Hi, I have 4 of these GP2D12 sensor. The analog reading on the HB ranges from about 0 unblocked to about 130 at ~4". I was under the impression that it should...
Your sensors are working as expected. The output of the GP2D12 is not linear. I usually expect the handyboard to show a maximum reading of about 140 at 10cm....
Dear all 1-im asking about the availability of XIRQ and IRQ pins on the handyboard if its used or not, if not i'd like to utilize them in my project. what are...

Dear all am inquiring about the availability of the cross assembler to use the control structure statements ( IF, ELSE, WHILE , DO , REPEAT) in the handy...
On Mon, 11 Dec 2006 08:11:28 +1000, al.radaideh <al.radaideh@...> ... I use the gnu-m68hc11 toolchain ( http://m68hc11.serveftp.org/ ) with great success....
Amer, I am not sure what assembler is going to provide IF, ELSE, WHILE, DO code syntax. These statements are typically higher level languages such as C, Perl,...
I have been running and experimenting with some subsumptive type code that works quite well except for one thing - when certain states are true, my servos...
and what behaviors do those states imply? There is a hardware correction of 'servo jitter" that can be caused when high current devices like motors are active....
YES!! It happens when the motors (two fairly large ones) switch from a lower powered turn to full power straight ahead. Sometimes the states fluctuate rapidly...
Hi. I just wanted to say that it is not Interactive-C 5.x software causing the PC freezing. But rather my old PC (7-yrs. old at least). The problem was that...
Hi to all, Recently I bought a bluetooth module from sparkfun.com (bluesmirf). I connected it last weekend and it works ok to send and receive characters from...
I haven't looked at the drivers involved, but I suspect the IC program would be happiest with a "serial port emulator" kind of driver for the bluetooth. that...
Jim, Thanks for your answer, I think the "serial port emulator" is part of the driver of the bluetooth in my case. As soon as the bluetooth is connected to the...
Jose, Sorry to be unclear, What I mean is the "Handy Board Battery Charger & Serial Interface" device. This board provides the interface from the level shifted...
I'm going through a bunch of old stuff and came across some circuit board layouts that I had designed that add more digital outputs and analogue inputs to the...
I would be interested in them. Thanks- Carrie ... board layouts that I had ... handyboard. ... analogue inputs (8 and 16). ... Fred to post them on the...
Hi- I need to use five Sharp GP2D120 Sensors. I have read about cutting the trace to the pullup resistor and that this will not work for the inputs 3 and 6. I...
... From what I can see on the circuit diagram and board layout, inputs 0-6 are identical. Why would cutting the trace not work on 3 and 6? Inputs 0 and 1 are...
If you don't have the expansion board installed, you can read analog port 0 as analog(16) and analog port1 and analog(20). The expansion board multiplexes...
Thanks for the replies- As for ports 3 and 6 not working, I did try to cut the trace and it did not work. I'm not sure why either because the schematic does...
Jim, I understand now ! The bluetooth im using on the handyboard is the BlueSMIRF, it works directly on TTL levels, so I attached it to the RJ11 on the ...
Is working ! Yeah, it was the driver on the PC, seems that the Bluesoleil package is not good enough for using IC. I have left the Windows default Bluetooth...
To use the GP2d12 sensors you need to remove the pullup resisters. That is a given. I think I may have given the wrong ranges for the multiplexed sensors. The...
OK I've uploaded the schematics and documentation in the Files/Schematics section. There are plans for an 8 and 14 port expansion. They each require a couple...
I'm offering these bits to the list before I try it with eBay... HandyBoard v1.21 with expansion board, serial interface/battery charger, no power supply. $150...
Actually -- you can use a 2.2K pull DOWN on the sensor's output, and then it works fine with the Handy Board's 47K pullups! I forget who first told me this,...
Unplug it from everything and then see if it will go into bootstrap mode (hold down Stop button, power on, both SER and PWR LEDs should flash and stay off)....
