Dan, I am not really an EE type, is there any ROM pro PROM requirements to get a HC11 for building or replacing in a handyboard? I thought the bootstrap logic...
Hi, I am just started in learning about this board. I have a class project in making a fire fighting robot. I use UVTRON sensors and it did great in detecting...
Jim, Every HC11 type has its own architecture, the A1 has 256bytes internal EEprom, some have more and some have less. I think the E1 is about as close to the...
Dan, Thanks, I think my question is really is there any eeprom programming that is unique to the HC11A1 MPU installed on the Handyboard vs one ordered from...
Jim, Ah I see what your asking now. No, the Handyboard does not need any custom EEprom or Prom burn in. What they are talking about on the Mot site is the...
Because the 68HC11a1 has the special boot mode, ie. when you press stop and turn on power, this brings the Processor into boot mode which means you can then...
Hi: So I'm trying to get my handyboard to talk to an RF reciever, and am getting nowhere.. I'm using the myserial.icb files from acroname, and that gets me a...
Hi everyone, Could you please provide me with example, how to mount shaft encoders in robots? ... Do you Yahoo!? The New Yahoo! Search - Faster. Easier. Bingo....
Hey guys, you've all been a lot of help last time. Thx. Got another question. Just how many SPI devices can I connect to the HB? The miniboard has two SPI...
Hey everyone, I am trying to have the handy board communicate with an RF transceiver. I found a way to decode the signal, but I thought it may be easier to...
Dear readers, What would happen if the motor I connect draws more current. Will the L293D blow out? If so, will there be any damage to other components esp....
I'm using a Handyboard to send serial messages to a GSM modem as part of a Uni project. From the contributed software on the HB website I found Richard...

Are you a 68hc11 user? Do you like the Botboard, or how 'bout the Handyboard? Have you used either of these and wished that the Botboard had more capabilities,...
Hehe. I don’t mind, but you should have put some sort of info-mercial alert :-). At least this thing could in fact be *made* to slice bread, if you decided...
James, You can allocate an array of 32 characters as a buffer as: char inbuff[32]; You will need to be sure you have set aside enough space for the longest ...
Hello, I am a beginner and I was wondering if anyone could explain how to solder the leads of a capacitors to the leads of a resistor. Do I just dab the...
My method would probably be to create little hooks on each of the leads, put them together, then solder. But I'm not an expert. I would also highly recommend...
If you just want to solder them together, just do like you said and dab the ends with the solder. but if they are going to be soldered in a board, the best...
Thanks! I practiced on a random board and I connected the two leads and then dabbed it with the solder and it looks like a mountain or a triangle, is that how...
Hi all I am running into problems where the handyboard's analog inputs are not reading a sensor output. I have 2 sensors 1 IR and 1 color. The IR works fine...
hi I have just finished making the board but when I try to download the firmware it all goes wrong. I'm using interactive C V4 to download the firmware but it...
does anyone know the memory addresses of the serial input buffer? Due to data loss when sending data to a radio receiver hooked up to my handyboard serial...
go to mouser.com and digikey.com, search for H22A1 or H22A2. These are called "infrared interrupt switches" or "interrupter modules". You cut a piece of paper...
yes, if the motor draws too much current you could destroy whatever you are hooking them up to. If you want to use motors which need high current, use an...
