Jove Yuan Laser programmer

  • Jove Yuan laser is not reliable (running master code to test optical program)

  • through the multiple lasers to program, the laser on the top works

  • Alex Moreno the alignment of the laser to the board is a problem?

  • a closure for SCuM could be an idea?

  • Kristofer PISTER we are trying to get rid of the hazard IR part.

  • Jove Yuan according to Brad’s thesis: if the pulse of the laser is shorten (through oscilloscope) then [not sure what’s this] length, the program should be fine.

  • Another thing, can’t rely on the SFD_OPTICAL_RAW_DATA interrupt correctly receive data to determine the board is functional.

  • Kristofer PISTER there are million of bits transfer which is hard to tell through oscilloscope.

  • Kristofer PISTER Jove Yuan should look at the digital output of the optical receiver (not just the RAW signals) and use a logic analyzer to see what the bit error rate is as a function of programming parameters: LED type, 4 pulse length settings, distance, etc.

  • Kristofer PISTER Jove Yuan should fill in the table with LED performance to include the actual measured drive current of the LED (which should be at or above the rated value on the datasheet) and the expected power density (mW/mm2) at 1cm distance.

  • Kristofer PISTER if we are trying to use an enclosure, why not using the 3 wire bus to program?

  • Tengfei Chang

    • update code organization next time
