did any body had tried to transfer data from one c51 <master> to another c51 <slave> by use of serial port
i am trying to work this thing but i fails some how. if any one can provide me some code for reference to this problem...
sir if you have any example of modbus implementation it will be more help full to understand it.
No. sample code can be of great help, but you must UNDERSTAND what you are doing. sample code, that often places arbitrary values in registers, will be of any help. you must read the respective data sheets.
Have you tried "modbus" as search expression on Google?
It has huge amounts of information about both the function of Modbus and how to implement it.
The code I have is proprietary, i.e. because of copyright, ownership etc can't be posted.
The hard part is to keep track of your transmissions, and turn off the transmitter immediately after the last bit of the transmission is done, to make sure that multiple nodes does not talk at the same time.
sir, i had gone through the google search, but i am not clearly understand it, if i got some example of, i might be clear it out, sir if you send me your code on urvil_suthar@yahoo.co.in
