I am posting this for in case any body is interested as I know that I will be trying to make use of it. I apologise in advance to anybody who already knows how to do this, or does not intend to use such a range finder, but I imagine there are a lot (...)

It's unlikely you killed the MCU, there are 1k resistors in series with the RxD and TxD lines. Go to the assembly manual, and run through the series of tests that verify proper operation of the Interface/Charger Board. (URL) your message you said: (...)

| | External motor power
|

I want to use an external battery for motor power. I see the power expansion header apparantly for this purpose but it appears that I have to cut a trace to disconnect the HB battery from MOTORPWR. Is true? Is there anything else that I may have (...) (27 years ago, 17-Nov-97, to lugnet.robotics.handyboard)

|
|
A few months ago I found information on how to modify the Sharp IR Demodulator to produce an analogue voltage relating to the strength of IR received. The problem is that I have lost the information and can't remember where I saw it. Has anybody (...) (27 years ago, 17-Nov-97, to lugnet.robotics.handyboard)

Help! I accidently plugged a network rj11 cable between my HB and the serial interface board. It seems that I released the smoke genie from R 11. I have replaced the resistor and the MAX 232 but I'm not getting the board to sync. Is there anything (...) (27 years ago, 16-Nov-97, to lugnet.robotics.handyboard)

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)

bit_set in english is "for the byte at this adress, make these bits high". The first argument is the address (i.e. 0x0e). 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)
