#71167 - RE: Detect crystal frequency of 89C52 Responding to: ???'s previous message |
We had a long debate on this whether to create to software versions or keep one version. We don't choice to create two version as it will create confusion in feild.
I liked the idea of using EEPROM to measure time. I have though it this way " It seems it is impossible to do it with out a reference so i detect crystal only once and store flag in unused area of EEPROM or RAM as it is battery backed . Use the flag for future reference. " Thanks for all your support. |
