ooh shiny pic - lamp controller

Here's an 8-channel lamp controller and lamp module. That's an ESP12e wifi/microcontroller module with an extra 8Kx8 serial eeprom, a PWM generator, e-fuse protected voltage main, two pushbuttons, and a Lesser Injection-Molded Polybutylene Guardian of Darkness. The lamp modules have 24 Cree 3500K 90...

Re: PCA9685 PWM Driver

I think there may be a bug in the servo.py file. In class init, setting period before calling _us2duty() (to set the min and max duty) seems like a good idea.

Re: RadioHead Packet Radio library?

It's all good... more code examples the better, and I'm very much asking for help with something which you're familiar. Anything that avoids having to read the data sheet and hook hardware up to a digital delay oscilloscope is worth a lot of coding time. I haven't looked at how much work it might be...

4DOF Hexabot controller

Here is the start of a 6-legged (4 joints each) small hexabot walker control board. It's currently a big pile of permaboard fritzed Adafruit modules (I soldered them all down just after this photo), but considering moving all of this onto a PCB with Eagle. This board will be bolted into the bottom o...

Re: RadioHead Packet Radio library?

Those answers are pretty much exactly what I needed. I know difficulties with C/C++ linkage, so as that hasn't happened with anything else yet, I know I don't quite have the skill to do that (without a lot of eye strain and aspirins). I hadn't seen the LoPy at all (hey, I also don't own a working te...

RadioHead Packet Radio library?

( http://www.airspayce.com/mikem/arduino/RadioHead/ ) As much as I like the idea of porting as much code into MicroPython as possible, I have need of the RadioHead C++ library. I've been reading the forums for a few days, but I can't seem to find any example of a C++ library being compiled into the ...
