I have been playing around with your libraries for programming an ATTiny85 at 8Mhz but find that it is failing to detect the 0x44 - Convert Temperature when sent. The 0xBE - Read Scratchpad works only from your sample master and not from my program with nearly identical code that works with DS18B20 temperature sensors.
My master program detects, converts DS18B20 temperature sensors without any problem.
Not having an oscilloscope I am at a loss as to where the problem may be. I am assuming a timing issue but am not sure where to look next.
Any ideas would be most welcome.
