While looking through the code 'pcode.asm' I came accross reference to various encoder routines that enable Y0 and get RSE code from the data bus. How can I call these within a C Programme ? I've not seen this feature documented anywhere (or maybe (...) (27 years ago, 15-Nov-97, to lugnet.robotics.handyboard)

I just got the set of Motorola HC11 guide books and reference manuals. I can highly recommend them - I am now able to understand the processor better, and how to take advantage of its many facilities. However when requesting them from the web site I (...)

The IR led I assume would be the transparent one and the detector would be the black one? There are 2 leads on the transmitter and 3 on the detector, how and where should I connect it to the HB? Any diagrams available? If this works, I have about 10 (...) (27 years ago, 14-Nov-97, to lugnet.robotics.handyboard)

The second argument is the mask which indicates which bits to make high. bit_clear in english is "for the byte at this address, (...) (27 years ago, 12-Nov-97, to lugnet.robotics.handyboard)

(...) Interesting sounding project Melissa. The trick is to distinguish the doorbell from other ambient sounds heard picked up by the microphone. One approach might be to use the LM567 PLL Frequency Detector. Its a relatively simple little 8 pin IC (...) (27 years ago, 12-Nov-97, to lugnet.robotics.handyboard)

I am a highschool intern trying to build a lego robot which models a housepet using the handy board. My task involves the robot sensing a "doorbell" and moving towards the sound. I will need to use microphones to accomplish this and I am wondering (...) (27 years ago, 12-Nov-97, to lugnet.robotics.handyboard)

Hi John, JJ> I am just writing to see if you still have the PCBs available. If Yeah, I do - the guy I originally emailed hasn't got back to me yet. Neither has anyone else actually! I'm just in the process of enquiring about ordering a Fingerboard (...) (27 years ago, 12-Nov-97, to lugnet.robotics.handyboard)
