Changed USB port drill holes back to spec
Looked at mini USB port with Dan. Observed that corner drill holes aresupposed to be multiple drills right next to eachother. Decided tochange holes back to specfied radius and ignore long hole for now.
Updated DS2786 footprint in kwoo library
Updated package footprint for DS2786 in kwoo.lbr based on recommendedland placement in datasheet for DFN10 package. DS2786's datasheet listsTDFN10 as its package type but doesn't give placement guidance or auseful package description. Unable to find a datasheet for TDFN10, but...
Increased mini-USB plug drill hole size
Imported MINI-USB- device from Hirose Connectors library into kwoolibrary. In UX60-MB-5S8 package, increased drill hole size on cornerpins from .8 mm to .9 mm. I did not drill out the original too-smallholes on Scoutfly, so I don't know whether this is sufficient or not....
Updated kwoo.lbr with previous kwoo changes
A few months ago, Kevin sent me a new version of kwoo.lbr. Updatedkwoo.lbr with these changes (using the Eagle update command). Also ranupdate in scoutfly.sch. This did not affect the results of erc or drcfor scoutfly.
Finished hooking up new gyroscope.
Connected pitch output of gyroscope to AVR and gave pitch an output LPF.Added optional HPFs to both pitch and yaw outputs. We can just leave thepads empty if we think they won't be useful.
To route the changes, had to squeeze some other stuff. Moved the AVR...
Swapped gyroscope part in schematic.
Replaced old gyroscope part with new one in schematic. Assuming thatpitch output or amplified outputs are undesired. Not using optionalhigh-pass filter on output. Have not yet routed connections to gyroscopeon board.
Began fixing bugs for Scoutfly fixup.
Made several of the changes listed on wiki page ScoutflyUpdate2011. Inparticular:Removed R4 and connected pin 4 on U$3 directly to VCC.Connected VREG_EN to VCC with 10 kOhm resistor (new R4).Changed value of R26 to 100 kOhms....
updated scoutfly and kwoo lbr with dual NPN
updated scoutfly with new jst parts
swapped jst-5 headers from right angle to vertical
changed accessory pin names and moved one to sonar.
added grounded srew holes to scoutfly. for review by kwoo.
changed the value on the accessory detect pin resistor divider to a standard value
added silk, fixed layout bugs
Layout completed. Need to fix silk
Finished layout for steppers and battery/charging contact support circuitry
Floorplan for the new stepper controller
Replaced stepper controller with one that will work for our voltages, fixes to the AVR on the clock and decoupling caps
AVR and BOM layout completed.
Gumstix layout mostly complete, AVR layout started. Some additional notes around the stepper driver on configuration, changes to the SPI header
Removed USB power since it would not work, simplified power area, reordered pins on the level shifters for easier layout.
Removed extraneous pullups from stepper controller
Fixed some pull up/down bugs
Started layout on scoutfly, updated schematic to use gumstix
Copied old atmel version of the scoutfly to the current version
Backed up the scoutfly atmel version in the repo
Fixed issues with non-standard resistor values
Fixed error in smybol for the Power OR controllers where the FET's drain only had 1 out of 6 connections. Finished redoing the floorplan on the Power OR section. Routing done for the top and bottom layers. Only need to do the power plane level now.
Added SPI lines to the wireless chip and the control lines. Replaced standoff terminals with the Sparkfun parts which have better keepouts for the screwheads.
Routed all signal wires out of the ARM. Still need to do final connections. Moved flash jumpers and debug port around to facilitate routing
Finished routing PSU, user buttons, fixed a bug in tolerances in the wireless chip.
Reorganized the I2C pins on the FFC. Routed I2C and the I2C levelshifter. Finished the PSU poly pours except for the VCC pour. The Motor current limiters are laid out except for the VCC connection. Hooked up the wireless chips except SPI. Added a mounting hole for the BOM board.
Some PSU routing, WL chip except external signals is done. Fixed resistor size (package) for the MAX745 battery charger
Routed AVR, motor drivers, JTAG, USB ports, debug UART and some of the decoupling caps across the board.
Initial commit of the unfinished scout board and the current scout library
