| 21:44 | Fix the Fundumoto class so it actually works check-in: 76b27716eb user: mwm tags: trunk | |
| 15:28 | Tweak comments & readme. check-in: 779249a2f4 user: mwm tags: trunk | |
| 15:17 | Rewrite the servo driver to use the new PMW µ-second pulse length/width code. Document it as such. Fix pulse_width function to use the pwm pulse_width, not the channel one. Fix min/max/centre to default to the appropriate percentages. Calculate angle from pulse widths, not stored. Add speed code. check-in: ef922f4041 user: mwm tags: trunk | |
| 12:47 | Add pulse width control. Pulse_width is measured in µ-seconds. We now calculate percentage from the timer values rather than saving it, as changing the pulse_width changes the duty cycle. Also change the "width" parameter to "length", as it's the length of the cycle, not just the on pulse, which is conventionally "width". check-in: d4c36aef38 user: mwm tags: trunk | |

| 10:49 | Refactor the hbridge drivers. fundumoto.Fundumoto class with motor(motor_name) method. Add drv8835.PololuShield with motor(motor_number) method. Fix hbridge to set speed to zero for coast/brake in RUN_* modes. check-in: 68761ff1ca user: mwm tags: trunk | |
| 09:21 | Tweak descriptions of motor driver layers. check-in: cf0bf9ffeb user: mwm tags: trunk | |
| 09:01 | Move pwm2.py to top level directory. check-in: 2c71522ffc user: mwm tags: trunk | |
| 09:01 | Rewrite the h-bridge description, add pwm. check-in: 835ec572d5 user: mwm tags: trunk | |

| 10:43 | Add the HCSR04 sonic rangefinder driver. check-in: 3e3c8ffbdb user: mwm tags: trunk | |
| 10:31 | Add the BSD license check-in: b19992fe4c user: mwm tags: trunk | |
| 09:57 | Add the package import point. check-in: 5a39d4d727 user: mwm tags: trunk | |
| 09:54 | Refactor into a package and logical modules. HalfBridge (renamed to HBridge) is in hbridge.py. Gang is in gang.py DRV8835 is in drv8835.py and uses HBridge. fundomoto just shows the NWO. Added hbridge.md as a text explanation of hbridge behavior. check-in: ff3b4aa227 user: mwm tags: trunk | |
| 09:53 | Add note about not working with 3.3volt logic, not tested check-in: 73590cb43a user: mwm tags: trunk | |
