not currently supported. We will look into this and see if it is possible.

Hopefully it can be supported soon.
Looking forward to your update.

We've looked into this and the attached FCD file should allow the simulation of the pin interrupts on that device.

To try it, please download and place into the following location:
If this works ok, we will roll out the changes to the other chips in the STM32 range.

Here's an EXTI demo for the 32F411 BlackPill dev board ...

Hello.
The fix has been applied to the ARM devices and should be available via the component library update system.

Hello All,

I have replaced the replaced the file"32F411CE.fcdx", have tested the sample project "STM32F411BP_LED_EXTI.fcfx", have finished the component library update.
To be honest, I didn't find any difference, is it all be tested? Is there someone really trigger the EXTI Pin and saw it jumping into the EXTI Marco in both simulation mode and real board?
I have recorded the screen and try to show them, but it is too big to be uploaded.
Sorry, I don't know what else I can do for it. Now I am using Flowcode V10, maybe you are working on V11, but please make sure they are tested on V10 and working well.
Thanks and Wish you the best.

Best regards,
Deqiang

Step at a time...
Have you tried the demo on hardware?
It gives a short LED flash every half second.
Gives a long (half second) flash of the LED when the interrupt input is triggered.
What do you see?
