Haven’t update for a long time, due to I keep on sick. Right now I am facing the hardest problem – need to build up a better communication protocol between bricks and receiver. Previously, I just do it like this:
brick->brick->receiver
That means last brick will keep on send the data to the next brick, then it send back to the receiver. This scheme is not work since I forgot that will have delay for the code processing. As a result, it will make the data lost. So for a better scheme, I need to add a header into each data segment, and send back a data as acknowledgement to let the brick know that it got the write data.Also, the PCB is now on hold, maybe I will have some changes on it. Since it may need a oscillator for faster speed data communication.
After talk to my advisor last week, maybe I will change the idea if the time is limit. Hope the problem will be solve.
