tue jun 1

• 8am - 9am
  • continue debug of USE_AAS_SSI_MASTER_TIMER mode for AKENC
• 9:30 - 12:30 conference call
• 12:50 - 1pm HH

• 1pm - 6pm -30
  • continue debug of USE_AAS_SSI_MASTER_TIMER mode for AKENC
  • verify that cmd 123 0 will turn off switching of FETs
  • compare noise from ADCs with SSI
  • complete build 2691 - works with both ADC and SSI mode.
  • work w/GG re installation of firmware
• discussion w/RC re status

wed jun 2

• 20 mins - preventative repair of SWIFI

• 10am - 7:30pm -30 mins
  • kit and deliver components for AKENCxx; create DOCs
  • reinstall all PIC tools on PC.15
  • discuss AKENC3 status with GG and HH
  • work w/GG and H2, find MC firmware version is old.
  • investigate noise on sensor, caused by MC communications

thur jun 3

• several phone calls earlier in the day.
• 4:15pm - 11:15p (1 hr)

fri jun 4

• phone calls in the morning.
• 1pm-1:30p
• 3pm - 7pm
  • recode MC firmware for RMB20 + MILE
  • testing on H2
• 10:10pm - 11:20p
  • retesting MILE, RMB20 code. find there is a timing anomaly due to new compiler removing NOPs. Add optimization detection.

sat jun 5

• 8:50a - 3pm
  • discussion w/HH re status, BV
  • investigate MILE encoder - seems to be 10 bits only - output remains high after 10th rising edge. - expected 16 bits
  • [AMD256D01] 1.2uS min clock period, 0.6us min high,low, monoflop 16-22uS
  • discuss betaangle calculation with RC, ZH. my test code beta_test.m doesn't seem to give meaningfull results.
  • want to invert beta_angle calculation to go from AAS to motor rotations
  • specify calibration constants required, along with method to obtain them for calb fixture.
  • discuss calibration tables, EEPROM loging with GG.

sun jun 6

• 1 hr ; study the beta_calc problem with ZH

mon jun 7

• 50min - re-run beta test using theta0 = motorangle/210; email on same

tue jun 8

• 45 min re project status w/RC

wed jun 9

• 12:30 - 9:45pm -3 hrs
  • contacted L-tronics re status of hardware
  • experiment with SPI hardware for SSI slave
  • CA calls about wire
  • RC calls about imped offset
  • ED calls about operation of VLIST, general questions about dataport interface.
    • we need to rewrite class V2 packet to not read 512 bytes (hard to be real time!)
    • would like to write an data source aggrigator
  • receive AKENCxx PCAs; find that not all components in kit and BOM were populated; fixed AKENC3m
  • RC/CA calls about RMB20 resolution

thur jun 10

• 7:45a
  • testing SPI SSI slave.

sat jun 12

• 1 hr
• 1pm - 7:15pm
  • asssit with statemachine,
  • assist with benchtest motor testing
  • develop calibration program for hardstops and theta theta table.
