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 Experience Have lot of embedded experience developing hardware and communication protocols Proposed Milestones $333 AUD - Project delivery. Final price will depend on final specifications Can we discuss?

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 Experience Please look at my profile Proposed Milestones $110 AUD - when start project $110 AUD - after the demo video I'll use 3 Arduino board for the demo but will delivery the software only

Hello, thank you for the opportunity to bid on your project! I have written several master/slave implementations that work over RS232. Relevant Skills and Experience Your project has special hardware requirements which would need to be ironed out before we could begin work. It could be very straightforward but more detail is needed. The actual protocol is easy. Proposed Milestones $50 AUD - Resolve hardware confusion - could be very easy depending on specifics. $200 AUD - Implement master/slave protocol that achieves stated objectives $83 AUD - Delivery of all source code and project notes
