use simple serial communication to send data to UART.

see tutorial for more help..

erm...i mean is the coding (assembly language) for 8051 microcontroller not coding for visual basic.

The asm coding is for the micro to send data to the pc(serial Tx) and the VB program is for the PC to receive the serial data from the micro(serial Rx).
Instead of coding in VB,for testing purposes,you can use the hyperterminal program.If everything goes well then you can create your custom application in VB.

from the UART tutorial, i found two note: 8051 programming to UART and software UART for 8051. Is that coding in both note are need for my circuit? Or either one note coding already enough? Have any similar example of ready write coding for reference? thanks

8051 UART programming is the one you need,not the software uart.
The software uart is for emulating a hardware uart in situations where the hardware uart is unavailable.

sensor.zip
following is the coding i modify from the DS1820 Based Temperature Controller (AT89C2051) at download section. can anyone help me check my coding is correct or not? thanks

have you compiled it and tested it on hardware yourself?

If not please do it only then we will be able to find out what the problem is and it will be easy to debug it. I hope you can understand.

i am on the way of purchasing the hardware component. however, i found that at my county hard to purchase intel 8051 microcontroller. if i replace the microcontroller with atmel 89c51, do i need modification on my project?

for compiling, i am using asem 5113. is asem 5113 good or got any other better compiler?
