Hello aratti,

Yes i have the pulldown and the pullup resistors connect, not solve

with this i receive on the display the data on the atmega88 controller that works as slave

_start:

If Ischarwaiting() <> 0 Then 'test if char arrive
Inputbin Serialchar 'get it
If Serialchar <> 254 Then Goto _start 'the first value must be 254
Inputbin , T_destino , Crypt 'get the rest two values
Clear Serialin
End If


the works as master, and send this binary data

i try to send it as decimal as too hex
serout2 disp_pos,396,[dec master,dec destino,dec posicao]
and also
pause 1000
serout2 disp_pos,396,[hex2 master,hex2 destino,hex2 posicao]

unfortunatly without sucess

I have no more idea what can be wrong
