#101658 - you have created just about the worst co Responding to: ???'s previous message |
3) what size are the pullup resistors ?
3) 4.7k Ohm 5) how far are the uC and the max6956 apart ? 5) Maybe 16 inches via the jumper wires I'm using. 6) the MAX6956 I have plugged into a breadboard. you have created just about the worst conditions under which to run IIC. you have very large stray capacitances and high value resistors I doubt the bus ever get high in time. 4) does other things the uC do work? 4) ? I don't understand what you are asking here. Does your program e.g. blink a LED or some such thing that works before you go on, study this one http://www.semiconductors.philips.com/acrobat_d...h_2003.pdf Is basically an IIC "bible".
