Hello!. Sorry for my english. I have question: it is possible to connect atmega32(5V) with CYWM(3V):Vs atmega32 - 5VVs CYWM - 3,3VMISIO, MOSI, SS - atmega32, CYWM - 5V!!??Thank You.RegardsMarek
Hi,Good QuestionI think it shouldn't create any problem as long as voltage levels for logic high & low are within required specifications of digital families...For Receiving data from 3.3 module to avr doesnt create any problem as logic high for atmega=0.6*VCC= 3vBut Transmitting data to module does have voltage levels mismatch.so we should use resistor divider for MOSI pin to bring 5v to 3v conversion...We havent taken care that...Refer to this site for schematic.. Spectrum AnalyzerI referred to this blog...Lars Englund BlogRegardsMahavir
