mon jan11
- 4-9pm
- discuss robot arm control w/ZH and GG w/python
- discuss w/GG java UDP for plot_lifefix

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.
