#137504 - Well you are right Sir Erik Responding to: ???'s previous message |
Well sir you are right , but i think that there are many ways, like
1. He can poll the the Clock Bit, and if its low then it could read the data on Data, 2. Or he can simply connect that Clock pin to INT0 pin of MCu and on every interrupt the MCu will get the data from the Data and save it in any Register, by using Rotating it to left or right, well i think that both methods will work for Mostafa, but i will prefer 2nd cuz its not waiting, :-) the MCu will be awaken when the INT0 is low, i think that you might have gotten the idea, well in other hand i would recomend Mostafa to use one MCU instead of 2 cuz it will be effective, such as cost and area, DareDevil |

| Why two MCUs ? | 01/01/70 00:00 | |
| This method "must be waiting" is, indeed 'daring' | 01/01/70 00:00 | |
| Well you are right Sir Erik | 01/01/70 00:00 | |
| polling will only work in the rarest of cases | 01/01/70 00:00 | |
I don't get what you want from all of this | 01/01/70 00:00 |
