Hi guys, i am doing a beverage ordering system for my mini project, customer on each table will order beverage through keypad and the data will be send to a main station . In the customer pic microcontroler program , i plan to store data as table number, type or drinks they order, while in the receive part i plan to display out the data for a few seconds for the worker to look at.
The problem is , now my receiving part i am using a interrupt to get data and display in lcd, this only works well , when i have one customer, if a number of customer sends data i will have problem
Can someone suggest me a idea how to solve it, i am using bluettoh xbee to send data
