RS485 with 89c51

Le Xuan Huy

Hi everybody,

I want to receive data from a Loadcell Indicator throughout RS485. The LoadCell Indicator only send data to Micro chip. I also want my Micro chip communicate with the computer in both ways (transfer and receive) by RS232.

Can I do like that?

This is the first time I code for micro chip. I already try to use RS232, but with RS485 I do not have enough material to do. Please help me with any idea, useful links, papers or example codes.

I'm using T89C51AC2 micro chip and C in coding.

Thank you so much,
Huy
