------------------------------- Hi Thank you all for the support. I have a RTC chip on board HT1380. I tried using it as a reference . I could do it but this implementation is having a major problem. The RTC chip needs a Oscillator enable command before use (i.e. it needs to be set ) and it requires 3 sec to stabilise the oscillator. This is not feasible as far as current application is concerned Why ? Is a three second calibration pause not acceptable ? The actual measurement isn't going to tak long once you are warmedup, and the exsiting app has to wait three seconds anyway. Steve |
