(...) 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)

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)

(...) The FAQ is linked from the main HB web page under the title "the Handy Board FAQ", or directly at: (URL) pcode source is at ftp://cher.media.mit...dist.tar.Z and also (URL) should fix that last link, because you'd never find it unless you knew (...)

Fred, I have FTP'ed pcode-2.81.dist.tar.Z from cher (thanks for getting it back!) within it were the files foo.s19, pcode_rw.s19, lobo.asm, pcode.asm, and some makefiles.. Cool, but the files required for compiling IC 2.81 that I can't find are (...) (29 years ago, 1-Jun-96, to lugnet.robotics.handyboard)

Well, I didn't get far without running into a bug. In the interface/charger serial circuit, I get 17 volts at pin 2 and I get 0 volts on pin 6. The MAX232 chip is oriented to the right, and all the capacitors have their negative stripes on the left (...) (29 years ago, 2-Jun-96, to lugnet.robotics.handyboard)
