Stable ADC readings

EDIT :

See logs for what reacts FIS with sent caracters ... Attachment 6112

LineK schematics , but we need a program to send values to see how reacts car radio LineK wire ...

code :

data(data line),clk(clock)
suma=0
dat=126
Shiftout data, clk, 5,[dat]
suma=suma ^ dat

Rem High data

dat=237
Shiftout dato, clk, 5,[dat]
suma=suma ^ dat

Rem Low data

dat=15
Shiftout dato, clk, 5,[dat]
suma=suma ^ dat

Rem High data
It is for DATA Line send (ENA/CLOCK/DATA)

For cont=0 To 15
tmp=msg[cont]
Rem dat=255 - tmp
dat= ~ tmp
suma=suma ^ dat
Shiftout data, clk, 5,[dat]
Rem Low data
Next cont

'Somme de controle (sum)

dat=suma + 1
Shiftout data, clk, 5,[dat]
Rem Low data
High ena
posy=255
GoSub display


FisDw:
Low ena
suma=0
dat=169
Shiftout data, clk, 5,[dat]
sum=sum ^ dat

know 255-longitude del msg

dat=241
Shiftout data, clk, 5,[dat]
sum=sum ^ dat

It is for example ,but it is a little part of sent values .

Thanks in advance to ameliorate or given answers .
