[En-Nut-Discussion] RE: CHARON II I2C slave adress 0x20 :-(

[Joel Dotreppe]

Conrad,

Thank you for the answer,
but I already tested with several address:  40H.....!  8 bits, however' 
TWIF.C' accept 7 bits, is 20H. (sla<< 1 in ' TWIF.C ')
the chip number is well the TDA8444.
 When I test the circuit via the parallel port yew functions correctly.
