This is the Revision B version of the Activity9 RoboBrick. The status of this project is work in progress.
This document is also available as a PDF document.
The Activity9 RoboBrick is used to detect communication activity between two RoboBricks.
There is no programming per se for the Activity9 RoboBrick. Inside the Activity9 RoboBrick there are two counters -- one that counts bytes of traffic from the master to the slave and vice versa. The Activity RoboBrick takes the least significant four bits of each counter and displays them. Thus, when the LED's are flickering there is traffic going on. For short messages, the user can count individual bytes going between the modules. The top bank of four LED's is for master to slave traffic and the bottom bank of four LED's is for slave to master traffic.
The hardware consists of a circuit schematic and a printed circuit board.
The schematic for the Activity9 RoboBrick is shown below:
The parts list kept in a separate file -- activity9.ptl.
The printed circuit board files are listed below:
The Activity9 software is available as one of:
