Hi, I am doing a project using 8051 and GSM module,SIM900B. I am using a 8051 microcontroller to send AT commands to GSM module and store the data in an array and send the stored data as a text message to a mobile . I am able to see both gsm module and microcontroller unit working perfectly when connected to computer seperately through serial cable,but when I am connecting both the devices with t...

Just a quick question regarding 8051 assembly programming: I need to transfer a value from register R5 to R0, so I can use R5 for something else. I tried MOV R0, R5 but it fails. I know this is begginer's question, but I guess it wouldn't take to much time for someone experienced to answer this. Thanks Josip

You-all came through. However, I was overwhelmed yet, I still haven't found what I need. I am looking for an 8051 uc that has lots of flash and lots of ram and an internal rtc and some a/d and d/a. SPI and I2C would be very nice. I took a hiatus when the 89c668/9 series was in vogue and now, it doesn't SEEM like there has been a huge amount of new versions. Where am I going wrong? ...

Greetings everyone, I'm new to programming, and I'm having trouble running a c program in an 8051 emulator. I'm using emu51.exe (http://sourceforge.net/ projects/emu51/) with asm51.exe (http://www.metaice.com/ASM51/ ASM51.htm). When I use asm51 to convert the c program to a HEX file, I receive the following message: C:\UHCL\CPROGR~1\asm51> asm51.exe 8051 Cross-Assembler, Version

Looking for opinions on possibly moving from the 8051 family to the AVR's. Im an old timer and really prefer the Harvard a architecture, but i do realize that the '51 is getting pretty dated. It seems like the AVR is my logical step, but was wondering on what others out there my think, who have gone thru the change themselves. Tks all.
