Rev200 MC interface connectors
- motor connectors HP-CON25 3MF
- SC/MC300 - Signal J8.3 (ANALOG_EXTPWR) is by default connected to 24v supply. Need to change jumpers for 5V supply. This is used to power the joint ankle sensor.
todo
assembly notes
- white LED has black text marking the index pin (die is faintly visible also)
- add note to assembly docs
- QY1 needs to be installed upside down and slightly rotated, as pins 2 and 3 need to be flipped
- add note to assembly docs
AKENCxx interface
- GND (blk) -> PENC1.7
- +V (red) -> PENC1.6
- NC
- NC
- AN0 (blk) -> PENC1.4
- DIG1 (grn) -> PENC1.5
PCBs
errors
- PIC32 FUP, and SWIFI outputs need their serial ports swapped
- PIC32 FUP needs PGC and PGD swapped
performance
- pic32 contains timing result for the firmware and various speeds.
notes
052710
- MC firmware : on bmech2, ricpf, trunk, MC; used vlist:ak_p32.vlist
status
- SN1 : use for dev;
ECO1
- rotate and reverse QY1
ECO2
- install jumper from C84 to PSW2.1 (brings Vsup to the SWIFI side connectors.)
ECO3
- install 20K between pins 8 and 9 of PKNE1
- install Schottky between CY1.1 (cathode) and QY1.2
- reduce RY1 to ~1k
