#136686 - single crystal for two 89c52 |
I am interfacing two microcontrollers using serial communication..
I hav connected only one crystal to both.. I hav connected crystal to one microcontroller and 18th pin of one is connected to 19th pin of other... the first controller is working fine, but the second microcontroller is working very slowly.. i think there may be problem with crystal connections.. how can I connect same to get both controllers work fine?? |
