#168986 - adhere to the datasheet of the one you're using Responding to: ???'s previous message |
If you've decided on one chip, study the datasheet for that one, and forget about the others.
Nobody here is going to do your research for you. YOU must study the datasheet and draw your own conclusions from it. The fact that other manufacturers' datasheets don't refer to reset in the same context may not matter at all, and certainly doesn't in the context of the part you're using, aside from exactly what is specified in the datasheet. See if you can get that one to work. If it does, then you've succeeded. If it doesn't, well, you've probably mistimed or otherwise mis-coded. These specifications are generally not approximations. If it says "N Cycles" it doesn't mean N +/- 3 or some such. if it says 120 ns, or 150 ms, it's not joking about that either. Normally there's a minimum or maximum on timing. If you exceed the minimum and don't exceed the maximum, it will probably do what the datasheet says it will. Be sure you know what sort of timing your particular MCU/Oscillator combination produces in terms of the cycle length on the I2C. If you pay close attention to timing and protocol sequence, you should have no trouble. RE |
