Compile Error (Arduino MEGA 2560)

[Brendan]

Hi Guys.

I've ported a working project from PIC to ATMEGA2560 with 16MHz Xtal for professional application, so I'm using build target option: 'Arduino Mega 2560' for the project.

However, compile critically fails with the following message:

This may be obvious to Arduino aficionados, though I'm still in the dark for what is my first AVR project using Flowcode so any clues/advice appreciated to help me get compilation over the line. Possibly a FC bug but I don't feel qualified to comment.

Once complete I'll be able to program with Microchip Studio.

Thanks in advance,
Brendan

Hi Brandon.
Any questions relating to v9 issues should be posted on Flowcode forums
Have you run a full database update?
There are two ways.
When you first run flowcode and have the options of New Project & Open project.
Select Library Updates. It will automatically have Full database selected.
If you already have a project open, select Help ribbon, Library Updates.
Change Files in-use dropdown to Full database.
You will need to use the Reload option after.
If this does not work can you post a non-sensitive stripped-down version that shows the issue?
If You cant, then you can PM me your Flowchart, if you want to keep it private.

Hi Martin.

Sincere thanks for your kind support.

I posted on the V9 forum without reply, so reached out to the MatrixTSL forum for guidance. I'm generally unfamiliar with AVR micros, though the need to switch from PIC was driven by a professional project supported by popular available off-shelf assemblies featuring this micro. The ATMEGA2560 running a 16MHz clock (albeit at 5V) features all I require, so needing to create a HEX image that I can download with Microchip studio.

I regularly update FC9 libraries from the full database (i.e. not just files in use) as it never takes too long, which includes the present project where updates were unsuccessful. I'm loathe to report a bug as I recognise that many issues can cause problems - including possible personal incompetence until I become more familiar with this chip/build project.

I've provided a simple stripped-down example project, which I'd like to keep public if I can as it may help anyone else experiencing similar issues.

Thank you again,
Brendan

Hi Brendan,

The problem occurs because of the use of USB_Serial. The Arduino Mega doesn't support it. You'll need to switch to usindg the UART component (which lets you send/receive data via the USB port too...)

Aha!

Good spot my friend... Thank you!

All the best,
Brendan.

Thanks Martin.
As the comms is via UART anyway via the built-in UART to USB, it makes sense to use the UART.
If the UART is missing incoming data, then there is a UART with a circular buffer example

[Brendan]

Further to replacing the USB Serial component with UART, I'm delighted to confirm the project compiled successfully.

Having since received/programmed an ATMEGA2560 board (Arduino clone) using Microchip Studio, ICSP programmer and exported 'ELF' file, the board fired up and worked straight off the bat. The only minor exception being a timer interrupt not pulsing a heartbeat LED, though something that I can live without until I've investigated further for future projects.

So, thank you both again!
