 |
|
Hello,
Anyone know what i make wrong?
I try to sent serial a 32 byte array from one pcb, to a display
see what will be sent
for ciclo = 1 to 32
reset watchdog
print #2, esp(ciclo) ; " ciclo " ; ciclo
reset watchdog
next
result is ok!
value ciclo
-----------
65 1
80 2
1 3
2 4
3 5
4 6
5 7
and so on
'sent it to display
Printbin #1 , esp(1) , 32
'
'
'
'receive on display
waitms 10
Inputbin , Rx_dados(1) , 32
'see what has been received
for ciclo = 1 to 32
print #2 , "ciclo "; ciclo ; " " ; rx_dados(ciclo)
next
Result:
loop value
--------------
ciclo 1 0 'here is the problem, the first byte is allready a 0 and the byte sequence have than a offset of 1, why this?
ciclo 2 65
ciclo 3 80
ciclo 4 1
ciclo 5 2
ciclo 6 3
ciclo 7 4
and so on
Can anyone help
Thanks
Regards

1) You don't use code-tags, your intermixed code and message is a pain for the eye.
2) You don't show complete code, thus for example it's not understandable why a delay of 10ms is used, also it's impossible to check whether the UART's input buffer gets preloaded by some erroneous code.
3) You don't explain exactly what you want to do, it's guesswork that you have problems with a display and now you try to attach a controller instead to check what's going on. Or is the display connected with the receiving controller?
4) If you want answers, be better prepared and show more respect to potential helpsters. |

Hi MWS,
Like the help:
When you use Printbin ar(1) , the whole array will be printed assuming that CONFIG BASE=1
It is solved, make change on the display code
Thank you
Best regards

It is quite likely that nobody understands from your reply what the actual error was.
You had 56 views and no answer beside mine, which is IMHO due to your lousy presentation of the problem.
After you got it solved somehow - guesswork would be Config Base = 0, or code different to what was shown - you do still not respect the viewers of this forum.
A forum is no litter-box where you can unload your junk and leave it this way, a forum is something other readers may draw information and benefit from.
At least I am not able to draw any benefit from your posts and remember, I was somebody willing to help.
If you like to give something back to the forum, then explain what your actual error was and how you did solve it.
Of course you don't have to respond this way, the same as I don't have any obligation to even notice your posts in the future. |

Hello WWS,
Sorry, i explain
I have a main pcb that read on power up a file with a lot parameters and store it on external eeprom
This modul is a master and works serial with aprox 50 slaves pcb's (displays and other pcb's)
To look failures and other staff, as to discharge parameters to all connected displays slave on the network,
i design a console with TFT display, now i can programm this parameters in one time to all conected slaves displays
The problem was, that printbin sent entire array based on Base 1 and on the receiver side i use lookup table that begin
with base 0, so i solve it on the display side, ignoring the first received byte, that solve the problem.
Thank you for your time
Regards
