#147965 - ±3% of the desired rate, Responding to: ???'s previous message |

Salaam Mehdi,
If memory serves, the values must result in a baud rate within ±3% of the desired rate. Salaaaaam Joseph, Yes it is totally right. you'll need to calculate the appropriate initialization values for a given clock frequency, iterating clock frequencies until you find one that lets you achieve both baud rates within the 3% tolerance. It seems it is the best solution. It is a positive for you if i had access to scoring! |
