I have 4 extra handyboard circuit, and I would be able to build them and sell them for some thing around 200$can (including the charger/interface board) any...
Hello, I was recently given the challenge to create a boat that will traverse a banked canal without any trouble, and travel at a fairly fast speed. There is a...
sonar is your best bet for distance sensors - unfortunately, its almost impossible to differentiate between the sides of the canal and other boats. Working out...
I am redisigning a robot for the Mechatronics department at the University of Utah and I am hesitant to reinvent the wheel on the issue of tracking wheel...
I haven't done it but you need 3 encoders to be able to read speed/direction properly. If you just need speed and not direction then you can do it with just...
heh I thought that was a dropped space typo.. tis a shame when one comes to expect another's incompetence rather than examining one's own ;) so how many AU$ is...
the handyboard has encoder support added with the extension board, and already has libraries for encoders, including quadrature encoders. you may have to write...
I'm using the handyboard to do some high speed motor control. Does anyone know the A/D sampling frequeny? Is it the same as the 2MHz system clock? Thanks....
nowhere near. the manual states that it takes 34 E-clocks for each input's conversion, and that's not counting processing and p-code interpretation. you can...
Hey, I just finished updating my homepage with my Fire Fighting Machine-PYRO. It's controlled by a SUMO11 board,has 6 sensors for line tracking(due to...
Does the handyboard come setup to run the E-clock at 2MHz? I need at least 20kHz sampling frequency. I'm controlling the speed of a very fast (5000 RPM) motor...
yes, the E-clock is the clock used for the RAM - its the crystal frequency divided by 4, and the handyboard comes with an 8Mhz crystal, so E-clock(handyboard)...
... time ... If by velocity tracking, you mean a directional encoder, there is a direct replacement for the IC 4.x encoder files in the files section of this...

I am in canada and price is under canadian curency. I would basically charg the price of parts and a bit of my time. it does not include the batteries and...
I guess I could fix you a package that is not assembled, the PCB and the parts I will get from digi-key. buying the parts for all boards at the same time will ...
Hi, I am new to this group and want to know if I can use the hardware of the cricket system to do localization. In my application, I have a bunch of cameras...
If the crystal (XTAL) runs at 8MHz and the E-clock is 1/4 this amount (2MHz), then what is the instruction time of the handyboard? I've received different...
It's confusing because the "instruction times differ according to the instruction being executed.. The machine "CYCLE TIME" will be 500ns. You must then look...
I'm trying to get outputs from the handyboard without using the expansion board. On the handyboard website it says you can use the J6 interface and set it for...
You can use the four SPI pins SS, MISO,SCK and MOSI as outputs using the method you described, however these are the only four pins you can control in software...
Thanks for the help. I have one more question though. I haven't purchased the handyboard yet. I wanted to evaluate its ability for the project I have first....
The SPI pins, or J6 are located to the top right hand corner of the HC11; just below the LCD. If you look at page 58 of the Technical Reference (Available at...
assembly commands take between 1 and 7 instruction cycles - check the reference manual's assembly guide for more info. there are a couple of instructions (but...
