We are developing a machine which has a 7Inch touch screen (HMI). This unit has inbuilt WiFi and RS485 module.
Our machine has stepper motors which will communicate with HMI through RS485. I have attached the sample code from the HMI company for RS485 communication . What we need is an android firmware to control the machine.
Our machine has 7 Stepper (RS485) + 3 Servo (RS485) + 1 Analog + 3 Digital sensors
Expecting Completion Time: 1 Week
Attached: RS485 demo]
Android Firmware will have 5 main sections (Details will be given later).
this will be an interesting project to work on as i can assure you success on this project after going through the details and i have done several project with similar skills
