Deleted library that was unnecessary
Added a new push button controller circuit. Uses new IC instead of solid state machine because there was no room for solid state machine circuit. Preformed changes that Abe recommended. Routed new circuits. Board should be ready to send back out to kwoo.
Added new switching power supply for 5V and 3.3V supplies. Routed board to include these, and switch.
Added packages to kwoo for diode, dd2pak for switching regulator and switch. Working on schematic for the new power system using switching regulator.
Added code for forklift AVR
twi.c and twi.h were taken from Arduino's library. forklift.c currentlyimplements i2c slave communication, but no motor control or sensor inputyet.
Changed library to conform with voltage regulator package. Redid routing to conform to new package. Add heat dissipation area. Still need to check that this is correct. Also fixed cap values for voltage regulators.
Merge branch 'master' of roboticsclub.org:/home/svn/scouthw
Added simple power circuit to the scoutfly reduced board. Using 2 new LDOs to regulate down to 5V and 3.3V Also removed the charging circuit, gas gauge, push button controller. Removed charge led.
Added forklift subdirectory to scouthw. Contains the schematic and board files for the forklift accessory along with a library containing the motor driver.
Added a new library with a voltage regulator part. I forgot to add the Name and Value so i will do that. I also added the start of work on the reduced feature set scoutfly.
Did some wire routing and part moving.
Mostly finished routing the regulator circuit
Made a little progress on the gas gauge routing
Positioned some of the components in the gas gauge circuit, androuted a few wires.
Started routing charging updated charging circuit
Routed some of charging circuit in updated Scoutfly. Modeled partposition after that on power test board. Moved diode and capacitor outof the way to get inductor closer to charging chip. This will make it...
Fixed angle errors in Scoutfly power update.
Scoutfly power update now passes DRC.
Moved power parts in Scoutfly layout
Moved parts for new Scoutfly power circuit from edge of layout to their(very) approximate final locations. Changed the battery and chargerconnectors from vertical to horizontal Molex connectors.
Added Scoutfly files with new power circuit
Switched Scoutfly from old power circuit to new power circuit from powertest board. Did this in a new file so that, if the power circuit turnsout to be a failure, other changes made contemporaneously to Scoutfly...
Added power board CAD files, deleted autoroute
Added files used for manufacture of power test board. Removed copy ofpower test board files used to run autorouter, as it will not be usefulnow that manually routed version has been manufactured.
Turned on "always vector font" in Eagle options
While editing power test board, turned on the "Always vector font" option in Eagle. Honestly, I might have done something else to thesilkscreen, but I can't remember what. I'm pretty sure I didn't messwith any of the actual components.
Fixed silkscreen ugliness in power board
Went through layout and changed ugly names and values to good ones.Moved text off of vias and pads and out from under things. Deletedgiant, useless USB port and ISP header labels. Added description, dateof design, and attribution in corner.
Adjusted position of VUSB decoupling cap
Increased widths of several high-current traces
Mostly GND around charging circuit and gas gauge
Decreased trace width between gas gauge resistors
Decreased width of trace between 49.9KOhm resistors in gas gauge voltagedivider to reduce noise.
Widened battery and charger traces
Widened to 20 mils some traces that come from the battery and chargerconnectors, because they carry higher currents.
Added ground poly under charger IC
Added polygon under LT3650 IC and updated it to new device from kwoolibrary. It now has effectively both a ground pad and a via. Slight areaof no contact right around via may be unavoidable.
