Marty's back from the future!

Hi! I'm finally making tests with my Wipy 1.0 (kickstarter) boards... My first project is to replace an Arduino I used to make a fancy Stargate clock, using RGB bus leds. The nice thing is I will be able to automatically sync with a ntp serveur to set the current date/time. I used a recipe for ntp, ...

Re: T6963C LCD Graphics Controller Chip

Yes, I know these projects; I'm working on the Arduino library, to clean it up. Then I will start to port it to micropython.

The idea is to dedicate a pyboard as a LCD interface, to build some sort of VT100 terminal.

Re: Servo resolution

Thanks for you answer! Good hobby servos have resolutions of 2-3µs, I guess. Even the chineese one I'm testing, which is pretty bad regarding resolution, takes avdantage of a 1µs resolution, over 10µs... It is really simple to change the timer5 init in micropython code, so the Servo class has 1µs re...

Re: Servo resolution

Yes, no problem for a fix pulse width, but what the Servo class does, and your examples don't, is managing the pulse width variation speed...

I vote for this solution ;)

Damien, could it be possible to:
- have 1µs resolution (timer5 config)
- add a 'time' parameter to the pulse_width() method, so it works like the angle() method, allowing precise control over position/speed

Thanks!

Re: Servo resolution

Is there a way to overwrite timer5 configuration when using the Servo class, so I can still use this class, but with 1µs resolution?

Re: Servo resolution

Thanks for your answer. I'll give a try to your code, to see if 1µs resolution improves the servo behaviour.
