Beginner!!! Please help

Hello again !!!!

I have a question. If I have to set any GPIO pin of a particular IC without the bridge chip(in this case,without using the W command) how can I do it?

I have absolutely no idea. You'd have to talk to someone who knows that chip.

What I mean is, can I #define the pin?

Most likely not - but again, I'm not sure what you have access to and how.

Hello !!!

I am transmitting the following data via ASC1 port.

Code:

---

void ASC1_send()
{
ASC1_vSendData ('W');                        //write to internal reg command
ASC1_vSendData (2);                                //push pull o/p config
ASC1_vSendData (8);                                //set portconf1 to 0x08
ASC1_vSendData ('P');                        //stop
ASC1_vSendData ('O');      //write to GPIO
ASC1_vSendData (0);                                //set it to 0
ASC1_vSendData ('P');                        //stop               
ASC1_vSendData ('S');                        //start
ASC1_vSendData (160);                        //device address=A0=>160 in decimal
ASC1_vSendData (07);                        //data
ASC1_vSendData (11);
ASC1_vSendData (97);
ASC1_vSendData (80);
ASC1_vSendData (00);
ASC1_vSendData (40);
ASC1_vSendData (55);                        //data
ASC1_vSendData (250);                        //data
ASC1_vSendData ('S');
ASC1_vSendData (161);
ASC1_vSendData (07);
ASC1_vSendData ('P');
}
void ASC1_vSendData(uword uwData)
{
  ASC1_TBIC_IR = 0;        //  reset transmit buffer interrupt request                  set = 1;
  ASC1_TBUF    = uwData;  //  load transmit buffer register
        while (ASC1_TBIC_IR == 0);//wait till transmission finishes
} //  End of function ASC1_vSendData

---

I know that the data is being sent to the hardware since I can view it using a Scopemeter.
I want to introduce a stop condition after the last char ie ASC1_vSendData('P') is sent. How can I do it?

Hello!!!

I want to generate a simple counter which will give me a certain delay eg 500msec in between 2 bytes of data that i am sending. How can I generate the counter??

Thanks in advance for your help.

So use delay(500); that will give you at least 1/2 a second. Typically more, with Windows.

There is no visible counter to delay(), however.
