Why not connect the eval board directly with the Arduino thus leaving the PC out of the loop?
This is the step that i tried at the beginning. At the first sight i receive the project (Eval board adxl345 + arduino Uno) i am just planning to connect both without pc. But regarding to my previous post:
Mr.johnwasser suggested that my eval board is not suitable to connect direct to arduino since the pin mapping in the eval board already used up for another purpose. The only 1 possible way is using USB direct connect to arduino uno. But i faced another problem that arduino cant even been activated (maybe not recognize the eval board) when i connect directly Uno to eval board. For example, a simple code Serial.write("7").
Suppose the Tx led on Uno will be light up if data sent. But when i connect it to eval board. It is no light up at all. The data cant sent.
So i try another way, save the data to a text file and then transfer it to arduino. PC as intermediate medium. I really hope that i could find someone to help me out to hear my problem....
Sorry for my english if anywhere make you trouble to read this. Thanks
