Devise a communication protocol/method to communicate to between devices, through RS232. There is one ‘master’ and up to two slaves, which communicate two ways. Slaves will have unique addresses. Code needs to be compatible with ATMEL microcontrollers as this is what will be used.

Communication is simple and will take the following form;

• Master to slave

o Turn output 1 to 8 high/low

• Slave to master

o Status of X input is high/low

The command sent may have some form of character identification to determine the type of command sent, before having input/output identification and then finally high/low status.

Example:

• OUTXY

o Where “OUT” is output command from master to slave

o X is output number

o Y is high/low status

• FUSXY

o Where ‘FUS” is input status from slave to master

o X is input number

o Y in high/low status

There is something wrong in the specifications. While protocol for communication ( reliable) can be done, connection architecture appears to be wrong. Need to discuss your overall objective Relevant Skills and Exper 更多

Your OUTXY in the example should include a flag for slave address (0 or 1). If using rs232, will need an additional status line beside tx/rx to avoid collision when 2 slaves send data to master Relevant Skills and Exp 更多
