Has anyone tried to use one of the TI tsl1301 or 1401 linear sensors with the HB. I ended up with a few but am having a tough time trying to figure out what the data sheets are trying to tell me. Not real clear (to me). Bruce A. Moore (26 years ago, 21-Apr-98, to lugnet.robotics.handyboard)

| | Re: Help!! Polaroid problem!!!

Are you using a pullup resistor on the ECHO pin? If not that is your problem. The ECHO output is an open collector driver which requires an 4.7 K pull-up resistor between the output and Vcc. The pull-up is necessary for connecting the module to a (...) (26 years ago, 21-Apr-98, to lugnet.robotics.handyboard)

hi from France, I already have a handy-board running with a 11A1 chip and I plan to adapt the circuit for a 11F1 chip, with the same memory map. Does someone have any experience about running IC with this chip? Will it work with the pcode_hb.s19 (...) (26 years ago, 21-Apr-98, to lugnet.robotics.handyboard)
