iVIEW-100 Series user’s Manual, 2006, v2.0 ----- 96
7.2 Download/debug program with COM1
The COM1 of iVIEW-100 has three major functions.
The first function is to download program from PC.
The second function is to link PC for program debug.
The last function is as a general-purpose COM port.
When the iVIEW-100 is powered-up, it initializes COM1 to the following
configuration:
Start-bit=1, data-bit=8, stop-bit=1, no parity
Baud rate = 115200
Then the iVIEW-100 will check the state of INIT*-pin. If the INIT*-pin is shorted to
GND, iVIEW-100 will send the version number of MiniOS7 to COM1 & enter
console mode for user’s download/debug program. If the INIIT*-pin is open,
iVIEW-100 will search AUTOEXEC.BAT, If AUTOEXEC.BAT is present, iVIEW-
100 will execute AUTOEXEC.BAT. If no AUTOEXEC.BAT, iVIEW-100 will enter
console mode for user’s download/debug program.
After the power-on stage, the iVIEW-100 will use the COM1 as its standard
input/output. The standard output of iVIEW-100 will be shown on PC’s monitor. If
you press any key, this key will be echoed to iVIEW-100 as standard input.
Therefore the keyboard & monitor of PC can be used as standard input & output
of iVIEW-100 as follows:
Use MiniOS7 Utility or 7188xw.exe as a bridge between iVIEW-
100 & PC.
Run MiniOS7 Utility or 7188xw.exe in PC to setup this bridge.
Keyboard of PC
standard input of iVIEW-100.
Monitor of PC
standard output of iVIEW-100.
In this way, the iVIEW-100 can read some data from keyboard & show some
information in monitor. So the program debug will become more easy & effective.
Note: MiniOS7 Utility & 7188xw.exe are given in the companion CD.
Please refer to Chapter 3.3 ~ 3.5 for download program & 2.6.1 for wire
connection.
