- phone w/DG re LTF results
- phone w/GG re LTF an robot results
- read patent proposal
fri jan 8
- 1 hr
- working with DG on LTF
sat jan 9
sun jan 10
- 2pm - 8:45p -30
- meet w/RC @CKF - discuss robot testing, holster, block diag, belt detector
- review SERDES
- discuss SERDES ideas w/MM - decide on FPGA w/1 TX, RX, CLK
- review of patent
- consider alternatives to connecting to SC/MC. Possibly HS USB?
mon jan11
- 4-9pm
- discuss robot arm control w/ZH and GG w/python
- discuss w/GG java UDP for plot_lifefix
- work w/DG on LTF. Run white noise tess, followed by a large series of sine sweeps.
tue jan 12
- 1.5 hrs - reading patent
- 3-8:30p
- sign patent papers
- review matlab UDP java tool
- wire up new LTF power supply.
- work with DG on LTF freq response, and biquad filter.
wed jan 13
- 1 hr
- investigate methods of multiplexing ISP for debug deep in the robot.
- 3 methods:
- develop our own programmer that MPLAB can use (or copy one)
- implment the ISP statemachine in the FPGA so it can determiante directionalty
- use an analog swtich to multiple the PGD signal - so we don't have to understand the protocol, use SER-DES for the remaining signals.
- 4pm-5:30p
- cut pcb pannel
- assemble eddy current sensor PCB and test.
- ???
- 6:15pm - 10:15pm
- work with DG on LTF.
- verify freq rsp of pole zeros with fvtool
- calculate new pole zeros
- test biquad on LTF
- start run_lifefix_v2, issues with KCA.
- work with DG on LTF.
thur jan 14

- bring up LTF, try to understand commutation problem
- LTF PID tuning
- LTF work loop studies.
fri jan 15
