UART studio

Hello Ferz,

Or include "inc/hw_types.h" in the start of the list of includes.

Hello John,

I wrote that down already, but still it's error.

Hi Amit,

i include that too already, still I keep getting the error.

Hello Ferz

Your CCS project would be useful for inspection.

Amit

Hello Amit,

so this is the error that I found:

Hello Ferry,

Not just the main.c but the CCS project (zip it and attach it to the post)

Regards
Amit

Hello Amit,

Here the zip file.

Thanks,
Ferry

Hello Amit,

Thanks for your help and it works out for the previous code. Now I have encounter new problem. There is no error in my code and when I ran putty and run the code the value is not shown up at putty. I upload the file in case that you need it.

Thanks,

Ferry 2480.UART.zip

There is no error in my code and when I ran putty and run the code the value is not shown up at putty.

That's not much of an error description. The way from the UART transmit register to the PC running putty is long.

Did you verify that there is a RS232 signal on the transmission line ?

Are the settings correct (baudrate/parity/start-stop bits) ?

Is the hardware correct ? A 3.3V GPIO output will not work.

And BTW:

There is no error in my code...

That only means there no syntax errors that make your compiler barf. The code can still fail catastrophically on the first instructions when running on the actual hardware.

Hello Ferz,

Where is InitConsole called in the program?

Regards
Amit
