#93758 - works on simulator Responding to: ???'s previous message |
Hello Srendhran,
What MCU you are using? what port you use to drive LCD? Some port pins of 8052 are Open drain (Normally P0, please correct me if I'm wrong) therefore, you need pull-up resistors. Read datasheet for more information such as Sink-Source current capablity of the MCU. From my personal experience, I always use these pins for RS,RW,and EN function with pull-up resistors on open drain port, and bi-directional pins for LCD data. Regards, T.L |
