Hello everybody,...
I have some problem understanding the RTS channel for the async mode..
I have the AT3 module on the development kit. when i connect it to a Rs232 and the Terminal on the PC and i send reset command and then assign channelk command, on the terminal i can see the answer (correct) of the ant module...
So i connect it to a PIC, Rx, Tx and RTS channel on a GPIO...
But with the same commands it doesn't work..
I mean ...
ram int reset1[] = {164,1,74,0,239};
ram int assChan[] = {164,3,66,5,64,0,160};
ram char data3[10];
ram int* ptr;
ram int* ptr2;
ram char* ptr3;
int i;
TRISCbits.TRISC5 = 1; //this is the line of the RTS
ptr=reset1;
ptr2=assChan;
ptr3 = data3;
OpenUSART( USART_TX_INT_OFF &
USART_RX_INT_OFF &
USART_ASYNCH_MODE &
USART_EIGHT_BIT &
USART_CONT_RX &
USART_BRGH_HIGH,
21);
while(1)
{
for(i=0;i<5;i++)
{
while(BusyUSART());
putcUSART(*ptr);
ptr = ptr + 1;
}
Delay10TCYx(50000);
while(LATCbits.LATC5 == 1);
while (BusyUSART());
for(i=0;i<7;i++)
{
while(BusyUSART());
//Delay10TCYx(50);
putcUSART(*ptr2);
ptr2 = ptr2 + 1;
}
Delay10TCYx(50000);
while(LATCbits.LATC5 == 1);
for(i=0;i<5;i++) // Only retrieve len characters
{
data = getcUSART(); // Get a character from the USART
// and save in the string
*ptr3 = data;
ptr3++; // Increment the string pointer
}
}
So, i put the TX, RX line connected also to the PC, so the same line go both to the ANT and the PC... In the screen of the PC i can see the string coming, so they also arrives at the ANT, but when i reach the point that i want to hear the answer of the ANT it seems that nothing happens, ....everything remains hearing...
someone has a problem like this?...
thanks for your help...
I.
