Question:
How do I use UART or serial port code on my STK200 board?
Answer:
The best way to see the UART code examples working is to use Hyper Terminal on PC, if your PC has a serial port. If not use a USB to serial converter. Hyper Terminal is included in most Windows OS, except Windows 7. It can be downloaded as an evaluation copy for Windows 7.
- Connect a serial cable to PC serial port
- Run Hyper Terminal (START > Programs > Accessories > Communications ) or Start > Run hypertrm (not a misspelling)
- Create New Connection, give it a name
- In Connect to Dialog box select Connect Using... COM1 (or whichever COM port you have connected to - it lists available serial ports). Ignore phone stuff
- When you click Ok, you get COM1 Properties dialog - set them to 19200, 8 data bits, no parity, 1 stop bit and flow control None
- Go to File menu > Properties, Settings Tab, Ascii setup button. Check Echo typed character locally so you can see what you are typing. Check it is connected on Call menu and type a character, which should then appear again from STK200, if code is running. Try pressing switch 7 on STK200 board and you should see "Hello World" in Hyper Terminal screen
