Aim
- maintain frame,
- Avoid too many satellite PCB's,
- more powerfull 5V,
- fix PCB errors on version 2,
- new servo interface plug
Status and observations
REGBOT 36 LIV has new board (and new battery/charger mount (3D print)
- Line sensor low power pin (Teensy pin 25) now working. Pin 25 set to output in main.cpp (line 125), and pulsed in main.cpp (line 425 and 466). Line estimate seems OK (after calibration) - line sensor calibration missing in regbot.ini.
- Space for charger is too small - hits line sensor 6-pin plug on main-board and hits line sensor 90 deg 10-pin plug in other end. Should lower buttom plates by e.g. 4mm.
- Battery power (XT60) should have small plug on main PCB, so that XT60 plug can be fixed to battery/charger mount.
- IR sensor power control is OK. IR sensor calibration missing in regbot.ini.
- Power off by "halt" and by too low battery voltage is OK, back on by "power" button in both cases OK. Power off (by halt), no USB, then power on by power button is OK.
- wifi (on board part) is working (client is not) - tested with putty (not on SSID=device)
- Servo plog (teensy pin 25 (PWM) is also line sensor pin, teensy pin 5 (PWM) is also SPI interface, teensy pin A14 (analog out), teensy pin 18 (also linesensor power pin).
Teensy pin assingnment
- 0 serial RX (wifi)
- 1 serial TX (wifi)
- 2 motor left direction
- 3 motor left PWM
- 4 motor left enable
- 5 SPI CS og servo pin 3
- 6 Start button
- 7 motor slew ctrl
