Hello!
Flowcode show wrong pins, but the HW uses the correct ones.

Sending 0 (zero) via RS232, the information not shown in the console.

Hi Bachman
Ive attached an fcdx for that chip, rename the one in your fcd folder and paste the attached one in, i cant test it as i don't have that chip on hand.
Can you then post back here if it's ok
Regards
Dazz
PLEASE FIND NEW ATTACHMENT FURTHER DOWN

Thank you!
The properties window is ok, only the chip name is too long. The console problem must be in the Flowcode, i think.

When you use SendChar you need to look on the
ASCII Table for the char being sent e.g 1 then look at the Dec number and send that value.
In the case of 1 you need to
If you want to send 0 then you use
:
An easier way to send a number is to send it as a string e.g SendString "0"
If you want to send a variable value e.g if VariableValue = 128
Then you could create a string then convert variable to a string then send the string:

Yes, it's a solution for the bug. If i convert the numbers into ASCII, i need extra steps on the RX side to convert it back to numbers. Sending zero via UART works fine in the HW, the bug "visible" only in the simulation.

HI Bachman
Sorry about the name i used it for checking and forgot to remove the extra numbers (doh).
I have corrected and reattached to this post

You don't need the extra steps to just send a 0.
Either sendChar(48)
or
SendString"0"
If you use SendChar(0) then that's a null character, not a 0.
So its just the termination of the string
The extra steps are only If sending a byte variable.

This is why i send 0, not "0".
