hello friends... I am currently working on a project in my college in which I need to interface a number of devices with 8051 microcontroller like sensors, lcd, buzzer, gsm module, keypad etc. i couldn't find any good source on net about interfacing other than datasheets of these devices(which i found difficult to interpret:roll:) it would (...)
Hello friend, Can you send me your interfacing circuit diagram. I use P89v51Rd2 means 5V microcontroller and my GSM module (SIM900) is working at 4.2V, so how can i connect my Micro RX, TX which is at 5V to SIM900 RX, TX which is 4.2V support. Please help me to design my circuit. Thanks in advance. Regards, Ghanshyam

Hi, interfacing LCDs is in general quite easy. However if you are looking at character LCDs they all use basically the same (or compatable controller) a Hitatchi HD4470 or something like that. Anyway I might have some LCD code for the 8051 that I can dig uo if you need it. Cheers Slayer
