Hi, I would like to develop this project as I have background knowledge of different serial communication protocols, for instance CAN, I2C,UART. In addition to it, have experiance development of system that is composed of hardware and software. In first step, I will design hardware architecture with required sub modules; in context of this project, 1. revciver/tranciver circuit design, 2. power supply for system, 3. human machine interface(HMI) and 4. firmware developement. Serial communication works based on frame; those are composed of specific number of bits. I have MDB manual to go though all the different type commands either control or data. In my job, I also did same type of work, where one master controling, number of slave boards using CAN communication. Further, it can be improve by designing the controller circuit, with low cost microcontroller(ST, Microchip etc) with custom build programmer and debugger. In the end, if you have any queries, feel free to contact me. Thank you!

Hi Could you provide a specification of this vending machine and also the list of commands that could be used by model. Or at least you could provide correct model no. of this vending machine so that I could contact to the manufacturer and get documentation from them. I have previous experience with 4.2 and 4.3 version s of MDB protocols. I am fully available for this project by now. Bid amount and deadlines are estimated for existing information. Please discuss details over chat. Maximum response time is 12 hours, although mostly I respond in minutes. Thanks for your attention Archil
