 | | Interfacing PICs and Basic Stamps to Handy
|
|
Since (I think) it is fairly easy to interface the HC11's SPI interface to a PIC/Basic Stamp I & II this is probably easier than creating a custom RS-232 interface. Has anyone done anything like this? Sean R. Cunningham (29 years ago, 28-May-96, to lugnet.robotics.handyboard)

Lyle, Make sure you get the pcode-2.81 tar file in the interactive-c directory on cherupakha. -Fred (...) (29 years ago, 28-May-96, to lugnet.robotics.handyboard)

(...) I just noticed that the Polaroid Specs say that the transducer pulse current is 2 A. 100mA idle. Since it was mentioned previously that the HB's VR is rated for 1 Amp, how would this affect the sonar? Perhaps whatever is left of the 1A (...)

Greetings! I have just built my first Handy-Board.. Works Great!! I can't decide if I will enjoy writing software or building expansions more, I guess I'll just have to do lots of both before I decide. Two questions. My 'bot has it's own 12 volt (...)

(...) Yes, see the FAQ for a recently added section on the battery charging system. (...) Yes, this is a good idea if you are separately charging the HB's battery. As you correctly surmise, you don't want the two charging circuits contending with (...) (29 years ago, 1-Jun-96, to lugnet.robotics.handyboard)

| | Relationship between voltage and analog()
|

Hello! Would anybody please send me a mail letting me to know the relationship between the output of ananlog() function and the voltage ? For example, if my sensor works under the command "if (analog(0)>47) then ...." What would be the voltage ? Any (...) (29 years ago, 1-Jun-96, to lugnet.robotics.handyboard)

(...) The input voltage range is 0 to 5 v, and the output number range is 0 to 255. The relationship is linear, so 2.5v = 128 (for example) (...) to convert from the output # to the voltage, it would be 5v x (output # / 255) so 47 is about 0.92 (...)

Greetings! (...) Stupid Question.. Where is this faq? Web or FTP? I also couldn't find the file pcode_2.81.tar you mentioned last week. I will be porting IC 3.1, but wouldn't mind doing 2.81 while waiting for the 3.1 source. (...) Yes, The HB nicad (...) (29 years ago, 1-Jun-96, to lugnet.robotics.handyboard)
