Hm, I'm not able to reproduce the issue. I'm using a Saleae digital analyzer. Setting the frequency=50hz and dc=10% on hardware PWM channel 1: Similar results with PWM channel 0....
Huh, okay, so something is definetly up. My partner has a beefy scope, I'll get them to help repro this on our end.
Very useful, thanks @BasVDriel. Running `vcgencmd measure_clock pwm` on an Rpi 3 gives 100000000. So I think the difference is due to Pi 4s vs Pi 3s. I'll spend some...
Follow-up: working on this issue this week
Hm, so I had a moment to test with with an RPi4, and I'm still not able to fully reproduce it with either hardware pin. Some examples of what I'm...
See #10, specifically https://github.com/Pioreactor/rpi_hardware_pwm/issues/10#issuecomment-1998681462
Neat! Looks like a fun project!
An idea: is it possible that your `on_message` is freezing up / failing and blocking? How simple is the `on_message` callback?
A few others have noted this before, but thanks for bringing it up. I think this is a convergence issue -- the first model is naively trying to estimate N...
I'm glad you ran the mcmc with more samples, it's confirmed to me that something is amiss. I believe you are correct too... Let me get back to you on...
