Hello,
I made a program within the uVision3 IDE and used to be debugging with a MCB2130 as a target. Because the package with the stuff needed I used the simulator so that I could work ahead.
By the time I received the package I finished my program. It's an advanced Blinky program with several options of led-loops and several options to repeat them etc. To set-up the correct options and loop you have to use the UART1 window and your keyboard as input.
Now comes my problem.. because in the simulator everthing works like a charm however, if I want to debug the program using the Ulink2-USB-kit I can't get to output text on my UART1 screen within uVision3 IDE.
Is there a simple sollution for this or is plain impossible?
Thanks in advance,
Ruud van Heugten
" you have to use the UART1 window and your keyboard as input."
That's in the Simulator, because the simulator doesn't have a real UART1:
* The UART1 window simulates the output from the UART;
* The keyboard simulates the input to the UART.
When you use the uLink, the code actually runs in your target hardware - it is no longer just being simulated in your PC! Therefore, the UART1 output actually comes out of the real, physical UART of the microcontroller, and what you previously typed on the PC keyboard has to be sent as serial data to the real, physical UART of the microcontroller.
You can use a Terminal Emulator (eg, Hypoterminal) to do this...
Allright I See.. offcourse.. didn't think of that..
To use the physical UART of the microcontroller can I use the ULink2 box in combination with an Terminal Emulator or is it only possible when I connect an COM-cable to my PC?
"To use the physical UART of the microcontroller can I use the ULink2 box"
No.
Like I said, the UART data goes in & out on the physical pins of the chip as electrical signals - so you need to connect these signals to a suitable device (eg, a PC COM port and a terminal emulator).
The uLink just interfaces to the chip's on-baord debug logic.
OK I have got it to work. It prints the text to my screen nicely. Problem now is.. I can't send output too the MCB2130 eval. board. I think it's a simple setting mistake but tried a lot of things and non worked. So if you could help me out a little bit more that would be great.
Have you set the terminal program to use 3-wire intrface, or connected RTS/CTS on the PC side - yur terminal program is probably waiting for ok to send any data.
Before I got to test it when I was trying to debug I noticed whenever I executed printf() statements my JTAG connection was lost. Could that be the problem? Some registers that aren't right?
At this moment I ain't receiving error-messages in uVision3 IDE.
p6.6,50,*RXD2,"Debug, SerialPort, DSPortAdapter",Can configure as native I/O p6.7,49,*TXD2,"Debug, SerialPort, DSPortAdapter",Can configure as native I/O How can I change them to general I/O？Which register control them? Thank you.
