| Ich nutze: C-Control II Unit, CC2-Application-Board |
My german is too poor, so can I make it in english?
I want to use both hwcom and swcom on a CC2 controler with the development
board.
I directly connected TxD and RxD and ground for HWCOM without using the null
modem cable.
For swcom:
I connected P1H2 on digital RTS.
I connected P1H1 on digital CTS.
I connected RxD of the PC on SWCOM TxD.
I connected TxD of the PC on SWCOM RxD.
I connected pin 5 on PC (ground) to the ground of the CC2.
I used in both case shielded cable.
I am using OS v3.0 and the SP2 2.13.
I can use the COM2 (hwcom) to flash the memory of the CC2, and COM1 (SWCOM)
works. But when I plug both serial port (com1 and com2 to swcom and hwcom
respectively) and run the program, it hangs. I have to unplug SWCOM (com1) to
see the output coming to the terminal (hwcom).
What can I do to have both port working simultaneously?
What did I do wrong?
Here's the code:
thread main{
int k;
string s;
swcom.init();
hwcom.init();
hwcom.setspeed(hwcom.SPEED_57600);; // 8: 57600 BPS
swcom.setspeed(swcom.SPEED_9600); // 5: 9600 BPS
hwcom.clr();
swcom.clr();
for k=1...2000{
s= "HWCOM";
hwcom.send(s, str.length(s));
s= "SWCOM";
swcom.send(s, str.length(s)); }
}
Also, thank you very much for your tremendous work on the CC2.
