hi
may i knw for what purpose ur doing this bcz if u want to do it .u need to understand ur alarm device schematic after that select one basic microcontroller and one GSM module but if u tell me ur application means i can help u clearly.....than
hi aliyesami ,
i understood ur requirement
1) how can I convert this serial data to usb to hook up to my pc ? and would i need to write my own device driver?
Ans:so for ur application u need to select microcontroller which suport UART and internal USB driver there are lot of manufacturer so...
do one thing first start to study about that sensor,tx,rx,and microcontroller (hardwere,softwere)k then u ll get some knowledge then u tried to do your self (just imagine and do it k) then u ask others for help bcz i faced same problem...
one more thing when i connected external ADC input (load cell sensor) source the last digit getting fluctuating and i tried in 12 and 16 bit also .as of my thinking y it is getting is when the mc busy with some other tasks (digital switching) with analog switching (ADC) at that time it may occur...
ADC output unstable ..

Hello,
