Hi everyone,
I Need your help. I started to work with PSoC 5LP and I want to have a terminal set up with UART.
If I press T hh:mm = sets the current time for the device and if I write T? = prints the current device time.
How i get the Output, i have a Char for the Input of the terminal?
Char= UART_GetChar();
but not a Char Array... I don't know how to change it.
Thanks a lot.
Best
Marcel

Dear Marcel-san,
Could you take a look at some of my sample programs,
if they can be any help?

Hi Marcel,
There is no direct API to read the string in PSoC 5.
To read the character array you can use a While loop with UART_GetChar(); API inside and continuously read it until you find a valid character.
You can use a separate character array in the firmware to store the characters those have been read.
You can termiate the polling of UART_GetChar(); process until you read an "enter" from the terminal.
In case if you dont want to waste time with polling, you can use an interrupt which triggers on receiving a byte in the RX buffer. In the ISR you can read the characters entered and decide them if they are valid/not/string terminated(enter) and take necessary action.
Hope this helps !
Thanks
Ganesh

Hi GaneshD_41,
first I want to thank you for an answer.
Since I still don't know how to do this, I wanted to ask if you had a sample program in such a form where I could take a closer look at it?
That would certainly help me with my problem.
Thank you very much for helping me!
Best
Marcel
