Im sorry for starting two threads but i began the first one in the wrong place and i saw a comment from someone regarding posting in the correct place so i changed it to here, Next the suggestion that you provide me with the completed piece of code was not a serios one as i would have thought the tone of the following statement in the post would have suggested, getting a ready built piece of code is not what i am after at all as this would teach me nothing.
Now in the post that i started in the wrong place there is a picture, this picture shows that i do not wish to use more than one chip.
so i assumed that although related to your method using more than 1 chip that there would be a new set of complexities involved in using 1 chip so i started a new thread. Again if this was not the correct thing to do i am sorry.
i would now like to know where this question has been answered
so that i can read this information and maybe get some use out of the replies
quote:
If i was sending data to a device (nmea) what would be the maximum interval between transmissions before the nmea device detects an error and displays the error or is this not defined in the standard?
i do see similarities between the above question and the one below that has been posted, However it does not answer my question,
quote:
As there is no defined timing between the different talkers
all that aside please forgive me if i have upset anyone.
Now here is my code so far, and although not completed and there are no timeouts yet , being new to this i want to iron out mistakes before the code gets to complicated for me, running before i can walk as it were. I do not mind if i miss some sentances from a pin while i read another unless the recieving device minds the break in information for that particular device, im not sure how long a device can go without update from a particular talker before it objects, which i asked about it in the question above.
If you see anything you dont think is right or you know of a more efficient way of achieving the same thing could you please let me know thanks.
the code:-
' Routine to read imea sentance from a pin and send it
' then do the same from another pin and send it.
testbyte VAR BYTE ' Define byte variable
pinin1 VAR PORTC.1 ' Define serial pinin1 as PORTC.1
pinin2 VAR PORTC.2 ' Define serial pinin2 as PORTC.2
pinout VAR PORTC.7 ' Define serial pinout as PORTC.7
' For these examples, assume that the following string
' is being received continuously at 4800 baud on PORTC.7:
start1:
Serin2 pinin1,188,[testbyte] ' read portc.1
if testbyte = "$" then begin1
goto start1
begin1:
Serout2 pinout,188,[testbyte]
goto loop1
loop1:
Serin2 pinin1,188,[testbyte]
if testbyte = "$" then start2
Serout2 pinout,188,[testbyte]
goto loop1
start2:
Serin2 pinin2,188,[testbyte] ' read portc.2
if testbyte = "$" then begin2 '
goto start2
begin2:
Serout2 pinout,188,[testbyte]
goto loop2
loop2:
Serin2 pinin2,188,[testbyte]
if testbyte = "$"then start1
Serout2 pinout,188,[testbyte]
goto loop2
