#139920 - what\'s the problem, exactly? Responding to: ???'s previous message |

I had put delays between SDA and SCL changes in previous versions. I deleted them in order to check signals on the scope. I don't quite understand the need to remove delays to see the signals on scope... Philippe Latu said:
My guess is : I wouldn't be able to read data and to receive ack from slave devices if I didn't respect timings between SDA and SCL. Well, yes... but, isn't lack of ACK your problem? Can you describe us what do you see on the scope? Or, better, if it is a digital scope with some way to get the data onto PC, show us? JW |
