in the picture I had just finish trying all the B ports., It was in RB6, which was the last of the port I tried
the sending IS on RB2
and Receiving is on RB3
go back to the web site i posted a new picture

Then put up a fresh picture and change your receiver to portb.2Originally Posted by lerameur

Ok so now both receiver and transmitter are on portb.2
the picture is up
would the problem be in the software, is the pic16f88 special and need extra attention ?

It does...but I think I'm onto something....
On the receiver PIC, it shows:
Waiting...127,22
The 127 is the number of times it's tried to receive data but timed out, the 22 is the number of times it's actually received 4 bytes of data and dropped thru to the display section.
Post your receiver code as it stands again.
Something is amiss. If the serial port wasn't receiving anything (i.e. the serin statement always timed out and went back to loop, the 22 should remain a 0).
|
for the receiving code, as soon as I open the power supply I get a different number
trial1: Waiting... 111,22
trial2: Waiting... 111,21
trial3: Waiting... 127,22
trial4: Waiting... 107,21
.....
when I leave the power off for a while, it seems to come back to Waiting... 111,22 when the power is turned on
once the number is there , it stays, it do not move, NO increment.

Try those code chunks. I get the feeling that the lcd at the receiver end might have been overwriting itself, thereby blanking out the data or something. I also added a couple of pauses in there so you could see what was going on. Also, you didn't set the receiver port to an input (I know serin says it does this for you, but I never trust stuff like that).

I tried setting Trisb.2 before and it did ot hnage anythimg so I put it rightback.
Ok now , the sending side, there is an incrementation, and for the first time try2 is incrementing, and it does so by 4.
On the receiver side, first line; empty, second line: 'Waiting... 000,000'
I also added these twoline:
DEFINE LCD_COMMANDUS 2500
DEFINE LCD_DATAUS 250
but no luck either

I'm off to bed , be back tomorrow morning

It's not incrementing at all on the receiving side? Try1 should be going up about once a second.
Add:
DEFINE CHAR_PACING 16667
to the transmit program's defines at the beginning. Maybe the receiver is missing characters 'cause they're coming too fast with the software based serin command. If that fixes it, it'll probably work with a value much less than 16667, but it's a start.

NO incrementation on the receiver. The same with all zeros all the time
what about using the serin2 command ??
with the new define, I can see glitches of 'Sending...' on the second line of the sending side. But most often it is on like before, 'Getting...'

absolutely no changes

On the receiver side...absolutely no changes
Change the word 'Waiting..' to
'Wait 4 it'
and see what happens
|
O my I changed to this
serin portB.2 , t2400 , [ temp.highbyte , temp.lowbyte , tempf.highbyte , tempf.lowbyte ]
now the temp is showing up on first line, BUT is it showing zeros,
incrementation on try, try2 fixed at 0
check the web page also, for output on lcd
also:
On the receiver side...
Change the word 'Waiting..' to
'Wait 4 it'
and see what happens ----------- Only the display changed

receiver side change - That's what I was wondering. I had a case a couple days ago where I thought it was programming, but the PGD wire had come loose from my board, so it wasn't actually programming, even though it didn't report any errors (and I had my verify turned off!).
Changing to t2400 is going to do exactly what you saw. But it doesn't fix anything. Leave it at n2400, or try changing both sides to t2400.
And try putting a small resistor inline with the big yellow wire, about 100 ohms or so. Without it, it's almost like a direct short from power to ground from one PIC to another. I should've caught this earlier.

I will leave is at n2400 then
also, are you saying my pgd wire is messed up ??
I am not sure what it is ? it is programming the sending side.., I am not sure what you meant
The 100 ohm resistor did not do anything .
Last edited by lerameur; - 24th December 2006 at 06:53.

Yes, try changing both sides to t2400 instead of n2400.
You must be pulling the chips out and programming them. Changing the 'Waiting...' was just a quick way to make sure the PIC was actually being reprogrammed.
I didn't expect the 100 ohm resistor to change anything, it's just a good idea from a 'safety' standpoint, saves PICs from blowing themselves up.
And this is going to sound a bit wierd, but I'm wondering if SERIN and SEROUT don't like to deal with temp.highbyte and would rather deal with a byte value instead. Give me a couple of minutes to rewrite the programs and I'll post them in a couple of minutes.

ok too much current, I get it
no changes with t2400 on both chips
Ok I changed the speed to 9600.
I get the temperature showing on the receiving ship, but its showing zeros.
also the increment try do not increment , But when i disconnect the wire, it increments every 0.5 sec

If that works, then great. I don't know why it works. The PBP manual says the other way should work, but I seem to remember running into this problem before and had to do the same thing, I can't remember what I was doing though.

still no changes from previous. I just check the hardware, and seems to be ok, Cystal is oscillating at 20Mhz on both sides.
|
Could ya post another picture?
|
actually I did, th e pic is back , i will do another one with the last circuit
I just tried sending a constant over, and displaying it on the receiving end and it still gives me zero, maybe breaking the program into even more basic ?
new PIC online
with this last program, both counters are working on both chips.

Did you make the changes in post #61?
I saw the new picture. Let me think about this for a couple of minutes...
Is the sending pic on the left or the right? Could you mark them with something...piece of masking tape on the transmitting pic or something?

o, I wil wait a bit,
the receing LCD shows only on the second line, with zerosss.

Are you splitting that program up between the 2 PICs or programming the whole thing into one PIC?
|
like on the picture, its 2 pics
i tried this thing but it do not work
loop:
lcdout $fe , $c0 , "Waiting.." , DEC3 try1 , "," , DEC3 try2
try1 = try1 + 1 : temp = 0 : tempf = 0
serin portB.2 , t2400 , [ temp1 , temp2 , temp3 , temp4 ]
if temp1 > temp2 then
Portb.4 =1 ------------putting a led here, maybe lcdout is confusing with serin
pause 500
portb.4=0
else
Portb.3 =1 -----------putting a led here
pause 500
portb.3=0
endif
goto loop
End

Ok I am really going now to sleep, see ya later

I meant are you putting the transmit code into the transmit PIC and the receive code into the receive PIC, not the whole thing into both PICs...

Ok, just checking because in that one picture it looked like both PICs had the same writing on them.I meant are you putting the transmit code into the transmit PIC and the receive code into the receive PIC, not the whole thing into both PICs...

And post a fresh picture if you can

ok , I'm back, still no changes,
picture up
The two leds there are from a previous program which instead of using lcdout, I was trying to make led blink.
but the picture was takien while your last program was working

i tried this program for the reciver. The led blinks, If I added the serin , led would sit on high. There is definately a problem with serin command, It does not work with lcdout or simple led blinking

Portb.4 =1 : pause 500 : portb.4=0
Portb.3 =1 : pause 500 : portb.3=0
goto loop
End
I also wanted to see if the chip was able to see the data coming in, so i tried this loop, and nothing is happening to the led:
loop:
serin portB.2 , t2400 , [ temp1 , temp2 , temp3 , temp4 ]
if temp1 > 0 then
Portb.4 =1 : pause 500 : portb.4=0
Portb.3 =1 : pause 500 : portb.3=0
endif
goto loop
End

Ok now I used your pogram and changed the serin line :
serin portB.2 , t2400 , temp1 -----works
It takes in the value,IT is NOW working. BUT For some odd reason it do not take multiple input..
serin portB.2 , t2400 , [ temp1 , temp2 , temp3 , temp4 ] ------------- do not work
|
methinks
Hi leramuer.
I think you need to store and retrieve those values in an array. I am not experienced enough to have confidence with this statement, but methinks it is so.
Anyone, ring in here with an opinion!
JS
edit:
try this
Temp var byte[4]
Temp[0] = n ' your first temp value
Temp[1] = n1 ' your second value
Temp[2] = n2 ' your third value
Temp[3] = n3 ' your fourth value
serout portB.2 , t2400,[# temp[0],# temp[1], # Temp[2], # Temp[3]]
it displays on my backpack display.
JS

Merry Christmas to all
I just tried that , the information is not sending. Maybe I got the code wrong, but it till skipping over the lcdout
