Flowcode Support Board

Hello!
My project on ATMEGA328 uses three PWM channels. Everything works fine in the simulator, but it won't compile and gives errors like the ones in the picture. Please help.

I've just tried compiling an ATMEGA328 with PWM and it compiles without error for me. Make sure you are up-to-date with library updates.

Also, it was tricky to see what the error is from a screenshot. In future, it is much easier to solve problems if the output is available in text (e.g. by attaching the generated msg.txt file to a forum post).

It's also very useful to attach the fcfx file too as this saves a lot of time trying to replicate a project that exhibits your problem.

If library updates does not solve your problem, please post these files here and we will investigate further.

It looks like the specific error being generated it due to the 7 segment quad component pin connections, something there is referring to PortA which doesn't exist on the device you're using.

Maybe try going through the properties and checking there isn't a hidden pin thats referring to PortA.

Hello!
Thank you for your reply. I updated the component library, but the problem remains.
Everything simulates fine, but it still won't compile.

Select the 7seg Quad component on the 2D Legacy panel then right click and select properties.
Within the properties change any pin that has Port A selected.
E.g. the top pin pin is connected to port A.0 As Ben stated port A does not exist, hence not able to compile.
