Flowcode Support Board

It works for me with the RedBoad/Arduino Uno.
I have some AtMEGA328P devices lying around at home.
I will see if I can replicate the issue with your settings when I get a chance.

I have just tried with a ATMEGA328P dip, 16MHz xtal and 2x 22PF caps.
All working as expected using Uart_exp v2.fcfx, posted earlier.
What I did to make sure the hardware was set up correctly, was to change the delays of the 1sec flasher to 10ms for a loop count of 100.
I then checked the delay was exactly 10ms and it was.
As the interrupt is working for me, I still would suggest you have an issue with your hardware.
I can't explain how the RX worked when not using an interrupt.

thanks! I think I found what was the problem. I was using software uart, which caused the interrupt to not work

Martin, thank you, could you tell me how I can send text to uart through the flowcode console?
I can not find it

That will be the case.
I did use Channel 1 UART for the demo I posted.
At least you have it working now.

I will need more information.
Normally the console is for simulation.
However, a tab can be created within the console, then any text entered can be transferred to a string variable for transmitting via UART.
Is that what you want to do?

thanks Martin
