Hardware Description Table 7

Thomas Br�unl, May 2015

Each EyeBot controller contains a Hardware Description Table (HDT) as a file stored in location:
/home/pi/hdt.txt

The HDT files contains important entries, which allow changing robot characteristics without having to change the robot's program.

Important HDT entries are:


Supported infrared remote is Chunghop L960E (code 786):
On remote press SET+TV buttons for 3 sec. (light on), press 7 8 6, then SET.
Example HDT file:
