Another great source for h-bridge design if (URL) It gives details on how to build a PIC based motor controller, but more importantly, it has a great h-bridge schematic. Be sure to check it out. ---...--- Brian Schimpf schimpfy2@aol.com (25 years ago, 12-Apr-99, to lugnet.robotics.handyboard)

Hi all I just finished rewriting the GP2D02 routines by Kent. Seems all to work just fine....except that I don't get readings below around 55. Even if I don't have anything in front of the sensor (dist. to wall more than 2m) I never get a reading of (...) (25 years ago, 12-Apr-99, to lugnet.robotics.handyboard)

Where can we get info in designing H-bridges from descreet components? Is it sufficient to use just four MOSFETs or just four solid state relays?

Actually, if you have been following this thread, there are several ideas that have come up, including the solid state relay (reliable, high current, but SPST, moderate cost ), transistor to up the current(reliable, mded current, low cost, but (...)

| | HB_IR.C: which ports?
|

Hi everybody, I'm experimenting with Kent Farnsworth's program for IR detection (files hb_ir.c and hb2_ir.icb). In Kent's program there is a function ir_counts(integer argument), where the argument can have the value 4, 5, 6 or 7. I've found that (...) (25 years ago, 11-Apr-99, to lugnet.robotics.handyboard)

Hi everybody, I have IC3.2 and want to use the smooth PWM functions. I've already adapted my lib_hb.c file. If I use the pcode_hb.s19 file adapted for smooth PWM (downloaded from Fred Martin's site), everything works ok, only I end up with IC2.8! (...)
